An improved cryostat for use in a low or a substantially gravity-free environment adapted to cool an experiment through the use of helium II, or helium in its super fluid state. The cryostat is characterized by a plurality of interchangeable daughter dewars and helium supply or mother dewar having connected therewith a low pressure venting system for converting helium I contained therein to a super fluid state for use as a primary cryogen. Each daughter dewar is adapted to be removably mounted in mated relation on the mother dewar and is characterized by...
An improved cryostat for use aboard a spacecraft in a gravity-free environment comprising: A. a mother dewar having an inner vessel confining a primary cryogen in a liquid state, a tubular thimbal extended thereinto, and means for cooling said primary cryogen at low pressures of celestial space including a vent connected with a porous plug communicating with an external surface of the spacecraft; and B. a plurality of serially useable daughter dewars, each having an experiment package mounted therein and confining a secondary cryogen for cooling the expe...
