Design of cryogen-free operation of an HTS filter subsystem with co-axial pulse tube cryocoolers.

Author(s) : JU Y. L., YUAN K., HOU Y. K., et al.

Summary

In view of the present trend of developing high frequency Stirling type pulse tube coolers with large-scale cooling capacity at liquid nitrogen temperatures for cooling of HTS RF filters for wireless telecommunications, the authors report on system design of Stirling type co-axial pulse tube cryocoolers (PTCs) for the purpose of developing a fully integrated, cryogen-free operation of HTS RF filter subsystems. Two different co-axial cold finger geometries of single-stage and two-stage pulse tube coolers are proposed, analysed and designed. The design objective of the coolers is for 3.5 W of cooling capacity at 65 K with a specific power of 30 W/W.
