Touching Invisible Cosmic Rays
Exhibitor: 加速キッチン / Accel Kitchen
Can you really touch an invisible cosmic ray? Take apart and rebuild detectors that let you feel cosmic rays through light, sound and vibration, side by side with junior- and senior-high-school students who observe from home. It's an interactive booth where, together with visitors, we think about how to share science you cannot see.
Free Admission No Registration
When a cosmic ray passes through, the detector glows, beeps and shakes. Including an enhanced version of the audio detector originally developed for people with visual impairments, these are inclusive detectors that let anyone catch cosmic rays with their own senses.
Bring a rock such as granite close to the detector, and the count climbs in real time.
Junior- and senior-high-school students who keep observing cosmic rays at home join as presenters. Take a detector apart and put it back together side by side, and talk together about how it works and what makes observing so much fun.
Accel Kitchen distributes and lends cosmic-ray detector assembly kits to junior- and senior-high-school students, supporting their cosmic-ray observation and research at home. To date we have supported more than 300 student observers. At last year's Science Agora 2025 we exhibited jointly with the High Energy Accelerator Research Organization (KEK).
