Abstract:

This paper describes the development and testing of a large neon cycle cryogenic pump for use with a low density wind tunnel meant for both ionized and non-ionized flows. The development work necessary in the choice of the refrigerant cycle and the production of the required hardware is described in some detail. Once the cryogenic pump was in operation it was thoroughly tested both as a refrigerator system and as a pump. Experimental data on the thermodynamic properties of neon was obtained and found to be in excellent agreement with the available theoretical data. The refrigerator cycle was found to operate satisfactorily and as predicted. The pump itself was found to operate satisfactorily and as predicted over its entire designed range of operation. A pumping rate of 0.8 grsec N sub 2 was achieved while maintaining the test section pressure in the 1 - 4 x 0.001 torr region. Author
