The experiment will send particles called muons—heavier cousins of the electron—around a 50-foot-wide muon storage ring that was relocated from Brookhaven National Laboratory in New York state in 2013

Most powerful high-energy particle beam for a neutrino experiment ever generated.

The American Physical Society has recognized the U.S. Department of Energy’s Fermi National Accelerator Laboratory as a Historic Site for its nearly five decades of contributions to high-energy physics.

Two experiments at the Large Hadron Collider at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, have combined their results and observed a previously unseen subatomic process.

The Italian experiment – the world's largest of its type – will become an integral part of the future of neutrino research in the United States.

Earlier on April 5, the world’s most powerful particle accelerator began its second act. After two years of upgrades and repairs, proton beams once again circulated around the Large Hadron Collider, located at the CERN laboratory near Geneva, Switzerland.

The newest particle accelerators and those of the future will be built with superconducting radio-frequency (SRF) cavities, and institutions around the world are working hard to develop this technology. Fermilab's advanced superconducting test accelerator was built to take advantage of SRF technology accelerator research and development.

Top quarks are the heaviest and among the most puzzling elementary particles.
