Fermilab takes stage in The Da Vinci Code-like physics thriller

June 12, 2008 | 6:30 am

Albert Einstein agonized that his special theory of relativity enabled the creation of the atomic bomb. He would not have wanted to hand another theory with military applications to a still violent world, particularly if that theory leads to production of a weapon more powerful than the A-bomb.

Yet, the love of knowledge likely would prevent Einstein from destroying such a successful theory.

So what would Einstein do?

Mark Alpert has an enticing theory of his own that Einstein did succeed in his two-decade quest to prove the Theory of Everything before his death in 1955. That theory, often termed the “Holy Grail” of physics, would remove the uncertainty in the universe, making it predictable. If Einstein succeeded, Alpert theorized, Einstein would tell his students to keep the theory secret until mankind could keep from blowing itself up.

“I can imagine a scenario where he would tell his assistants to just wait until there is a world government,” Alpert said. “These men would wait their entire lives. That is the sad part. You could argue that the world is worse off now.”

In Alpert’s book Final Theory released June 3, he mixes abbreviated particle physics lessons, with action-packed shoot outs and car chases as he explains a the attempt by a history of science professor to piece together the theory. Evil-doers race the professor to find the former students and mathematical equations of the theory to use it to build the most powerful weapon the world has ever seen. The two quests collide at the United States’ premier high-energy physics laboratory, Fermilab.

Why high-energy particle physics?

HEP provides an atypical setting for a fiction thriller, but Alpert views it as the perfect vehicle to introduce people to some of the real-life science theories and technological advances that he reports on as an editor of Scientific American. Many of the science fiction attractions of the past have become the doable science of the present.

“I think there is a huge increase in interest in [high-energy physics],” Alpert said. “Look at all the people who are interested in the LHC. I recently was at the World Science Festival. It was packed. And most of these people were not scientists. They don’t understand the math. I don’t understand the math. When I edit articles for Scientific American, I don’t put the math in, but people like the excitement of science. I think people key in on that.”

Unfortunately, a small segment of those people–especially mainstream media—key in on the excitement of far-fetched hypothesis of physics-powered catastrophes such as the lawsuit alleging the LHC startup will create a black hole that will swallow the Earth, he added.

Alpert scoffs at the idea. His book aims to promote science not mislead people into believing experiments, rather than their applications, are dangerous.

“In my book, the theory is dangerous. It is not the experiment itself that is dangerous. It is the military application of the theory that is dangerous.

“I don’t want to ever tell anyone we should not do research.” Alpert said.

“The message is: Let’s work on our humanity before the technology advances. The sad part is people can use research for military purposes. We should grow up as a species.”

Alpert, who received a bachelor’s degree in astrophysics from Princeton University, uses the scientific inquiries of his main character, a “lapsed physicist”, to impart lessons about the universe, science and the drought of US funding for scientific programs, particularly at Fermilab.

Readers should not get intimidated. The science comes in easily digestible bites mixed in with international espionage, strip clubs, and skin heads.

“It is mostly a thriller. A lot of car chases. I gave it to a 14-year-old son of a friend of mine to read, and he loved it,” Alpert said. You don’t even need a high school degree to read it.”

Why write about Fermilab?

The idea for the novel sprang out of research Alpert was doing on Einstein for Scientific American, as well as a trip to Fermilab to research a story on the shift to neutrino research.

In his first trip to the Batavia, Illinois, laboratory in 2006, Alpert was wowed by different approaches of how to find physics beyond the Standard Model, the current recipe for matter and the forces of nature.

At the energy frontier, the Tevatron, the world’s highest-energy particle accelerator, and its two four-story detectors, CDF and DZero, produce and analyze sprays of millions of particles each second from collisions at nearly the speed of light. The particles could hold the key to extra dimensions and new never-before-seen constituents of matter. Those particles are the same that existed a fraction of a second after the big bang and eventually combined to form the world we see.

At the intensity frontier, Alpert toured the BooNE/MiniBooNE experiment, which studies antineutrino events, where the world’s least understood fundamental particle morphs into its own antiparticle. That could produce a possible key to how  antimatter switched to matter 14 billion years ago, creating the universe filled with planets.

“In the back of my mind, I was thinking this is great thriller material. It is very James Bond. There is so much going on here,” Alpert said.

The Tevatron control room, CDF collision hall, accelerator tunnels, Wilson hall, and MiniBooNE’s 40-foot-in-diameter detector filled with mineral oil–a flammable, dense material –create high-tech, unique settings for the book’s climax.

Alpert incorporated as many experiment specifics as possible into the novel to avoid the criticism of taking too much literary leeway, such as received by the book Angels and Demons set at the European high-energy physics laboratory CERN.

“I tried really hard to make it accurate, but for narrative reasons I changed little stuff,” he said. To help the villains, a supply closet materializes near the CDF collision hall and the MiniBooNE detector opens easier than usual.

CERN, which will have a beam seven times the power of the Tevatron, has captured the imagination of the world and could have provided Alpert’s setting. But he wasn’t seduced by the new experiment on the block.

“I was just so impressed with the Tevatron,” he said. The accelerator performs at near perfection; 300 times better than expected in the original design. “Until the LHC comes on, this is the most powerful (accelerator) in the world, and there may still be some amazing physics to come out of here in the next few years.”

MiniBooNE, an example of neutrino research, not done at CERN’s LHC, also provides another portal to physics that could change forever the way we understand our world.

“I really had so much fun on the tour and the excitement that is going on there,” he added. “I tried to inject that into the book.”

GLAST launch successful

June 11, 2008 | 12:55 pm

Here is the text of the news release NASA issued about the launch of the joint Department of Energy/NASA mission:

CAPE CANAVERAL AIR FORCE STATION, Fla. — NASA’s Gamma-ray Large Area Space Telescope, or GLAST, successfully launched aboard a Delta II rocket from Cape Canaveral Air Force Station in Florida at 12:05 p.m. EDT today.

The GLAST observatory separated from the second stage of the Delta II at 1:20 p.m. and the flight computer immediately began powering up the components necessary to control the satellite. Twelve minutes after separating from the launch vehicle, both GLAST solar arrays were deployed. The arrays immediately began producing the power necessary to maintain the satellite and instruments. The operations team continues to check out the spacecraft subsystems.

“The entire GLAST Team is elated the observatory is now on-orbit and all systems continue to operate as planned,” said GLAST program manager Kevin Grady of NASA’s Goddard Space Flight Center in Greenbelt, Md.

After a 75-minute flight, the GLAST spacecraft was deployed into low Earth orbit. It will begin to transmit initial instrument data after about three weeks. The telescope will explore the most extreme environments in the universe, searching for signs of new laws of physics and investigating what composes mysterious dark matter. It will seek explanations for how black holes accelerate immense jets of material to nearly light speed, and look for clues to crack the mysteries behind powerful explosions known as gamma-ray bursts.

“After a 60-day checkout and initial calibration period, we’ll begin science operations,” said Steve Ritz, GLAST project scientist at Goddard. “GLAST soon will be telling scientists about many new objects to study, and this information will be available on the internet for the world to see.”

NASA’s GLAST mission is an astrophysics and particle physics partnership, developed in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden, and the U.S.

GLAST launch: live blogging

June 11, 2008 | 10:00 am

Live blogging the GLAST launch (due from 11:45 a.m. EDT)

Photo of GLAST launch (right) courtesy of NASA TV.

There isn’t a lot more for us to talk about right now so we’ll leave you to explore GLAST science more. Here is a starting point.

1:40 p.m. Steve Ritz is talking on NASA TV now. Both solar arrays are out and operational. Now there will be two weeks of checking out the spacecraft, then the instruments turn on and get checked out and calibrated. Preliminary observations take place and then about 60 days from now, the first science observations begin.

GLAST is safely in orbit and the scientists’ main work begins! We’ll keep you updated in symmetry about what is happening throughout this process and let you know as soon as we can about science results and observations.

1:30 p.m. The first solar array has deployed and is receiving electrical current. Great news! The second array is deploying now.

1:28 p.m George Diller is commenting that the launch happened only just before weather conditions prevented the launch. The NASA commentators are now talking about the next NASA mission but those of us interested in GLAST just want to know what is going on with the solar panels!

1:23 p.m. In the NASA launch control room, people are looking a lot more relaxed, mingling and talking. Solar array deployment will start in a few minutes time to provide power for GLAST. At this point, the GLAST scientists are watching anxiously because getting the satellite up into orbit is just the first challenge!

1:22 p.m. The spacecraft is pulling away from the second stage.

1:20 p.m. NASA announces the separation indicator has come on. The deployment sequence continues.

1:20 p.m. The separation nuts are released and separation imminent.

1:15 p.m. Burn is successfully complete. In the wonderfully understated jargon, the burn was “nominal.” Now the deploy sequence is the next major event in five minutes.

1:14 p.m. Ignition of second stage burn. A little over a one minute burn. Everything is going smoothly.

1:10 p.m. We are ten minutes away from spacecraft separation. There will be a two minute burn to get into the orbit prior to separation. After the burn, there will be a five minute coast period before GLAST separates from the Delta II rocket.

12:45 p.m. We’ll take a break from live blogging for a few minutes as we wait for the next stage–the shift of GLAST from its parking orbit to its operation orbit and then deployment.

12:32 p.m. KIPAC people brought in a few bottles of soft drink for a toast (no alcohol allowed on site) and Jonathan Dorfan toasted the LAT team, mentioning Eliott Bloom in particular who was one of the people responsible for initiating GLAST about 16 years ago. (It’s also Eliott’s birthday today so this seems a great birthday present for him!)

12:20 p.m.  With the NASA broadcast over, people are getting up to leave.  SLAC Director Persis Drell, who has been sitting in the front row, stands up and says, “Before everyone disperses, I just want to congratulate the GLAST team. This is a tremendous achievement. The instrument is on its way into orbit, there are 10 years of science ahead of us–great job!” Persis has a special interest in this launch; not only is this one of the lab’s major initiatives, but before she became director she had hoped to participate in the science.

She talked about GLAST in a recent interview with symmetry. You can see the article here and a transcript of the interview here.

You  know, my greatest frustration with this job I have is that GLAST is going to launch soon, and there’s a big piece of me invested in that instrument, and I’m not going to get to have fun with the first data. And whereas I’m not ever going to be a world-class gamma-ray astrophysicist – I wouldn’t even dream of doing that – I also know that when you put up a detector that’s orders of magnitude better than anybody has ever put up before, even the novice can have fun….. I have been assured that on a dark night we will be able to see GLAST with the naked eye.  That’s a milestone for me, to see GLAST in the night sky.

12:17 p.m. In response to a question from former SLAC director Jonathan Dorfan, Rob Cameron says the Large Area Telescope won’t be turned on until 13 days into the mission, but we will be able to monitor the instrument’s temperature via telemetry.  In the next couple of hours, after the last stage of the rocket burns, the spacecraft has to deploy its solar panels; for now it’s running on batteries that only have enough charge for a few hours. We should be getting status updates on the overall health and safety of GLAST in two or three hours, he says.

12:15 p.m.  We’re not the only ones blogging the launch; NASA has its own blog here.

12:12 p.m.  The rocket is burning its second stage now and has accelerated to 14272 mph.   We now have a video feed from collaborators at UC Santa Cruz.

12:09 p.m.  Three minutes into the flight, velocity 9874 mph, and the rocket has disappeared from sight.  “Everything holding rock-solid,” the controller says.

12:05 p.m.   Liftoff!  Hearty applause and cheers,  then silence.   The solid fuel ignites;  “Nice!” someone says.

12:04 p.m. Absolute silence here.

12:02 p.m.   The hold has ended and we’re back on track.  T- two minutes 30 seconds.

12:00 p.m. Someone reports that there has been a red alarm — something to do with momentarily exceeding tank pressure — the resolution plan is to monitor the line pressure.  the tank pressure alarm has been disabled, there is small probability that we could …..   at this point the narration goes dead!  Nervous laughter all around.

11:55 a.m. Kyle Watters, one of Roger Romani’s grad students, who is sitting behind me,  fills me in on the live feeds we’re seeing from various collaborators around the world.  The darkened SLAC auditorium is in the upper left corner;  top middle is from Pisa; bottom middle is from Paris; top right is Silvia Raino from INFN-BARI in Italy; bottom right is Tomi Ylinen in Stockholm.

11:54 a.m. We’ve just been told the launch is rescheduled for 12:05 p.m.  The acceptable weather window for launch is expected to end in about 15 minutes, so things are tight.

11:47 a.m.  The tracking station is back up!

11:46 a.m.  We just learned the reason for the extension:  The downrange tracking station at Antigua Island is down, and  at this time they don’t know when it will be back online.

11:41 a.m.   The hold has been extended.  We’re waiting to find out the reason.  This is not at all unusual for a NASA launch.

11:39 a.m.  We’re looking at the control room where the button will be pushed — only in this case it’s a mouse click — to launch the Delta II.  There is about a minute remaining in this hold.

11:32 a.m.  Glennda Chui here, filling in for David.  The countdown is on hold at T-4 minutes; this is built into the launch sequence so controllers can run through their final checks.  Until now it was hard to hear the NASA chatter over the excited buzz from the darkened auditorium, which is nearly full now.  But now, so close, there is a sudden hush.   People are talking quietly and some are watching the preparations not only on the big screen but on their laptops.

11:05 a.m.: Launch control have announce T-30 minutes and everything is looking fine to proceed.

10:58 a.m.: The GLAST launch is due in about 45 minutes from now and many of the Stanford Linear Accelerator Center scientists are gathering in the Kavli auditorium to watch the live broadcast of the launch from NASA. SLAC is responsible for the primary instrument on GLAST, the Large Area Telescope, or LAT. We’ll be updating you with events from the SLAC site throughout the launch process.

Even though there are only about 25 people arrived in this room so far, there is a very festive happy atmosphere. It is obvious that most of these people have been anticipating the launch for a long time.

NASA is showing a mix of live footage and recorded video of preparatory events through the night including the rollback of the tower at 3:00 a.m.

GLASTcasts: Whet your appetite for tomorrow's launch

June 10, 2008 | 12:49 pm

After several delays, it looks like the Gamma-ray Large Area Space Telescope will finally launch tomorrow morning between 8:45 and 10:45 a.m. PDT. You can watch the launch on NASA TV via streaming video; pre-launch coverage starts at 6:45 a.m. It’s a time of elation and high anxiety for hundreds of people who have worked on the spacecraft, which will explore the last remaining gap in the spectrum of light reaching us from space–the highest-energy rays created by the most violent processes we know about, from supermassive black holes to pulsars.

The mission is a joint project of NASA and the Department of Energy, and Stanford Linear Accelerator Center, a DOE lab operated by Stanford University, was in charge of developing its main instrument, the Large Area Telescope. Housed in a cube 1.8 meters on a side–the combined width of 15 CD cases–it’s essentially a particle detector whose 880,000 silicon strips lie in wait to capture high-energy gamma rays. Laboratories around the world crafted parts of the telescope and shipped them for assembly at SLAC, which will also process the data from the telescope.

For a taste of what the mission has in store and the excitement surrounding the launch, check out these brief videos–GLASTcasts, NASA calls them. SLAC has more info here, and NASA’s site is here.

Physicists in Congress

June 10, 2008 | 11:44 am

Today’s New York Times has an interesting profile of the three physicists in the US Congress. Cornelia Dean interviewed Vern Ehlers, Rush Holt, and Bill Foster as a group about the role of scientists in Congress. The physicists presented a very clear unified message about their role, including some valuable opinions about what is important and what isn’t for a physicist-congressperson.

Here is one point that has been made plenty of times but seems to need repeating:

For example, Mr. Ehlers said, it is irksome to encounter people who ignore the scientific consensus that human activity contributes to global warming yet count on science to produce new sources of energy magically. “They sort of reject our reasoning,” he said. “But they will come back and say, ‘Science will find a way.’ “

Another important point, which I think is often lost in debates about what is appropriate science education, came out:

What is needed is not more advanced degrees, the physicists said (they all have Ph.D.’s), but a capacity to take the long view, what Mr. Ehlers called the scientists’ ability to see from the pre-Cambrian era to the space age.

I’d be interested in reading your responses to what the physicists had to say.

Iran pursues the sciences

June 9, 2008 | 8:05 am

Friday’s Washington Post had an interesting story about Iran’s push to become a leader in the sciences.  It highlights a visit to Sharif University of Technology in Tehran by Nobel laureate Burt Richter of Stanford Linear Accelerator Center:

“Mr. Richter is an example for us,” explained Ismael Hosseini, a 23-year-old electrical engineering student who had managed to get a seat near the stage. “But soon I will be able to listen to an Iranian scientist who has received a Nobel Prize for his or her work,” he said. “We are all studying and researching hard to receive this honor.”

Iran’s determination to develop what it says is a nuclear energy program is part of a broader effort to promote technological self-sufficiency and to see Iran recognized as one of the world’s most advanced nations. The country’s leaders, who three decades ago wrested the government away from a ruler they saw as overly dependent on the West, invest heavily in scientific and industrial achievement, but critics say government backing is sometimes erratic, leaving Iran’s technological promise unfulfilled.

A few days ago we wrote about one of the products of the country’s push for scientific excellence, theoretical physicist Yasaman Farzan, who was recently awarded one of the first Young Scientist Prizes from the the International Union of Pure and Applied Physics.

Particle physics creates the right path to frontiers

June 6, 2008 | 7:13 am

The final day of the Fermilab Users’ Meeting set a course to discovery with an eye to the energy, intensity, and cosmic frontiers of particle physics at Fermilab.

But the course presents budget and outreach hurdles.

“It is very important not to be discouraged by the past,” said Joseph Dehmer, director of the division of physics of National Science Foundation. “I think we’ll have good coming years. The opportunity for discovery is greater than it has ever been at any time in history.”

Hundreds of users attended talks about Tevatron advances and analysis, proposed neutrino experiments, the US participation in CMS at the LHC, dark energy and dark matter searches, and research on a high-intensity proton beam.

US Congressman Bill Foster, a 22-year-veteran of Fermilab, urged users to attend the third Workshop on Physics to plan experiments that would meet short-and mid-term research goals.

“Don’t be afraid to try something new,” he said.

A culture that supports only short-term projects has hurt particle physics, Foster said, but the recent Senate approval of a supplemental funding bill and public interest in keeping the country competitive offer hope.

“Across the political spectrum there is recognition of the need for basic research,” he added. “The problem is keeping the politicians focused.”

Washington policy makers repeatedly stressed that particle physicists must make the case for the benefits of particle physics to the nation’s health, security, and economic well being.

“Advances in technology are not steady, but when it happens, it can change civilization,” Dehmer said. “Particle physicists are the most fearlessly creative group of people I know. They push the frontiers of technology and social organization.”

Fermilab hears views from Washington, DC

June 5, 2008 | 7:06 pm

The particle physics community is moving in the right direction to keep the field vital, but needs to increase the momentum amidst difficult budget times.

A series of talks Wednesday by Washington policy makers at the annual Users’ Meeting focused on how Congress and funding agencies view particle physics and what those groups want to hear from the field in the future.

Michael Holland, examiner for the Office of Science projects for the Office of Management and Budget.

The particle physics community has made great strides in presenting scientific opportunities on the energy, intensity, and cosmic frontiers and focusing on the excitement of discoveries on the horizon, said Michael Holland, examiner for the Office of Science projects for the Office of Management and Budget.

He called for the community to continue to engage further the public imagination in its research projects while also producing statistics for policy makers that show the broader benefits to the nation. Holland asked for more data on particle physics as a net exporter of talent and a pathway to national innovation.

The High Energy Physics Advisory Panel has undertaken a study of how many of those receiving degrees in particle physics go on to work in government and private industry, including the fields of computing, medicine, and finance.

“That will be essential for keeping you in the game,” Holland said. “People may be your most important product.”

Dr. Dennis Kovar, acting associate director for High Energy Physics at DOE’s Office of Science.

The work of the particle physics community to develop a “realistic, robust” P5 roadmap recently approved by HEPAP also strengthens the case for particle physics funding, said Dr. Dennis Kovar, acting associate director for High Energy Physics at DOE’s Office of Science.

The report sets the stage for the United States to become a world leader at the intensity frontier, building on Fermilab infrastructure, and to make exciting discoveries at the energy and cosmic frontiers, “There really is an exciting future,” he added. “The question is how do you get from here to there in terms of resources and making a case.”

The large number of particle physics connections with universities in dozens of states creates a great political asset for the field, said Adam Rosenberg, a Congressional staffer for the House Committee on Science and Technology. He stressed strengthening ties with other scientific fields as well.

The FY2009 budget scenario will require combined efforts because it is shaping up to be “eerily similar” to the FY2008 budget and could lead to a holding pattern in funding until the arrival of a new administration.

A continuing resolution likely would prolong the severe budget challenges for particle physics, Kovar said.

“We will do our best to ensure a world-class, strong program with the resources available,” he added.

CMS physicists prepare for LHC dress rehearsal

June 5, 2008 | 12:45 pm

Scientists across the world are eagerly awaiting the startup of the Large Hadron Collider, under construction in Switzerland. This also is the case at Fermi National Accelerator Laboratory in Batavia, Illinois, where scientists gathered today for the second day of their annual Users’ meeting. The day started out with presentations on the status of the LHC and the CMS experiment, one of the two general collider detectors that are being built along the 27-km ring of what will be the world’s most powerful proton smasher.

Jos Engelen, chief scientific officer at CERN, provided an update on the LHC schedule. The cooldown of the last LHC sector of superconducting magnets started at the end of May and the entire machine should be at its operating temperature of 1.9 K in July. This temperature is necessary for the magnets to become superconducting and to achieve strong magnetic fields. The magnets steer beams of proton around the LHC ring and make them collide at the centers of large particle detectors such as CMS. Four of the eight sectors have already been cooled to 1.9 K. Here is a chart of the current temperatures of all LHC sectors.

The CMS collaboration plans to carry out its final test of its detector at the end of July using cosmic rays, showers of particles that rain on Earth. Even 100 meters underground, the CMS detector will see a decent rate of muons creating signals in various detector subcomponents.

“This will be a full dress rehearsal,” said Joel Butler, US CMS project manager.

Scientists from US institutions represent about a third of the 2848 scientists of the CMS collaboration. “There are currently 203 graduate students in US CMS, and the number is growing,” said Butler.

The LHC experiments will shed light on how elementary particles obtain mass, look for dark matter particles, and search for extra dimensions, just some of the many research goals for its experiments. And, of course, scientists hope for the unexpected.

“The LHC is a discovery machine. There could be something new and exciting that shows up early,” said Butler. “We believe we are ready for the event samples that we will get.”

Here is Butler’s talk (PDF).
