Description
Relativistic dynamics experiment equipment.
This experiment is a study of the relations between energy, momentum and velocity of relativistic electrons. Energetic electrons from the beta decay of 90Sr and its decay product 90Y are sorted according to momentum by a 180 degree magnetic spectrograph, passed through a velocity selector, and detected by a PIN diode detector.
Plots of momentum and energy vs. velocity are compared with the theoretical relations of classical and relativistic dynamics, and the value of the ratio e/m is derived from the data.
