HTS Prototype Coil Design and Modelling for Radiation Hardness Experiments

The Ring Cyclotron at the Paul Scherrer Institute (PSI) produces the highest average power proton beam in the world with a fixed beam energy of 590 MeV. Currently, all beam lines magnets are resistive, but superconducting magnets, in particular High-Temperature Superconductors (HTS), could be a viable alternative to increase the overall machine performance and to reduce the energy consumption. Understanding how high-energy particles affect HTS materials for their use in high-radiation environments is, thus, mandatory, before moving in the direction of using HTS magnets. To study these phenomena, an HTS demonstrator magnet placed close to the ring cyclotron for monitoring the evolution of the superconducting properties as close as possible to operating conditions, is under construction. In this paper, the design of experiment and preliminary tests towards the construction of the demonstrator magnet for the irradiation experiment are reported.
