Abstract
A closed-cycle helium refrigerator with a 3-kelvin station has been built and tested. A 200-mW net refrigeration capacity was demonstrated at 3.1 kelvins. The system has been operated continuously for 1200 hours with no detectable degradation of performance. Reduced refrigerator temperature (from 4.5 to 3.0 kelvins) will increase the available gain and bandwidth, and reduce the noise temperature of microwave masers.
