Abstract

The Large Hadron Collider (LHC) will need some 800 superconducting magnets to correct the orbit of the particle beams. These magnets will be individually powered and each needs a pair of current leads to the ambient temperature. To minimize the heat loss through these leads, the magnets have been designed for a very low current of about 25 amperes and the leads could be made with high T/sub c/ material. A theoretical study by the authors (see Adv. Cryog. Eng., vol.39, 1994) investigated different types of high T/sub c/ leads. Since then, a prototype has been built which combines a low heat loss with an extremely simple design. The design, the test set up and the results are described in this paper.<>
