Tevatron record

The Tevatron accelerator at Fermilab set a world record on Sunday afternoon, July 3, 1983, achieving a beam energy of 512 billion electronvolts (GeV). Accelerator operators had made the first-ever attempt at accelerating a beam in the Tevatron at 3:12 a.m. that day, reaching 250 GeV.

Hunting the origin of Alzheimer's

A surgeon and a scratch golfer most of his adult life, a US Army officer in World War II, the doctor gave up his medical practice in his 60s while exhibiting increasingly erratic behavior–such as meandering down to a favorite car dealer in his prosperous New Jersey town, and signing the pap

PEP-II interaction region

The Stanford Linear Accelerator pumps large amounts of energy into beams of electrons and positrons, sending them into the PEP-II storage ring where the particles can collide, revealing the secrets of fundamental particle processes.

Old giant hangs on

In biology, there is a loose rule of thumb that says the bigger an organism, the longer its life will be. If Fermilab's "Jolly Green Giant" is any indication, the rule may also apply to equipment in high-energy physics.
