Design and Development of multiple space particle energy spectrum analyzer

The multiple space particle spectrum analyzer has been proposed as the scientific payload of the Formosat-8C satellite (FS-8C). This multiple space particle energy spectrometer is a small, low-weight, low-power consumption advanced analyzer. Its design was originally derived from the STE (Supra Thermal Electron) detector on the STEREO satellite. This analyzer uses an evolved a multi-channel detector component, which can measure electrons and ions in the energy range of approximately 1 ~ 200 keV, and can establish high-energy neutral atom imaging, hoping to provide information to the space science community more valuable data. The prototype of this payload has been initially produced, and it can comply with the overall interface specifications of the FS-8C, including a size of < 2U, a weight of < 5kg, an average orbital power consumption of less than 2W. We expect to complete the delivery of the flying model in September 2026 according to the schedule.
