-405°F cryogenic superconducting fusion magnet passes 40 kA electric current test
SMRTR summary
Helical Fusion has successfully tested a superconducting magnet design built for stellarator fusion reactors, which use complex 3D magnetic coils to contain plasma. Their UROCOIC conductor ran at 40 kiloamperes without failing, while withstanding massive electromagnetic forces at near-absolute-zero temperatures. The results, confirmed in a peer-reviewed study, bring the company closer to building Helix HARUKA and eventually a commercial fusion power plant in the 2030s.
