โœฆ Synopsis

When using various cryogenic devices in balloons, aeroplanes, and artificial earth satellites, in which gases from the cryostat are discharged into outer space, it is often necessary to maintain the working pressure in the cryostat at a given level, independent of the pressure of the surrounding medium.

The design of a continuous flow helium cryostat is described for optical studies with an optical fixed high-pressure chamber in the temperature range from 4 to 300 K. The liquid helium consumption for 4 K is 21 h-', and less than 0.5 1 h-'for temperatures above 20 K.
