โœฆ Synopsis

Main parameters of the cryogenic current lead for a 1.2 kA cable-in-copper conduit conductor ("twist in tube" ) type are described in this paper. It is cooled by gaseous forced-flow helium in laminary regime. The criteria and the sequence of this current lead optimization are determined.

The results of the optimal parameters definition are presented.

The optimal operation conditions are found.

Large superconducting apparatus are best cooled by directly coupled refrigerators. The input of high currents to the superconductors produces heat losses according to the Wiedemann-Franz law. It is well-known that the direct input losses can be reduced when the leads are precooled over their entire
