NSSDCA ID: 1963-013A-01
Mission Name: Telstar 2Three p-n junction, solid-state diodes separately measured protons (1) directionally in nine ranges from 2 to 30 MeV with an aperture of 25-deg half-angle, (2) omnidirectionally from 18 to 28 MeV, and (3) omnidirectionally greater than 50 MeV. A fourth p-n junction diode measured electrons with four threshold ranges (greater than 750, 900, 1200, and 1400 keV) with an aperture of 20-deg half-angle. Each directional proton energy channel was sampled once every 3 min, each of the two omnidirectional proton detectors was sampled once per min, and each of the electron energy channels was sampled once every 2 min. Accumulation times exceeded the spacecraft spin period. The experiment operated throughout the spacecraft life. NSSDC has all the useful data that now exist from this investigation.
