IIR documentSummary
A single-stage pulse tube cooler (PTC) was developed at Zhejiang University. A lowest no-load refrigeration temperature of 11.1 K was achieved with an actual input power of 6.7 kW. The cooler obtained cooling capacities of 17.8 W at 20 K and 39.4 W at 30 K, which makes it competent to substitute the conventional G-M cooler for cooling superconducting magnets in the temperature region of 20 to 40 K. A long-term operation test with a heat load of 48.5 W was carried out and the repeatability of cooling performance was also checked. The results show that the PTC works stable and reliable.
