The fast alternative cryogenic experiment testbed

摘要

Subsystems for a "proof of concept" cryogenicpayload have been developed to demonstrate the ability toaccommodate low temperature science investigations within theconstraints of the Hitchhiker siderail (HH-S) carrier on the SpaceShuttle. These subsystems include: a hybrid solid neon- superfluidhelium cryostat, a multi-channel Versa Modular European (VME)architecture Germanium Resistance Thermometer (GRT) readoutand heater control servo system, and a multiple thermal isolationstage "probe" for thermal control of helium samples. The analysisand tests of these subsystems have proven the feasibility of acryogenic HH-S carrier payload. 2000 Elsevier Science Ltd. All rights reserved.
