- Abstract
- In this paper, the correlation of the Earth’s Radiation Belts electron doses in low near-Earth orbit behind a small shield with the average indicators of the Earth’s magnetosphere state during periods of geomagnetic disturbances is shown and analyzed. The results of the “Expose-R2” experiment on the ISS and “DEPRON” on the “Lomonosov” satellite (SINP MSU) are considered. In the “Expose-R2” experiment on the ISS, the absorbed dose behind the shield at 0.6 g cm was measured every 10 seconds. In the “DEPRON” experiment, the absorbed dose behind the shield at 0.45 g cm and 0.81 g cm was measured every second. Due to a large number of measurement gaps in the “DEPRON” experiment, a procedure for restoring the experimental data is proposed. Based on the data obtained, correlations between the average daily absorbed dose rate and various cosmophysical indices in fixed ranges of -coordinate variations (the McIlwain parameter, at the geomagnetic equator equal to the distance to the Earth’s center in Earth radii) are considered. It is shown that after geomagnetic disturbances, the linear regression coefficients between the absorbed dose rate and the considered geophysical indices have a uniform dependence on the -coordinate. For magnetic storms with < 100 nT, the dependences of the linear regression coefficients on the -coordinate are well approximated by a normal distribution up to = 4.7. The average value of the maximum position = 4.10 ± 0.15, standard deviation σ = 0.40 ± 0.07. For magnetic storms with > 100 nT, the distribution maximum shifts to = 3.0 and σ = 0.22.
