The XVC test facility was developed for the exposure of components to thermal vacuum conditions, representing space environment in open space and sun exposure. Furthermore, the thermal vacuum bakeout and the thermal vacuum cycling of flight hardware are key applications for this test facility.
The vacuum chamber is made of stainless steel and offers an inner space of approx. 1,500 mm in width, 1,500 mm in height, and a length of 2,000 mm (volume: approx. 4,5 m³). Therefore, the test facility is suitable for testing larger sub-elements and components.
The temperature of the hardware under investigation is adjusted by means of temperature-controlled copper plate(s) mounted inside the vacuum chamber, and by additional wall/door/ceiling heaters. Process plates are heated electrically, the cooling is performed by liquid nitrogen (LN2: T = -196 °C).
The XVC test rig is attached to a clean room classified as ISO7.
