Closed-cycle neon refrigerator for high-temperature superconducting magnets.

Author(s) : BLUMENFELD P. E., PFOTENHAUER J. M.

Summary

The refrigerator is intended for use in testing small superconducting magnets formed from BSCCO and other high-temperature superconducting materials. A hybrid design is used, with a helium cryocooler operating on the Gifford-McMahon cycle precooling a separate neon stream, which is driven by a rotary vane compressor that provides a flow rate of 0.4 gramme/second. The refrigerator is designed to provide a cooling capacity of 10 watts at 25 K. At the cold end, the neon will be partially condensed into a two-phase fluid which is transferred out of the refrigerator vessel to a separate magnet test vessel.
