Mission Name: Injun 4This experiment was designed to measure precipitating and trapped particle fluxes. Four CdS-type particle detectors were used for this purpose, one at a pitch angle of 90 deg, one at 125 deg, and two at 160 deg (one with and one without a magnetic deflection within the entrance aperture). Orientation was referred to the direction of the local magnetic field line such that 0 deg corresponded to a detector looking downward towards the earth in the northern hemisphere. The detector accumulators were sampled sequentially every 8 s. The detectors were flown to yield total flux measurements for electrons (E>100 eV) and protons (E>100 eV). Extremely high background counting rates encountered during the flight hindered analysis of the data.
