Sumario:Cryogenic Ltd. and ENEL S.p.A. have collaborated on the design and construction of prototype current leads for the large hadron collider project at CERN, Geneva. This delivers a current of 13 kA into a 4.5 K liquid helium bath with a total heat load of 1.5 W. These leads transport the current via a resistive heat exchanger cooled by helium gas in the high-temperature region, and below 50 K via self-cooled high-temperature superconductor. (3 refs).
