Hall thrsuter
Hall thruster is promising propulsion system for future space missions. Electrons are supplied from a cathode outside and trapped into discharge channel. Those are electrically heated up and generate ions by ionization collision, and ions are accelerated electrostatically. Since this thruster can have higher thrust density than ion thrusters, its usage is on missions such as orbit raising, trans-orbit behicles, and so on. My interest is in developing sophisticated, erosion-free thruster to expand usage of this thruster.
Measurement equipments
Plasma generation and acceleration is characterized by some kinds of equipments. I'm strongly interested in improvement those materials and clear understanding of plasma in the thruster. Currently I also engage to develop/improve equipments. Accurate thrust measurement, plasma measurement method to know inside/outside plasma condition, or fundamental electric apparatus are the examples.

Other topics
Mainly I'm engaging to experimental things, but I hope I could expand my fields. The other things are under learning, such as computation that can be useful for designing Hall thrsuter. New topics will be added near future.
