Abstract
Demand flow cryostat 10 has an expansion nozzle 24 from which flow is controlled by valve needle 32. Bellows 34 regulates flow to maintain substantially constant temperature in the cooled space adjacent interior surface 26. Guide tube 38 and felt 44 control flow of the mixed liquid-vapor cryogen to stabilize temperature at the electronic device 30 which is cooled by the cryostat.
