||Cosmic-ray protons impinging on the upper atmosphere create showers of secondary particles, and the (relatively) long-lived muons resulting from pion decay reach the earth's surface to offer a free and reliable steady flux of fundamental particles for study. TeachSpin's 'Muon Physics' apparatus uses a single large scintillator, a photo-multiplier tube, and its associated electronics to make possible the study of muons' arrival. Happily, some muons come to rest in the scintillator, and decay within microseconds to produce a second detectable event.
Participants will see:
- how the configured apparatus produces a series of 'muon arrival events'
- what a 'Poisson process' looks like, and what can be inferred from it
- what a 'muon arrival followed by decay' event looks like, and how to measure muon survival time
- how to histogram the measured muon survival times, and how to interpret this histogram
- understanding mean life and half-life, and the lifetime for muons in matter
