摘要：

We describe the design, operation, and performance of a light-weight, long-hold-time He-3 cryostat used to cool the bolometric detectors of a far-infrared radiometer. A small internally pumped He-3 reservoir, supported by He-4 and liquid-nitrogen baths, is maintained at 0.25 K for more than a week. The cryostat has a total volume of 30 l and weights 10 kg.
