In order to satisfy the cooling demand of high temperature superconducting devices, the theoretical calculation, structure design and refrigeration performance test in 40 W/30 K single stage G-M cryocooler with large refrigerating capacity have been carried on in this paper. By using the composite regenerative material consist of phosphor bronze mesh and lead ball, the test result indicated that the prototype of G-M cryocooler can obtain a lowest refrigeration temperature of 19.2 K and offer a refrigerating capacity of 38.8 W in 30K, and it has been basically accorded with the design goal.
