Abstract

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 N2\rm N_2, O2\rm O_2, CO2\rm CO_2 and H2O\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.
