Summary

A cryostat including a helium-3 refrigerator has been designed, built, coupled to a multiband far infrared photometer and successfully operated on a balloon flight. The paper describes the cryostat, which is able to cool three bolometers to 0.3 K and one to 1.5 K. The total holding time of the cryostat exceeds 5 days, being limited by exhaustion of the main helium 4 and nitrogen baths. The autonomy of the helium-3 cryostat is more than 50 hours, and the recycling time is about 3 hours. The performance of the system in the ARGO 1993 flight is also reported.
