Abstract This paper describes the performance measurements of a pulse tube refrigerator (PTR), originally developed for cooling cryo-surgical probes (CryoPens) to about 180 K for dermatological applications. The linear compressor, which has a maximum swept volume of 3.9 cc, was instrumented to measure the piston position with a laser position sensor shining through a sapphire window on one end of the compressor. These results along with pressures measured at the reservoir, pulse tube, and compressor allowed us to determine the flow and PV power at various, locations, which were then compared with the predictions from our models. Comparisons were also made between the calculated and measured thermal load curve. The cooling rate for insertion of warm CryoPens was measured and the resulting thermal load on the PTR was determined, which agreed well with calculations.
