PHOTOPiC先后被运用于计算纯N2、He/Ne/Xe/F2等混合气的光电离函数，为各类中高气压等离子体装置数字样机提供了关键基础数据。
| PHOTOPiC（PHOTOionization Parameter Calculater）是朱益飞博士开发的光电离函数求解器。该软件依据光谱强度、光电离效率和吸收系数，为包含流注传播过程的等离子体数值模型提供光电离函数，目前支持计算任意配比氮气、氧气、二氧化碳和水蒸气中的光电离参数。软件算法源于文献[1]，介绍与验证源于文献[2]，由工坊完成开发。 PHOTOPiC先后被运用于计算纯N2、He/Ne/Xe/F2等混合气的光电离函数，为各类中高气压等离子体装置数字样机提供了关键基础数据。
PHOTOPiC is a software for theoretically calculating the photoionization functions as well as fitting parameters for plasma modeling. 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, O2, CO2 and H2O molecules are included and can be modified by the users. The algrothm is based on [1] and the introduction and validation is presented in [2].
