摘要：

Compared to the instability in some double-inlet pulse tube refrigerators due to the DC-flow in the cooling system, the single orifice pulse tube refrigerator (OPTR) is usually considered to operate stably. However, in recent experiments we found a new phenomenon in form of a temperature hysteresis in a single stage GM-type OPTR that depends on the heat load and on the adjustment of the needle valve connecting the pulse tube warm end with the buffer volume. The lowest temperature of this cooler, when operated on a 6 kW compressor, was 18.8 K with double inlet and 30.4 K with single orifice.
