TE Magnetics HTS magnet systems

Tokamak Energy


Overview
The company's high-temperature superconducting magnet business, built on REBCO tape wound in-house, sold both into fusion programmes and into non-fusion markets including power distribution, propulsion, motors and generators, and analytical science. Demo4, its 44-coil demonstration system, is the technology proof point.
Demo4 reached 11.8 tesla with seven million ampere turns in November 2025, the first HTS magnet system to reproduce fusion-relevant magnetic fields at system level. The division won the £70M STEP Magnet Systems Partner contract in April 2026, acquired Ridgway Machines in 2025 to expand manufacturing, and is working with Furukawa Electric to build UK HTS tape capability.
