CERN reveals plans for new experiment
Officials at CERN have approved a new experiment designed to identify light and feebly interacting particles. The Forward Search Experiment, FRASER, will compliment CERN’s ongoing search for dark matter, and will record their first data when the LHC starts up again in 2021.
For the experiment, scientists will assemble and install a new instrument inside the Large Hadron Collider at CERN, the European Council for Nuclear Research. It is the largest and most powerful particle collider in the world. The project was initiated by a team of physicists at the University of California, Irvine.
“Seven years ago, scientists discovered the Higgs boson at the Large Hadron Collider, completing one chapter in our search for the fundamental building blocks of the universe, but now we are looking for new particles,” Jonathan Feng, UCI professor of physics and astronomy, said in a news release. “The dark matter problem shows that we don’t know what most of the universe is made of, so we’re sure new particles are out there/5
Feng and his colleagues at UCI will collaborate with scientists from Europe, China and Japan, as well with physicists from other universities in the United States. In total, the new dark matter experiment will involve the efforts of 30 to 40 researchers.
The FASER instrument is a small device that will be placed near the collider’s massive underground tunnel, a 16-mile loop. The device will be positioned near the ATLAS instrument, which produces subatomic particles as protons pass through.
