Conceptual design and analysis of a cryogenic system for a new test facility for high temperature superconductor current leads (HTS CLs)

In view of the R&D; program on HTS CL at EPFL-CRPP PSI Villigen it is foreseen to extend the capabilities of an existing facility (JORDI) in order to be able to perform tests of HTS CL in different conditions. The present work is focused on the conceptual design of the cryogenics needed for the facility upgrade considering the requirement of an as extended as possible range of operation. Two cooling options for the copper part of a CL are considered. The use of heat exchangers for the optimization of the cryogenic system is discussed and their size is assessed.
