PHOTOPiC: Calculate photo-ionization functions and model coefficients for gas discharge simulations
A program to compute photo-ionization functions and fitting parameters for an efficient photo-ionization model is presented. The code integrates the product of spectrum emission intensity, the photo-ionization yield and the absorption coefficient to calculate the photo-ionization function of each gas and the total photo-ionization function of the mixture. The coefficients of Helmholtz photo-ionization model is obtained by fitting the total photo-ionization function. A database consisting $\rm N_2$, $\rm O_2$, $\rm CO_2$ and $\rm H_2O$ molecules are included and can be modified by the users. The program provides more accurate photo-ionization functions and source terms for plasma fluid models.
