Abstract :
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. The aim is to deliver a direct current of 13 kA into a 4.5 K liquid helium bath with a total heat load of less than 1.5 W. These hybrid leads transport the current via a resistive heat exchanger cooled by a separate source of helium gas in the high temperature region, and below 50 K via self-cooled high temperature superconductor.
