Mission Name: IMP-IThe solar proton monitoring experiment consisted of five separate detectors, each using one or more solid-state detector elements. Three detectors, each with a 2-pi-sr field of view and a 5.12-s accumulation time, measured protons with energies greater than 10, 30, and 60 MeV. Resultant hourly averaged fluxes were published on a rapid basis in "Solar-Geophysical Data." The fourth detector, a two-element telescope, measured directional fluxes of protons in the energy intervals from 0.2 to 0.5, 0.5 to 2.0, and 2.0 to 7.5 MeV and directional fluxes of alpha particles in the energy interval from 8 to 20 MeV. The fifth detector measured directional fluxes of electrons above 10 keV. For the last two detectors, counts were obtained in 45-deg sectors as the spacecraft spun. Onboard calibration capability for the first four detectors was included.
