CosmicWatch detector makes invisible cosmic particles visible
Spencer Axani, a physics professor at the University of Delaware, invented a particle detector called CosmicWatch. About the size of a box of animal crackers, it is built from roughly $100 in electronic parts. It lights up and counts muons, particles created when cosmic rays strike Earth's atmosphere. Students use it too. "CosmicWatch detectors allow us to do far more physics at a dramatically lower cost, in a compact and portable form, opening the door to many new kinds of experiments and outreach opportunities," Axani told UDaily on January 7.
High school students and physicists worldwide gain an affordable way to study particle physics, without expensive lab equipment.
