Abstract

A single-stage pulse tube cryocooler has been designed and fabricated to provide cooling at 50 K for a high temperature superconducting magnet. Sage software was used to design the pulse tube, with a predicted 25 W of cooling power at 50 K, and an input indicated power of 1.7 kW. The fabricated pulse tube is closely coupled to a metallic diaphragm compressor (pressure wave generator) with a 60 ml swept volume, operating at 50 Hz, and with a mean helium working gas pressure of 25 bar. Details of the development, experimental results and correlations to the Sage model are discussed.
