Research Field(Keyword & Summary)
  1. Space charge measurement, Quantum chemical calculation, Dielectric phenomena, Radiation effect on dielectrics, MEMS technology for sensor fabrication

    I focus in the dielectric phenomena on spacecraft materials. The outside layers of spacecraft are mainly made of dielectric materials. Since those materials are continually exposed in space environment with high-energy radioactive rays such as electrons and protons, these charged particles are injected and accumulate in those bulks. A partially enhanced electric potential distribution on the surface of the spacecraft is induced due to charge accumulation. Sometimes it leads a discharge and gives a serious operation anomaly. Therefore, it is necessary to investigate the effect of the dielectric phenomena under radiation condition. So, we developed the measurement system and sensor.
