Polar Earth Orbit（PEO）Chamber(Electron Beam・Plasma Environment)
This chamber has an electron beam gun and plasma source to simulate the particular environment such as PEO.
To operate the electron beam gun and plasma source at the same we can simulate the aurora zone environment.
Separately operating each system can create GEO or LEO environment.
In addition to charging and arcing test of spacecraft, PEO chamber is used in the verification test of MUSCAT and the basic research of spacecraft charging.
