Outline of Final Research Achievements

Using the data obtained by FPI-DIS (Fast Plasma Investigation-Dual Ion Sensor) that the research team lead developed, the electron scale structure of the dayside magnetic reconnection in the Earth’s magnetosphere was revealed for the first time. The research team also succeeded in developing a new low energy charged particle spectrometer that can measure both ions and electrons with high time resolution that will be first flight verified by SS-520-3 ISAS Sounding Rocket Experiment in December 2017.
