抜粋

The CALorimetric Electron Telescope (CALET) mission has been proposed to measure electrons and gamma rays in a wide energy range on the Japanese Experiment Module (JEM)/International Space Station (ISS) and the development is being carried out successfully. CALET has a large geometric factor that makes it possible to continuously and precisely measure electron intensities, and can provide statistically sufficient data for GeV energies, though the low energy measurements will be performed in a restricted time period and are severely restricted by ISS orbits. The purpose of the CALET mission pertaining to solar physics is to get new information on the cosmic ray transport in the heliosphere. We estimate the energy dependence of the diffusion of electrons through the solar magnetic field. Further we simultaneously observe electrons and protons in the 1- 10 GeV energy range and investigate the charge sign dependence of solar modulation. We also discuss some expectations in different solar polarities, using a correlation between the cosmic-ray intensity and the neutron monitor counting rate. For short-term measurements, we expect to detect several Forbush decreases in electron flux. In such decreases, shortterm variations of negative charges might differ from those of positive ones.
