Experimental Setup 01 GEO chamber

Geostationary Earth Orbit (GEO) test chamber (electron beam environment)

GEO chamber

<GEO chamber>

This vacuum chamber has an electron beam gun to simulate high energy electron in the GEO environment. In the past, charging tests for many sattelites have been conducted in GEO chamber. In addition, GEO chamber is being used for basic research and development related to spacecraft charging and arcing.
