Abstract:

The results of the reduction and analysis of data obtained from instrumentation flown on the Air Force Satellite Hitch-hiker I 1963-25B are presented. The instrumentation included two electrostatic analyzers one for electrons, 15 to 100 kev, the other for protons, 15 to 100 kev a scintillation spectrometer for electrons, 0.7 to 4.0 Mev a phoswich scintillation spectrometer for protons 1. to 5. Mev and 7.5 to 120 Mev and a Geiger counter electrons greater than 4. Mev, protons greater than 40. Mev. Detailed data on integral energy spectra, pitch angle distributions, and perpendicular unidirectional intensities, as functions of B, Lor lambda, L and time are given in five papers appended to this report. No substantial intensities of protons, 15 to 100 kev, were observed. Electrons, 15 to 100 kev, were observed with intensities as great as 2 x 100lllsq cm-sec-ster-kev at 40 kev, but the anomalous angular distributions obtained cast doubt on the credibility of these data. Peak inner belt intensities for electrons above 1 Mev were about 5 x 100, 000 electronssq cm sec ster at L approx. 1.6.
