PF and TF power systems for the Fusion Ignition Research Experiment (FIRE)

The primary goal of the FIRE preconceptual design is to affordably conduct physics experiments in the fusion ignition regime with self-heated plasmas. The device could also permit advanced tokamak experiments in deuterium lasting several minutes. Tradeoff studies considering MVA and flattop duration have identified TF and PF magnet power system designs expected to have low cost, consistent both with the mission to enter the ignition regime and the possibility to conduct long pulse deuterium experiments. In addition, a performance-extending upgrade path for the power system has been identified which could be followed later, if experimental results justify further increasing the maximum toroidal field and plasma current or lengthening the duration.
