As seen above, the Cherenkov detector records the passage of cosmic muons through the water detector. The muon is an unstable particle which naturally decays into an electron and a pair of neutrino, with an average life of about 2,2μs. The decay of the muon is an event that can be recorded in our DIY Cherenkov detector.

Using the Bat Detector. Once the detector has been tested as far as it can be on the workbench and the dial has been calibrated, it's time to venture out at dusk. Hearing your first bat is a very satisfying experience. Start by setting the frequency to about 30 kHz. You should hear a uniform hiss in the background.
