Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do about an 800-ton magnet originally used to discover new particles? Send it off on a months-long journey via truck, train and ship halfway across the world to detect oscillating particles called neutrinos, of course. It’s all part of the vast recycling network of the physics community.
A video from SLAC National Accelerator Laboratory explains how the upcoming LZ experiment will search for the missing 85 percent of the matter in the universe.
At a recent workshop on blind analysis, researchers discussed how to keep their expectations out of their results.
From SLAC, June 1, 2016: Fermilab is one of the collaborating groups preparing to build an ultrasensitive ‘eye’ for an elusive form of matter.
