Summary

A compact one-shot helium 3 cryostat was manufactured for use as an X-ray detector at a temperature of 0.4 K. The cryostat employed 2 valves: one for controlling a charcoal adsorption pump, and the other for facilitating liquid helium handling. The use of 2 valves made it possible to decrease the amount of liquid helium, including the transfer loss. Superconducting thin wires with a very low copper ratio were useful for generating a magnetic field of moderate strength, while suppressing the heat flow into the cryogenic region.
