There are several works 1-6 on thermal analysis of liquid helium dewars and attempts to reduce the evaporation rate of the dewar. However, at present, an accurate analytical study may not be possible due to the radiant heat input by "funnelling; down through the neck tube. /n this work, the radiant
A novel application of gas oscillation in a tube connected between room and liquid helium temperatures is described. The apparatus is designed to increase the internal pressure in a liquid helium storage vessel, in order to transfer the liquid from the storage vessel to an individual cryostat. The a
Experimental equipment for pressure control and evaporation rate measurement of a low-loss helium cryostat is described. The dependence of the helium gas outflow on the linearly varying pressure is presented for an NMR cryostat. The variations in measured helium evaporation rate were significantly h
