After the first plasma in 2006, the Experimental Advanced Superconducting Tokamak (EAST) is approaching now 20 years of operation. It has been the first tokamak featuring both toroidal and poloidal superconducting coils. In particular, its toroidal field (TF) magnet system is composed by 16 coils with an height of about 4 m.
The superconducting coils are operated at a temperature of 4.5 K,...
Startup and quench behavior in a FNSF scale Toroidal Field (TF) HTS magnet were explored in a previous ASC paper. In that study a mix of superconducting and resistive materials are
arrayed in a Bitter Plate like arrangement. In the studies presented here, various quench mitigation scenarios are explored. The conductor arrangement is a parallel set of HTS channels with radially...
Stellarators confine plasma in a stable toroidal configuration using twisted external magnetic fields. However, this requires complex 3D coil shapes that can pose a significant design, manufacturing, and maintenance challenge. To address this challenge, Thea Energy, Inc. is developing the planar coil stellarator. This approach utilizies multiple smaller, individually energized coils that...
