Community-based Investigation of Cosmic Radiation

Cosmic radiation are high-energy particle rays produced in outer space which constantly impinge on the Earth's atmosphere. These particles can produce particle showers when they interact with atoms in the upper atmosphere.

The MuonPi Project aims at investigating these cosmic showers by establishing a network of low-cost RaspberryPi-based particle detectors.

Join the Endeavor

While a single MuonPi detector already allows the investigation of cosmic ray muons, a wide-spanned network of the detector units can resolve the entire particle shower geometry and unveil the physics of cosmic radiation.

New live map of coincidences

05 January 2021

The new live map shows all 'L1' coincidences between (two or more) active detector stations. The events are mostly random coincidents but could also come from a single cosmic showers. The more detectors in one event the more likely it is that it is a cosmic shower that was just detected.
