摘要：

We report the design, space-qualification and flight performance of a He-3 refrigerator that has achieved the first sub-Kelvin temperatures in orbit. The refrigerator has been used to cool the bolometric detectors of the Far Infrared Photometer (FIRP) on the Infrared Telescope in Space (IRTS). The refrigerator has no moving parts, and can be re-cycled indefinitely in zero-g with > 95% duty cycle using simple control electronics. It provides 10 mu W Of cooling power at T < 310 mK with less than or equal to 2 mW average power dissipation to a 2.0 K heat sink for about 10 days. (C) 1998 Elsevier Science Ltd.
