Proton Telescope

NSSDCA ID: 1969-097A-03

Mission Name: Azur
Principal Investigator:Dr. Juergen Moritz


Two solid-state devices were used in conjunction with four pulse-height discriminators to detect trapped and solar protons using coincidence techniques. The detector had six energy channels: protons from 0.25 to 1.65, 0.25 to 12.5, 0.5 to 1.65, 1.0 to 1.65, and 1.65 to 13.5 MeV, and alpha particles from 2.0 to 6.4 MeV. Electrons were eliminated from the incident beam by using a broom magnet. The acceptance cone was 20.4 deg full angle. The experiment worked normally until the spacecraft telemetry system malfunctioned in early July 1970.
