ABSTRACT:
An apparatus for delivering current to a cooled electrical device. The apparatus includes at least one electrical line having a first end at a first temperature and a second end at a second temperature being lower than the first temperature. The second end is provided for connection to the cooled electrical device to deliver current to the cooled electrical device. The cooled electrical device is preferable a superconducting device. At least a portion of the electrical line includes a part of a cold head. The part of the cold head is preferably a regenerator or a pulse tube of a pulse tube cooler.
