Observations and Simulations of Tin Plasmas Formed by CO2 Laser Pulses

This is the experimental and simulation data associated with an article submitted to Physics of Plasmas. It contains two folders and one data file. Folder #1: dual probe csv files This folder contains the data from a complete experimental run with two probes in the chamber. Each csv file has 4 columns of data from Row 22. Column 1 contains the time data. Column 2 contains the laser pulse data Column 3 contains the planar probe data Column 4 contains the wire probe data Please note that the planar probe is positioned only at 100 mm, 80 mm, 60 mm, 40 mm and 20 mm from the target, while the wire probe is positioned at a greater range of distances from the target. Please see the data naming convention below which explains how to determine the distance of each probe from the target for each data file. Folder #2: planar probe csv files This folder contains the data from a complete experimental run with the planar probe inside the chamber. Each csv file has 3 columns of data from Row 22. Column 1 contains the time data. Column 2 contains the laser pulse data Column 3 contains the planar probe data Please note that the planar probe is positioned a range of distances from the target. Please see the data naming convention below which explains how to determine the distance of the probe from the target for each data file. File: complete_541ns.plt This is a text file which contains the simulation data for a range of parameters which were outputted from the 541 ns simulation at different edit times. All units are cgs. Data Naming Convention As each data sample was taken, it was important to name the saved correlated files in line with a strict convention, which would later enable the analysis of concomitant data sets and the proper association of probe-response with laser voltage and probe distances. Periods were avoided within the naming convention to avoid subsequent potential software conflicts. The naming convention selected contained reference to the following (see Figure 1). The base position of the probe: from 100 mm to 20 mm in steps of 20 mm. (In the dual probe csv files, the planar probe is held at this base position) The bias on the probe: ±15 V. The laser driving voltage: 22.5 kV, 25.0 kV, 27.5 kV. The actuator offset. In Figure 1, posn120 indicates that the probe has been moved 12 mm towards the target, closer than its starting position 020 mm i.e. it is 8 mm from the target. (The wire probe moves with this offset in the dual probe csv files. The planar probe moves with this offset in the planar probe csv files.) The sequence number of the shot within the group. e.g. : 020mm_pos15_27-5kV_posn120_003.csv Questions for clarification may be directed to Frank McQuillan at [phone], or [e-mail].本数据集为投稿至《Physics of Plasmas（等离子体物理）》的一篇学术文章配套的实验与模拟数据，整体包含2个文件夹与1个独立数据文件。 文件夹#1：双探针csv文件 该文件夹收录了腔体内搭载两支探针完成的完整实验采集运行数据。每个csv文件自第22行起包含4列数据：第1列为时间数据，第2列为激光脉冲数据，第3列为平面探针（planar probe）数据，第4列为钨丝探针（wire probe）数据。需注意，平面探针仅固定设置在距靶体100 mm、80 mm、60 mm、40 mm与20 mm的位置，而钨丝探针的可设置距离范围更广。请参阅下文的数据命名约定，以明确每个数据文件中两支探针距靶体的具体距离。 文件夹#2：单平面探针csv文件 该文件夹收录了腔体内仅搭载平面探针完成的完整实验采集运行数据。每个csv文件自第22行起包含3列数据：第1列为时间数据，第2列为激光脉冲数据，第3列为平面探针数据。需注意，平面探针的设置距离覆盖多个距靶体的位置，请参阅下文的数据命名约定以确定每个数据文件中探针的具体安装距离。 独立数据文件：complete_541ns.plt 该文件为文本格式，包含多组参数的模拟数据，均为541 ns模拟在不同模拟输出时刻输出的结果，所有单位均采用厘米-克-秒（cgs）制。 数据命名约定 在采集每个数据样本时，需严格遵循既定命名约定对保存的关联数据文件进行命名，这将便于后续对配套数据集的分析，以及实现探针响应数据与激光电压、探针安装距离的精准关联。为避免后续软件冲突，命名约定中未使用句号字符。 选定的命名约定包含以下要素（详见图1）： 1. 探针基准位置：以20 mm为步长，从100 mm至20 mm依次取值（在双探针csv文件文件夹中，平面探针固定采用该基准位置） 2. 探针偏置电压：±15 V 3. 激光驱动电压：22.5 kV、25.0 kV、27.5 kV 4. 执行器偏移量：例如标识`posn120`表示探针已向靶体方向移动12 mm，相较于初始基准位置020 mm，此时探针距靶体仅8 mm。（在双探针csv文件文件夹中，钨丝探针会携带该偏移量；在单平面探针csv文件文件夹中，平面探针会携带该偏移量） 5. 组内发射序列编号：例如文件名`020mm_pos15_27-5kV_posn120_003.csv`。 如有疑问可联系Frank McQuillan，邮箱：[e-mail]，电话：[phone]。
