A TriForce module for performing inline Hydrogen spectroscopy on the Princeton Reversed Field Configuration.

The Princeton Reversed Field Configuration-2 (PFRC-2) is a rotating magnetic field-heated (RMF-heated) field reversed configuration (FRC) with the primary goal of reaching average ion temperatures of  > 500 eV. Experimental measurement of electron temperatures via visible line emission has been performed on the PFRC-2, but the interpretation methods used result in variations of up to 50%. Integrated simulations including both the device and its diagnostics can inform the design of future experiments via time and resource-efficient exploration of the relevant parameter space. Proposed here is a supplemental module to the University of Rochester’s TriForce Library for Integrated Numerical Kinetics (TFLink), a particle-in-cell (PIC) code that has done preliminary integrated simulations of the PFRC-1 device. This module would allow for calculations of the Hydrogen radiation production in each computational cell to be performed inline, allowing for synthetic data collection, localized both spatially and temporally. These synthetic data are then compared to experimental data.
