Cryogenic Testing at the SSC String Test Facility
A multipurpose cryogenic testing facility was constructed and became operational in 1986 at Fermilab. It consists of a standard Tevatron satellite refrigerator and 450 liter subcooling dewar housed within a building adjacent to a Tevatron refrigerator. A 11 m by 15 m high bay contains power supplies necessary to power Superconducting Super Collider (SSC) magnets, a cryogenic feedcan to interface the refrigerator to the magnet string, and an area for testing Tevatron components. Currently, a 120 m, 4 m diameter tunnel has been constructed off the high bay to house a half cell of SSC Design D magnets. Capabilities have made to extend the tunnel up to 1 km in length.
Testing at the facility includes: SSC long string test, heat leak measurement, cold compressor tests, turbine test, and cold leak checking.
