Cosmic-Ray Detector

Description

An Anton 314 omnidirectional Geiger tube detector was used to measure the flux of energetic charged particles (protons E>30 MeV and electrons E>3 MeV). The detector was saturated much of the time. The experiment performed normally until March 16, 1958, at which time the batteries powering the Geiger tube circuits became exhausted. No usable data were received after that time.
