Crossfield Fusion has been developing a novel compact fusion reactor targeting carbon free heat and power generation. The company adopted a new approach to building fusion reactors based on patented technology (US8138692) called the Epicyclotron. The company was founded in 2019 and developed a working fusion device in 2021 based on this approach. In October 2021 the company determined through the experimentation work completed and detailed ‘particle in cell’ modelling of loss mechanisms that the reactor would not scale as initially anticipated (and therefore could not be developed to deliver a net gain fusion reactor).
The company is currently exploring the use of this technology the developed in hydrogen isotope separation as part of the fusion fuel cycle.
