【 摘 要 】

Superconducting magnets cooled with cryocoolers become more and more attractive due to an increasing cooling performance and decreasing costs. This cooling mode offers new perspectives to high field magnets like the possibility to be installed where space is limited and the use in rotating systems. At the Paul Scherrer Institute (PSI), two projects involving superconducting magnets cooled with cryocoolers are ongoing: a compact 6 T super-bend for the upgrade of the Swiss Light Source has been designed and a concept for a new generation of proton therapy gantries for cancer treatment was proposed last year. This contribution focuses on a dedicated compact and adjustable test stand in construction at PSI aiming at the thermal, mechanical and magnetic characterization of future superconducting magnets cooled with cryocoolers under operating conditions.
