✦ Synopsis

This Paper summarizes and correlates the liquid helium pump data obtained previously in two separate test programs, In normal helium the second set of data shows a large performance improvement over the first set as a result of changes in measurement methods and in the pump itself. Peak pump efficiencies of 46% were measured. The pump appeared to perform approximately the same in He II as in He I; however, the He II data are not adequate for system design or analyses. Therefore, a new pump test program is planned to test the improved version of the pump in an apparatus designed specifically for He II.

It should be noted that the mesh regenerators used in Reference 1 achieved a minimum temperature not lower than 40 K and a net refrigeration power of ~ 3 W at 77 K. On the contrary, our experimental data have shown that the single stage regenerator, suitably hybridized, can attain minimum temperatur
