We are developing Ionic liquids electrospray thruster (ILEST) for new thruster which can be mounted on nanosatellite. In ILEST, ionic liquids are used for propellant. It gains thrust by being applied voltage and extracting ions. To fabricate two-stage electrodes for getting adequate and stable thrust, we are working glass through-hole dry etching with Ni electroplated as a mask.
This is a collaborative research with Yokohama National University.
