Solar Particle Telescopes

NSSDCA ID: 1969-046D-03

Mission Name: Vela 5A
Principal Investigator:Dr. Sidney Singer

Description

The solar telescope experiment was designed to measure the energy spectrum and angular distribution of solar protons between 0.3 and 50 MeV, and of solar alpha particles between 2 and 100 MeV. In addition, the experiment was designed to identify and monitor the flux of deuterium, tritium, and helium-3 nuclei which may be emitted during a solar particle flare and to monitor the intensity of more heavily ionized particles. There were three telescopes in a single plane oriented at angles of 45 deg, 90 deg, and 135 deg relative to the spacecraft spin axis. Each instrument consisted of a collimating tube (providing an angular view of 30 deg) in front of a solid-state dE/dx vs E particle detector. The telescope data system failed on May 29, 1969.
