Low Earth Orbit（LEO）Chamber (Plasma Environment)
This chamber has a plasma source to simulate the plasma environment in LEO.
The plasma source is non-electronode and is the same model plasma source that was mounted on HAYABUSA.
Many charging tests for sattelites have been conducted in the past.
LEO chamber is also being used for basic research and development related to spacecraft charging and arcing.
