Using the ST40 spherical tokamak and Demo4 HTS magnet test facility, the company develops plasma research, equipment integration, and superconducting technology. It supplies technology through TE Magnetics while pursuing research toward fusion electricity.

A specialist manufacturer of gyrotrons, high-power microwave sources for fusion plasma heating. Working with QST, it supported supply of eight ITER units and manufactures tubes for the additional 20 announced in 2026, meeting the 1.2 MW requirement.

A large-equipment supplier that manufactured five ITER TF coils and inner structures for all 19 coils. Through orders for 18 divertor outer vertical targets and full-scale prototyping, it extends its capabilities from superconducting-magnet structures to high-heat-flux in-vessel components.

Mitsubishi Electric

An electrical manufacturer producing ITER TF-coil winding packs and large superconducting coils for JT-60SA. In 2025 it completed two 8-m-diameter copper FPPC coils with QST, extending its manufacturing record from magnetic-field generation to in-vessel plasma-position control.

A materials supplier providing low-temperature superconducting wire for JT-60SA and ITER and REBCO high-temperature superconducting wire from its US subsidiary SuperPower. Building on supply and development cooperation with Tokamak Energy, it is extending involvement to FAST and assessments of UK HTS-wire capabilities.

高温超電導磁石を使う高磁場トカマクを開発。SPARCで科学的なエネルギー利得の実証を目指し、将来のARC発電所につなぐ。2026年は磁石製造・装置組立と発電所設計、供給網整備を並行して進める。

Developing controls for repeated laser irradiation of moving targets. Examine 10 Hz surrogate-fuel irradiation, laser-processing services, and the challenges remaining before electricity generation.

This approach uses a plasma structure called a field-reversed configuration. Helion's magnetic compression and TAE's beam-driven approach differ in operation and fuel strategy.
