Design of a Prototype 20 Tesla, Single Turn, Toroidal Field Coil for the Fusion Ignition Experiment (IGNITEX)
The electromagnetic design of the fusion ignition experiment (IGNITEX)[l] combines unconventional pulsed power and magnet technologies. The experiment should produce an ignited plasma in a relatively simple and low cost way.[2,3) The proposed IGNITEX toroidal field (TF) coil is a 20 T, single tum, toroidal magnet powered by homopolar generators (HPGs). In order to demonstrate the magnet technologies, the Center for Electromechanics at The University of Texas at Austin (CEM-UT) is building a 0.06 scale prototype toroidal field coil to be powered by an existing 60 MJ, 9-MA, HPG power supply. This element of the Ignition Technology Demonstration (ITD) program is funded by the Texas Advanced Technology Program and the Texas Atomic Energy Research Foundation.
