Abstract
Recent advances in the performance of pulse tube refrigerators (PTR) make them attractive for cooling purposes in HTS applications. A major advantage is the significant reduction of vibration at their cold stage. This paper gives some examples, in which pulse tube coolers have been used to cool supercconducting components: 1) Low noise cooling with a single stage pulse tube cooler of a) a high-Tc-superconducting antenna for MRI and b) a high-Tc SQUID system; 2) Use of a two-stage pulse tube refrigerator capable of reaching temperatures in the liquid 4He range to operate a conventional superconducting Nb3Sn magnet. The magnet was driven with 120 A, BSSCO current leads being employed between the first stage of the cooler and the magnet for low thermal conduction.
