Abstract
A description of the design and operation of the low temperature laboratory recently built at Yale University is given. The equipment consists of a Kapitza type helium liquefier and associated helium gas storage and circulation systems. The design and performance of the expansion engine of the liquefier is discussed and those details most important to successful operation are stressed. The size and arrangement of the heat exchanger coils are next discussed and a table of tube sizes given. The lay‐out of the helium distribution and purifying system is given including a description of the type and performance of the compressor and vacuum pumps. Finally figures are given on the over‐all efficiency of the plant, including the starting up time, the amount of liquid air consumed and the hourly rate of production of liquid helium.Keywords
