Cosmic Muon Lifetime measurement - Kamiocan -
Muon lifetime.
In Cooperation with:
Principle The Muon is an elementary particle similar to the electron, with unitary negative electric charge and a spin of 1/2. Muons, electrons, and neutrinos are classified as a leptons. Most naturally occurring muons on earth are created by cosmic rays, which consist mostly of protons, arriving from space at very high energy. The measurement of muon properties such as its lifetime and studies of the electroweak interaction without radioative sources in a clear experimental setup is realized in cooperation with the University of Göttingen and Netzwerk Teilchenwelt. It is named "Kamiokanne" according to the Kamiokande experiment in Japan. Tasks 1. 2. 3. 4.
Calibration Muon rate determination Muon lifetime mesurement Coincidence, angular distribution
