Lockheed Martin Compact Fusion Project: Diagnostic Development and Comparison with Simulations

The T4B experiment is a linear, encapsulated ring cusp confinement device, designed to develop a physics and technology basis for a follow-on high beta machine as part of the compact fusion reactor program. We present a suite of non-invasive diagnostics for the T4B experiment looking at several aspects of the plasma performance including plasma emissions (bolometry, spectroscopy), stability, and magnetic field perturbations. We also show comparisons of synthetic diagnostics to measured data. The synthetic diagnostics can be run with a variety of equilibrium reconstructions and simulations, and the results are compared against measured data to validate the models and correlate the data from the different diagnostics. Future diagnostic plans are also presented.
