Cosmic ray measurements by scintillators with metal resistor semiconductor avalanche photo diodes

Abstract

An educational set-up for cosmic ray physics experiments is described. The detector is based on scintillator tiles with a readout through metal resistor semiconductor (MRS) avalanche photo diode (APD) arrays. Typical measurements of the cosmic angular distribution at sea level and a study of the East–West asymmetry obtained by such a device are reported.
