| Research Abstract |
We developed ELF (ELectron-emitting Film) to mitigate spacecraft charging. ELF is film made of fluoro-polymer coating over etched copper plate. The coating is to make electron field emission in a passive manner utilizing the charging of the coating due to energetic electrons in orbit. We carried out on-orbit demonstration of ELF onboard a nanosatellite, HORYU-II, that was launched to 680km polar orbit. We confirmed charging of the fluoro-polymer and the electron emission current up to 6μA over the aurora zone.
