Radiation measurements on the ''Kosmos-900'' satellite

Considered is the design and principle of operation of differential electron spectrometers positioned on the ''Kosmos-900'' satellite. Spectrometers are intended for detection of electron of the energy from 30 to 1600 keV with the help of semiconductor diffusion-drift silicon detectors placed in bending magnet systems with angular deviation of 180 deg. Presented are preliminary results of measuring electron fluxes on the ''Kosmos'-900'' satellite orbit. Spectrometer channel calibration has been made with the help of electron and γ sources. The results of determination of spectrometer efficiency are presented. Presented also are the differential energy spectra of electrons obtained in radiation Earth belt in magnetically calm period of 7.06 1977, 03sup(n)59sup(m)-04sup(n)0Ssup(m)
