Résumé

An electrically insulated pulse-tube cooler head was designed and tested as the current lead for the superconducting magnet. One pair of the cooler head is driven by the four-valve method. Each cooler head operate with out of phase to reduce the pulsation of the compressor. The plastic tubes are used for the connecting line to the rotary valve. Oscillating frequency of 1.5 Hz has been tested under the mean driving pressure of 1.5 MPa. The cooling capacity at 65 K was 74 watts in total and current of 850 A was able to supply in stably.
