The updated code will be verified through comparison to the previous IDL version using data from the C-Mod tokamak at MIT. Using the newly developed KN1DPy, we will perform predictive analysis of neutral densities for the SPARC fusion device. Currently, the SPARC team uses code to produce models for ICRH heating, turbulent transport, pedestal structure, edge profiles, magnetohydrodynamics (MHD) stability, and ripple loss of fast alphas [6][7]. However, there is a lack of adequate modeling of neutral profiles. With the development of KN1D, we hope to produce models for neutral densities to inform us further about electron densities and pressure gradients.
