Abstract

Porous plugs were used as thermomechanical pumps to transfer helium II from one dewar to another through a transfer line and two valves. Two different sizes of porous plugs were used, and a scanning electron microscope image of the plugs is presented. Eighty litres were transferred at a maximum flow rate of 90 L/hr. Temperature, pressure, flow rate, and heater power data are presented and compared to a theoretical model.
