Abstract

In the SSC main collider up to five orders of superconducting corrector magnets will be incorporated into the spool pieces to correct for component and machine aberrations. Each order of corrector magnet will be separately powered. This will require a corrector element power lead (CEPL) with a single, room temperature-to-4K interface with multiple leads. CEPLs represent a potentially significant heat load to the 4K helium and must be vapor-cooled to meet heat leak requirements. Analysis and design of vaporcooled power leads for cryogenic systems have been extensively documented in the literature 1,2. The purpose of this paper is to focus on the requirements and associated issues for this particular application.
