Title: Experimental Investigation on a Single-Stage Stirling-Type Pulse Tube Cryocooler Working below 30 K

Abstract: Stirling-type pulse tube cryocoolers are promising candidates for space application and for cooling HTS devices. Nevertheless, most single-stage Stirling-type pulse tube cryocoolers (SSPTCs) are unable to reach a cooling temperature below 25 K. In this article, an in-line type SSPTC driven by a linear compressor was designed, fabricated and experimentally investigated. By optimizing the operating conditions, the cryocooler has reached a no-load refrigeration temperature below 34.2 K at 35.2 Hz without the double-inlet phase shifter. However with an optimum double-inlet opening, the cryocooler has reached a no-load refrigeration temperature of 24.7 K and can provide a cooling power of 1.3 W at 30 K when the electric input power to the compressor is 205 W.
