Abstract

We describe a4He cryostat suitable for cooling a large (about 50 1 in volume) multiband bolometric photometer for mm-waves. The cryostat features two large optical windows and a hold time longer than 2 weeks. The long hold time has been obtained using a 20 K vapour cooled shield for the liquid helium tank and superinsulation for the nitrogen tank. The tanks are supported by kevlar cords. The cryostat has been optimized for operation on long duration stratospheric balloon flights, and has been tested successfully at ground level and on two short balloon flights.
