Bake Out facility is installed in a permanent ISO8 cleanroom. The chamber is equipped with a Thermolectric Quartz Crystal Microbalance (TQCM) to monitor outgassing. TQCM data are processed to validate bake out completion as per ESA guidelines and ECSS-Q-ST-70-01C. A liquid nitrogen temperature cold trap will limit outgassing redistibution during the bake out process. Particulate and molecular contamination witnesses are available on request.
To optmize harnesses and MLI blankets outgassing, the chamber is fitted with a shelves modular system.
Chamber repressurization can be controlled to fulfill ESA's recommendation of a <20mbar/min slope.
Pressure, temperature and TQCM data and analysis are provided to customer.
