Benchmark Case Data for 3D FEM Particle-in-Cell Validation

The attached zip contains both data and analysis scripts for the first two particle-in-cell examples in the associated paper. In particular,(1) The BeamExpansion folder contains output z vs r phase space data from the quasi-Helmholtz FEMPIC code used in the paper at 3 ns (fempic.csv), as well as the equivalent data from an XOOPIC simulation (xoopic.txt). The analysis is done in the ipython notebook file in the folder. All of the plots in the paper was generated using this same script.(2) The PiModeAccelerator folder contains 6D phase space data from the quasi-Helmholtz FEMPIC code at three separate times in the simulation. The plots in the paper were generated using the associated ipython notebook. In addition, the notebook contains a simple single particle tracking code (along with documented methodology) that were used to generate the SPT results in the paper. The tracker makes use of exported fields from CST (pi_mode_one_port.txt), and the FEMPIC code/CST made use of the 3D object described in pimode_one_port_correct_waveguide.sab. 

所附压缩包包含对应论文中前两个粒子网格（particle-in-cell, PIC）示例所需的全部数据与分析脚本。具体如下：
(1) BeamExpansion 文件夹包含论文中采用的准亥姆霍兹FEMPIC代码在3纳秒（ns）时刻输出的z-r相空间数据（文件为fempic.csv），同时还包含XOOPIC仿真得到的等效相空间数据（文件为xoopic.txt）。相关分析均通过该文件夹内的IPython笔记本（IPython Notebook）完成，论文中的所有绘图均由该脚本生成。
(2) PiModeAccelerator 文件夹包含准亥姆霍兹FEMPIC代码在仿真过程中三个不同时刻输出的六维（6D）相空间数据。论文中的相关绘图均通过配套的IPython笔记本生成。此外，该笔记本还内置一套简易的单粒子追踪（single particle tracking, SPT）代码，附带完整的方法文档，论文中的单粒子追踪结果均由该代码生成。该追踪程序调用了从CST软件导出的场数据（文件为pi_mode_one_port.txt），而FEMPIC代码与CST软件均使用了pimode_one_port_correct_waveguide.sab中描述的三维对象。
