Heat Transfer in the LHC Main Superconducting Bus Bars

CERN is performing a systematic analysis of the interconnecting bus bars of the Large Hadron Collider (LHC) main magnets. Their thermal, electrical, mechanical and hydraulic performances are addressed. In the frame of these studies, the heat transfer between the main superconducting (SC) bus bars and the surrounding He bath is investigated. It represents a key parameter in the comprehension of the bus bars stability and quench propagation mechanisms, thus crucial for the analysis of the 2008 incident which was triggered by a defective bus bars joint. This paper reports on the experimental tests and relative analysis aiming at describing the thermal behavior of the LHC main bus bars.
