The high-temperature superconducting current lead (HTSCL) plays a key role in supplying large currents to the ITER superconducting magnets. To measure the temperature of the HTSCL cooled by helium gas, PT-100 sensors are installed at both the warm end of the HTS section and the room-temperature terminal. These sensors are exposed to a high-voltage environment, depending on the type of ITER...
Commonwealth Fusion Systems (CFS) is developing and building a commercially relevant fusion energy machine that will produce more energy than is put into it. In this research, a reusable structural case for testing toroidal field (TF) magnets in the Coil Test Stand Cryostat prior to integration in the SPARC Tokamak has been developed and is currently employed in this critical evaluation of TF...
The magnets of the SPARC tokamak as developed by Commonwealth Fusion Systems and the Massachusetts Institute of Technology include superconducting magnet termination cables that supply power to the winding pack. It is important to qualify these superconducting cables because they are epoxied into the cable magnets, making their removal extremely difficult, possibly scrapping a magnet. We...
Thea Energy, Inc has designed, developed, and tested the “Canis” 3x3 array of high-temperature superconductor (HTS) planar coils, which will serve as a prototype for the development of the “Eos” planar coil stellarator. The Canis 3x3 magnet array support systems consist of a vacuum vessel, a radiation shield, first and second stage cooling systems, a magnet current distribution system, and a...
Magnets remain the cornerstone technology in the development of high field fusion machines such as tokamaks. In this context, high-temperature superconductors (HTS) and the conductors derived from them are considered enabling technologies . HTS materials enable higher magnetic fields, paving the way for more compact and potentially higher-performance machines. However, the integration of these...
The superconducting (SC) magnets of the Divertor Tokamak Test (DTT) facility, a fusion experiment under construction at the ENEA Research Center in Frascati, Italy, require several tens of kA, necessitating the use of SC feeders. These feeders are based on the Cable-in-Conduit Conductor (CICC) concept, where a bundle of twisted NbTi strands is encased in a stainless-steel jacket and cooled by...
Fermi National Accelerator Laboratory (Fermilab) is currently constructing a new High Field Vertical Magnet Test Facility (HFVMTF) designed for testing High Temperature Superconducting (HTS) cables in high magnetic background field. This facility is expected to offer capabilities similar to those of EDIPO at PSI and FRESCA2 at CERN. The background magnetic field of 15 T will be generated by a...
