Developments of new techniques for particle detectors with wide energy range and with high angular resolution are needed in the future plasma universe exploration mission in order to resolve mechanism of particle acceleration in suite observation. In this study, we developed new APD for middle energy electron (5-35 keV) and new Si strip detector with very thin dead layer to detect lower than 10keV electrons. The sensor technologies under high radiation environment are established using pixel and strip detectors developed by this study.
