In recent space development, the use of small satellites incorporating commercial off-the-shelf (COTS) components has been increasing. However, evaluating the radiation tolerance of such devices, particularly their susceptibility to single event effects (SEE) induced by low linear energy transfer (LET) charged particles, remains an issue. In this study, a low-LET charged particle irradiation field simulating the low Earth orbit (LEO) environment was constructed using the 1 MV Pelletron accelerator at Tohoku University. To enable precise control of the number of irradiated particles over a wide flux range, an indirect measurement method using scintillation light was developed in addition to conventional current measurement and particle counting techniques.
