The updated code will be verified through comparison to the previous IDL version using data from the Alcator C-Mod tokamak at MIT. Additionally, we will use the newly developed KN1DPy to compare both Lyman-alpha data from C-Mod discharges as well as to compare to SOLPS-ITER modeling. This testing against experimental results and more complex modeling will allow us to verify the continued applicability of KN1D’s predictions, and thus assess the need to upgrade the atomic physics processes in KN1D to leverage open-source databases of atomic physics reactions such as ADAS.
