Physicists from MIT’s Laboratory for Nuclear Science have designed a pocket-sized cosmic ray muon detector using SensL SiPM sensors. The detector can be made entirely with common electrical parts, and when turned on, it lights up and counts each time a muon passes through. The relatively simple device costs just $100 to build, making it the most affordable muon detector available today.
The researchers, led by Spencer Axani, a graduate student in MIT’s Department of Physics, have designed the detector with students in mind. They have started an outreach program called CosmicWatch, with a website that lists parts to purchase and detailed instructions on how to assemble, calibrate, and run the detector.
