Brit Fusion Magnets Set For US Gamma Ray Bombardment Test

UK fusion company Tokamak Energy claims to have made a breakthrough in fusion magnets, developing technology capable of withstanding the electromagnetic bombardment from a fusion reaction while holding the reaction in place. It plans to put its technology to the test at a U.S. gamma ray facility in the desert.

At its Oxford headquarters, Tokamak Energy, which is collaborating with the UK government’s nuclear fusion program, has built a specialist gamma radiation cryostat system, designed around a vacuum device which insulates the magnets from fusion energy. The system is now set to be disassembled, shipped, and rebuilt at the Gamma Irradiation Facility based at the US Department of Energy’s Sandia Laboratories in Albuquerque, New Mexico.

Tokamak Energy said Sandia was one of the few places in the world capable of housing the system while exposing the company’s superconducting magnets to gamma radiation comparable with the expected emissions of a fusion power plant. Research and analysis on sets of individual magnets will run for six months at the New Mexico facility, which is so powerful it can do a 60-year lifetime test in just two weeks, Tokamak Energy said. The company recently signed an agreement with UK Atomic Energy Authority (UKAEA) to jointly develop technology, and share resources and equipment for the development of a Spherical Tokamak for Energy Production (STEP).
