Summary

This apparatus makes use of a closed-cycle refrigerator attached to an insulated cold finger inserted into a conventional stainless steel dewar to liquefy a quantity of neon gas stored previously in a tank. Starting with a dewar holding a small coil that had not been precooled, and using a refrigerator with rated cooling capacity of 15 watt at 26 K, approximately 0.5 litre of liquid neon was condensed into the dewar in about 4 hours. The apparatus has been used to measure the critical currents of high-critical temperature oxide tape coils both with and without the application of an external magnetic field.
