Magnet Technology Demonstration for an Ignition Single-Turn Tokamak

The Center for Electromechanics at The University of Texas at Austin (CEM-UT) has designed, built, and is now testing a full torus, single-turn magnet designed to produce 20 Tesla (T) on-axis. The Ignition Technology Demonstration (ITD) as it is called is a 0.06 scale Texas Ignition Experiment (IGNITEX) toroidal field (TF) magnet prototype. The purpose of the ITD program is to demonstrate the operation of a 20 T, single-turn TF coil powered by homopolar generators (HPGs). To date the prototype TF magnet has produced a purely toroidal, on-axis field of 15.0 T without an axial preload.
