ESR’s has 19 vacuum chambers, ranging from 150mm diameter to 1m diameter with typical test temperatures within the range -50°C to +80°C. However, this temperature range can be widened for particular projects such as BepiColombo or JWST where temperatures of +400°C and cryogenic testing down to 20K were achieved. While most chambers are configured for the testing of mechanisms and components such as bearings and gears, they can easily be configured for general thermal vacuum test use.
