In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together to solve the puzzle.
The CMS (Compact Muon Solenoid) detector at CERN, in Geneva, Switzerland, and the new CMS offices at Fermilab are separated only by the amount of time it takes light to travel between the two places.
In January 2000, Tom Jordan had just finished up a conference in San Diego, where he had presented one of the new cosmic ray detectors to QuarkNet teachers.
Because particle physicists cannot directly see the objects they study, they rely on deduction and decay products to detect nature's tiny, ephemeral particles.
Fermilab's new Girl Scout badge has troop #312 excited about "atoms and buffalo." Unlike a field trip where kids visit Fermilab to learn about physics in an "educational environment," the Girl Scouts' Fermilab outing lets kids come with their friends and a scout lead
Custom designed microchips have become essential in processing signals from modern physics experiments that generate lots of data. This chip, the QIE9, designed by Fermilab engineers, is just one example of the many Application Specific Integrated Circuits (ASICs) used in such experiments.
