Japan's Helical Fusion Publishes Research Results on High-Temperature Superconducting Magnets

Helical Fusion recently announced that its joint research on high-temperature superconducting magnets with the National Institute for Fusion Science (NIFS) has passed peer review and been published in the Journal of Physics: Conference Series. The results, previously disclosed in a preliminary report, primarily validate the performance of high-temperature superconducting conductors for fusion reactor applications under strong magnetic fields and high currents. This study tested the UROCOIC high-temperature superconducting conductor independently developed by Helical Fusion. The research team fabricated the conductor into a double-pancake coil sample and used existing test equipment to simulate, as closely as possible, the magnetic field and current environment expected in future fusion reactors.

Rock Fusion Completes Key Processes for Stellarator 3D Non-Planar Superconducting Prototype Coil

Recently, the stellarator high-strength stainless steel armored 3D non-planar superconducting prototype coil developed by Rock Fusion (Shanghai) Technology Co., Ltd. has completed two key processes: 3D precision winding and ground insulation wrapping. The overall 3D geometric error of the coil is consistently controlled at the millimeter level, indicating that the company has preliminarily established key manufacturing processes including material adaptation, 3D precision forming, and insulation wrapping for high-field steady-state stellarator superconducting magnets. The stellarator is an important device for steady-state controlled nuclear fusion research, and 3D superconducting coils are used to generate the complex magnetic fields required to confine plasma. Unlike conventional planar coils, stellarator coils typically feature non-planar spatial structures with continuously varying curvature...

SuperMag New Energy Achieves Milestone Progress in Development of 25 T-Class High-Temperature Superconducting Toroidal Field Model Magnet

Recently, SuperMag New Energy has achieved two milestone progresses in the development of its 25 T-class high-temperature superconducting toroidal field model magnet: following the completion of R&D and testing of the first panel-type high-temperature superconducting single pancake coil, the company has initiated batch manufacturing of panel-type single pancake coils; meanwhile, the self-developed 24 cm² low-resistance detachable joint has completed prototype fabrication and performance testing in the liquid nitrogen temperature range, with an equivalent joint resistance of approximately 33 nΩ. These two progresses correspond to two critical aspects: stable manufacturing of single pancake coils and low-loss interconnection of multiple units. The project has advanced from the single-component process validation stage toward multi-pancake manufacturing and model magnet system integration. The single pancake coil is not an ordinary component in the model magnet, but rather a fundamental unit integrating conductor, panel structure, insulation, electrical connection, and testing interfaces. Each single pancake requires independent manufacturing and inspection, and also serves as the foundation for subsequent multi-pancake stacking, magnet excitation, and cryogenic operation.

U.S. Brookhaven National Laboratory Achieves Milestones in High-Luminosity Large Hadron Collider Upgrade

On July 29, the Large Hadron Collider (LHC) at CERN concluded its recent run and entered a four-year shutdown for maintenance. During this shutdown, some LHC components will be dismantled and rebuilt for the High-Luminosity LHC (HiLumi LHC) upgrade project. The U.S. Department of Energy's Brookhaven National Laboratory has recently achieved important production milestones in both accelerator and detector-related work. The LHC helps scientists study the fundamental structure of matter by accelerating and colliding two beams of protons traveling in opposite directions in a nearly 17-mile circular ring. The core goal of the HiLumi LHC upgrade is to significantly increase the number of particle collisions per unit time, i.e., enhance "luminosity," thereby increasing the chance of recording rare interactions.
