Abstract
Current leads supply electrical current to high-field superconducting magnets, operating at low temperatures. The heat leak flowing down the current lead must be intercepted and extracted. In the present work, we consider different methods of intercepting this heat, along with the refrigeration power required for each method. The cooling methods studied include envelope cooling, wherein the coolant flows parallel to the lead, and helical coil cooling, in which, a coolant channel is wrapped around the lead.
