Description
Based on the existing JT60SA Toroidal Field Coils Cryogenic Test Facility, improvement and new elements have been integrated to make a new platform named MATTRICS (MAgnet Technology Testing InfrastruCtureS) in order to test a wide range of superconducting magnet technologies. The facility is supplied by a helium refrigerator with a capacity of ~490 W at 4.2 K. One main specificity of the cryostat is its huge space that can welcome magnets on a scale of a few meters. A power supply at 25.7 kA and a Magnet Safety System (MSS) enable safe tests of high energy magnets (~100 MJ), coupled with an instrumentation and acquisition system to study quench propagation. The development of new conductors based on REBCO tapes for high current, high field magnets will make a great use of the test station’s versatility, for instance in the framework of the Suprafusion project. After a summary of the performance of MATTRICS, the latest studies and adaptations of the test station regarding the requirements for REBCO magnets are presented. The simulations has been carried out using Simcryogenics, the CEA tool dedicated to cryogenic systems dynamic modeling.
