Summary

This paper reviews recent advances in single- and multi-stage Stirling-type pulse tube cryocoolers (SPTCs) in the authors’ laboratory, in which single-stage coolers operate at 30–200 K, two-stage ones at 15–100 K while three- and four-stage ones cover 2–10 K. Single-stage coolers involve micro, miniature and middle-size ones, with cooling capacities varying from 1.0 W to 50 W, are for cooling infrared and optical devices. Recently high-capacity ones with 750 W at 77 K are developed to cool high-Tc superconducting facilities such as cables and magnets. Two-stage SPTCs are for simultaneously providing cooling at both stages.
Three-stage SPTCs are developed to achieve cooling at around 10 K while four-stage ones do at below 4 K. Both can also precool J-T coolers to achieve lower temperatures for low-Tc superconducting devices and for deep space exploration. The designs of the SPTCs including the compressors are described in which the efforts in enhancing the efficiencies are emphasized.
