DataRelease_JPARC_SC.zip show the values for the maximum intra-bunch frequency and the normalized recoherence period for each parameter at the simulation and measurement. intrabunch_frequency1.txt was used to obtain Figs. 33 and 39 (Fig. 26 in PRAB version), which are plots of the maximum intra-bunch frequency with fixed beam intensities for different chromaticities. The first element of the data indicates the negative chromaticity on the x-axis, and the second element of the data indicates the maximum intra-bunch frequency on the y-axis.intrabunch_frequency2.txt was used to obtain Figs. 28a and 35a (Fig. 18 in PRAB version), which are plots of the maximum intra-bunch frequency for the synchrotron period. The first element of the data indicates the synchrotron period on the x-axis, and the second element of the data indicates the maximum intra-bunch frequency on the y-axis.recoherence_period1.txt was used to obtain Figs. 31 and 37 (Fig. 23 in PRAB version), which are plots of the normalized recoherence period with fixed chromaticities for different beam intensities. The first element of the data indicates the beam intensity times 10E-12 on the x-axis, and the second element of the data indicates the normalized recoherence period on the y-axis.recoherence_period2.txt was used to obtain Figs. 28b and 35b (Fig. 19 in PRAB version), which are plots of the normalized recoherence period for the synchrotron period. The first element of the data indicates the synchrotron period on the x-axis, and the second element of the data indicates the normalized recoherence period on the y-axis. DataRelease_JPARC_SC2.zip contains the simulation and experimental data, along with analysis scripts, used to generate the figures presented in our study. All data files are provided in ROOT format and can be processed using the included ROOT scripts. The project is structured to allow reproducibility of all figures in the manuscript. The main.sh script sequentially executes all analysis scripts to reproduce the figures and key comparisons between simulation and measurement results. The scripts are categorized as follows: ・fig*.cxx: Reproduces the corresponding figure in the manuscript shown in Figures 1~10, 12, 14, 15, 18, 19, 20, 23, and 26.・sim_*.cxx: Process simulation results such as FFT spectra, beam positions, and dipole signals to reproduce figures corresponding to the conditions shown in Figures 11, 16, 21, and 24.・exp_*.cxx: Process experimental results for comparison with simulation results to reproduce figures corresponding to the conditions shown in Figures 13, 17, 22, and 25. Output plots are saved in the out/ directory. All ROOT scripts are written in C++. All scripts were developed and tested using ROOT 6.32.04. Contents・data/: ROOT files for simulation and experimental data.・script/: C++ analysis scripts for ROOT.・main.sh: Batch script to reproduce all figures.・out/: Output directory for plots (generated upon execution). How to use chmod +x main.sh./main.sh This will run all ROOT scripts and generate plots for the figures in the manuscript.本压缩存档包含来自论文《日本质子加速器研究复合体（Japan Proton Accelerator Research Complex）主环（Main Ring）大色品（chromaticity）下束团内运动（intra-bunch motion）的空间电荷效应（space charge effects）》的分析数据。该论文的arXiv标识符为arXiv:2501.16654 [acc-ph]，其提交至《Physical Review Accelerators and Beams (PRAB)》的版本的DOI为10.1103/yx9r-lhxq。 DataRelease_JPARC_SC.zip 包含了仿真与测量场景下各参数对应的最大束团内频率（maximum intra-bunch frequency）与归一化再相干周期（normalized recoherence period）的数值。 intrabunch_frequency1.txt 用于绘制图33和图39（PRAB版本中为图26），该类图表为固定束流强度下不同色品的最大束团内频率曲线，数据第一元素为横轴的负色品值，第二元素为纵轴的最大束团内频率。intrabunch_frequency2.txt 用于绘制图28a和图35a（PRAB版本中为图18），该类图表为同步辐射周期（synchrotron period）的最大束团内频率曲线，数据第一元素为横轴的同步辐射周期，第二元素为纵轴的最大束团内频率。recoherence_period1.txt 用于绘制图31和图37（PRAB版本中为图23），该类图表为固定色品下不同束流强度的归一化再相干周期曲线，数据第一元素为横轴的束流强度（数值为原始束流强度乘以10^-12），第二元素为纵轴的归一化再相干周期。recoherence_period2.txt 用于绘制图28b和图35b（PRAB版本中为图19），该类图表为同步辐射周期的归一化再相干周期曲线，数据第一元素为横轴的同步辐射周期，第二元素为纵轴的归一化再相干周期。 DataRelease_JPARC_SC2.zip 包含了本研究中用于生成论文插图的仿真与实验数据，以及配套分析脚本。所有数据文件均采用ROOT格式（ROOT format），可通过附带的ROOT脚本进行处理，本项目的结构可实现论文中所有插图的复现。 main.sh 脚本可按顺序执行所有分析脚本，以复现插图并完成仿真与测量结果的关键对比。脚本分类如下： ・fig*.cxx：复现论文中对应图1~10、12、14、15、18、19、20、23及26的插图。 ・sim_*.cxx：处理仿真结果（如快速傅里叶变换（Fast Fourier Transform, FFT）频谱、束流位置及偶极子信号），以复现对应图11、16、21及24的插图。 ・exp_*.cxx：处理实验结果以与仿真结果对比，复现对应图13、17、22及25的插图。 输出的绘图文件将保存至out/目录。所有ROOT脚本均采用C++编写，开发与测试环境为ROOT 6.32.04。 项目目录结构如下： ・data/：存放仿真与实验数据的ROOT文件。 ・script/：用于ROOT的C++分析脚本目录。 ・main.sh：用于复现所有插图的批处理脚本。 ・out/：绘图结果输出目录（执行脚本后自动生成）。 使用方法： chmod +x main.sh ./main.sh 该命令将运行所有ROOT脚本并生成论文插图对应的绘图文件。
