Summary

A NEW COMPACT CRYOGENIC COLD COMPRESSOR WAS DEVELOPED IN ORDER TO PRODUCE SUPERCRITICAL HELIUM BELOW 4.2K FOR DEMONSTRATION POLOIDAL COILS (DPC) WHICH ARE FORCED-FLOW COOLED TYPE SUPERCONDUCTING PULSE COILS. THE COLD COMPRESSOR EFFICIENTLY REDUCES PRESSURE IN A 3,000 L LIQUID HELIUM BATH DOWN TO 50 KILOPASCALS. CONSEQUENTLY, SUPERCRITICAL HELIUM DOWN TO 3.5 K IS PRODUCED AND SUPPLIED TO THE DPC COILS. THE COMPRESSOR WAS OPERATED FOR 220 H IN A SATURATED CONDITION FROM 50 TO 100 KILOPASCALS, WITHOUT ANY FAILURE. HIGH ADIABATIC EFFICIENCY (MORE THAN 60%) IS ACHIEVED WITH WIDE FLOW RANGE (25-65 G/S) AND THE DESIGN VALUE IS FULLY SATISFIED.
