Solar Proton, Deuteron, Triton Solid-State Telescope

NSSDCA ID: 1972-076B-01

Mission Name: RADSAT
Principal Investigator:Mr. Ludwig Katz

Description

This experiment was specifically designed to measure protons from 5 to 70 MeV, deuterons from 3.1 to 30.6 MeV/nucleon, and tritons from 2.4 to 23.0 MeV/nucleon during solar events. The detector assembly consisted of four solid-state detectors with a plastic-scintillator anticoincidence shield. The two frontmost detectors were 101 and 109 microns thick; they were oriented perpendicular to the spacecraft spin axis and they provided a field of view of 6 deg half-angle for the telescope. The remaining sensors, which acted as one, were 5-mm-thick lithium-drifted silicon detectors. The detector outputs were electronically combined to form a total-energy signal and a particle-identification signal, the latter being almost energy-independent for a given isotope. The detector functioned well for its first year of life, then less well for the next 6 months. The experiment was turned off April 2, 1974. Further details are found in P.L. Rothwell et al., "Upper limits to flare-produced deuterium and tritium," Phys. Rev. Lett., v. 31, n. 6, pp. 407-410, August 1973.
