Solar Gamma-Rays in the 50- to 500-MeV Energy Range

NSSDCA ID: 1972-014A-05

Mission Name: TD 1A
Principal Investigator:Prof. Giuseppe Occhialini


A combination of scintillators and photomultipliers were used to detect solar gamma rays (photon energy < 50 and > 500 MeV) while discriminating against charged particles. A directional accuracy of a few deg was achieved. The effective area of 100 sq cm allowed a background of 1.E-5 photons/sq cm-sec to be obtained while the dynamic range allowed fluxes up to 1.E-2 to be measured during solar flares.
