Monte Carlo-calculated depth distributions of K and L x-ray fluorescence generated by keV electrons incident upon thick targets made of Au, W, Rh, Mo, Cu, and Cr

Provided is the following:
(1) Monte Carlo-calculated (PENELOPE [v. 2014]) K and L x-ray fluorescence differential in electron penetration depth scaled by the continuous slowing down approximation (CSDA) range.
(2) Radiative transition data and photon mass attenuation coefficients extracted from the PENELOPE materials database.
(3) An example MATLAB code that implements the provided data in an analytical model for the prediction of characteristic x-ray emission from a thick tungsten target.

(1) 采用PENELOPE [2014版]程序通过蒙特卡洛（Monte Carlo）方法计算得到的、以连续慢化近似（continuous slowing down approximation, CSDA）射程为归一化依据的电子穿透深度微分K、L系X射线荧光数据；
(2) 从PENELOPE材料数据库中提取的辐射跃迁数据与光子质量衰减系数；
(3) 一段示例MATLAB代码，其将上述数据集应用于解析模型，用于预测厚钨靶的特征X射线发射特性。
