Proton-Electron Detector

NSSDCA ID: 1969-097A-04

Mission Name: Azur
Principal Investigator:Dr. Dieter K. Hovestadt

Description

This experiment consisted of two omnidirectional proton/electron detectors composed of cubical lithium-drifted silicon elements, heavily shielded on one side and covered by a hemispherical shield over a 2-pi sr solid angle on the other side. The detectors were used to measure trapped and solar protons and electrons, and the experiment was also used in conjunction with experiment 69-097A-02 (proton/alpha particle telescopes) to provide pitch angle distributions for protons above 20 MeV. One of the detectors was sensitive to electrons with E>1.5 MeV and protons with E>20 MeV in one electrical threshold mode and sensitive only to protons from 20 to 45 MeV in the other mode. Similarly, the other detector was sensitive to electrons with E>4 MeV and protons with E>40 MeV in one electrical threshold mode and sensitive only to protons from 40 to 72 MeV in the other mode. The experiment performed normally throughout the mission.
