The Radiation-Monitoring Complex of the СПРУТ-VI System

The radiation-monitoring complex of the СПРУТ-VI system was installed on board the Mir orbital station and used to study the fine structure of the Earths inner radiation belt in low and near-equatorial latitudes. The complex comprised a system of gas-discharge counters, as well as electron and proton spectrometers. The range of measured energies was 0.1–2.0 MeV for electrons and 0.1–10.0 MeV for protons. The possibility of changing the work program of the complex under spaceflight conditions was provided for.

GRIF-1 experiment on board the SPEKTR/MIR orbital complex: Study of solar X-ray, gamma-ray, and neutron flares and correlation of magnetosphere-charged particle fluxes with solar activity

The SPEKTR module of the MIR orbital station was launched in May 1995. The multipurpose experiment was based on the GRIF-1 research complex consisting of an oriented X-ray spectrometer, a spectrometer of gamma-quanta and neutrons, a spectrometer of electrons and protons with a large geometrical factor, and a spectrometer of electrons, protons, and nuclei with a small geometrical factor. The solar geophysical aspects of the experiment included the measurements of spectral and temporal parameters of solar hard electromagnetic (0.01–50 MeV) and neutron (>20 MзB) radiation, the study of spectral, temporal, and spatial characteristics of energetic electrons (0.04–1.5 MeV), protons, and nuclei (1–200 MeV/nucleon) in the circumterrestrial space, as well as the correlations of these parameters with solar activity phenomena.
