【タイトル】 The Advancement and Qualification of the HTS Magnets for SPARC

【概要】

Commonwealth Fusion Systems (CFS) is building the world’s first compact net energy fusion device, SPARC, by utilizing recent advances in the commercial production of 2G REBCO coated conductors. SPARC’s delivery and operation will inform the design of ARC, the world’s first fusion power plant, scheduled to come online in the early 2030s. The SPARC magnet systems use two magnet technologies: Partitionally Insulated and Transposed (PIT VIPER) cables for the Central Solenoid (CS) and Poloidal Field (PF) magnets, and No-Insulation No-Twist (NINT) coils for the Toroidal Field magnets. The two magnet technologies were proven using model coil programs, TFMC and CSMC. CFS has constructed a manufacturing facility to build the SPARC magnets including facilities to test them at the sub-component scale in LN2 along with 2 large, cryogenic test stands for full testing of all PF, CS, and TF coils at low temperature and high field before delivering them to SPARC. This talk will provide an overview of the magnet build and tests to date.
