SPARC will be outfitted with three systems of X-ray crystal spectrometer arrays. Two of these are designed using cylindrically bent crystals to achieve high spectral-resolution for ion temperature and toroidal velocity measurements via imaging He-like Kr and Ne-like Xe. The last acts as a spectral survey system to monitor Ne-like W and nearby Hi and He-like emission from Cr, Fe, Co, Ni, Cu. Line radiation intensities are calculated using the FLEXIBLE ATOMIC CODE for atomic data and COLRADPY for collisional-radiative modeling then convoluted with a Voigt line shape. Free-free, free-bound, and two-photon continuum radiation is also included. The TOFU code is used to perform volume-of-sight integration to produce synthetic detector images. Also presented is cross-validation performed using the XICSRT Monte Carlo ray-tracing code. Ion temperature and toroidal velocity profiles are reconstructed using TOFU via tomographic inversion. <a href="http://library.psfc.mit.edu/catalog/reports/2020/24ja/24ja134/abstract.php">PSFC REPORT PSFC/JA-24-134</a><br /><br />This work is supported by Commonwealth Fusion Systems RPP031.<br /><br />If this record does not contain the full text, then the manuscript has been embargoed by the publisher thus restricting open access for 12 to 24 months after publication.
