Summary

The regenerator material erbium-nickel(0.9)-cobalt(0.1), the cold end of the second cylinder made on copper, and intake/exhaust valve having original timing and interval are used in the cryocooler. In the study, four sizes of cylinders and two types of compressor units were prepared and the cooling capacities were measured. The maximum cooling capacity of the first stage at 40 K was 53.7 watts and that of the second stage at 4.2 K was 1.74 watt.
