Data for Article: Cryo-HIM-SIMS on the npSCOPE

This data sets contains the raw data files of data published in the article "Cryo-HIM-SIMS on the npSCOPE: Correlative topographic, transmitted and SIMS imaging at cryogenic temperatures". The manuscript can be found at: https://doi.org/10.1021/acs.analchem.5c06908 .csv files are text files containing meta data for SIMS spectra acquisiton. .raw files are text files containing the raw count information from the SIMS detector from which isotopic maps were generated. Each row represents one pixel with columns one and two being the x and y position, and the rest of the columns represent the channel positions of each ion measured at the detector at that pixel on the sample. Channels can be mapped to masses using the .csv metadata. .tif of SE and STIM images are provided in cases where images series were obtained over time (e.g. Au foil cooling experiment, Silica coated Au beam damage analysis) or when images were further processed for better contrast (Keratinosense STIM) .tyield files contain simulated ion transmission yields in Au for varying crystal directions as mapped onto a Cartesian grid in a stereographic projection. Simulations were performed using the IMplant and Sputter sImuLator (IMSIL) for a crystal at both room and cryogenic temperatures. The first column and row of the data are the axes. The exact experimental details can be found in the publication.本数据集包含发表于论文《Cryo-HIM-SIMS on the npSCOPE：低温环境下的形貌、透射与SIMS关联成像》中的原始数据文件。该论文可通过以下链接获取：https://doi.org/10.1021/acs.analchem.5c06908 .csv格式文件为文本文件，存储二次离子质谱（Secondary Ion Mass Spectrometry, SIMS）谱采集所需的元数据。 .raw格式文件为文本文件，存储来自SIMS探测器的原始计数信息，用于生成同位素分布图。每一行对应一个像素点，其中前两列分别为该像素的x、y坐标，其余列对应该样品像素点在探测器上测得的各离子的通道位置。可通过.csv格式的元数据文件将通道与离子质量进行关联。 针对随时间序列采集的图像（如金箔冷却实验、二氧化硅包覆金束流损伤分析场景）或为提升对比度而进行后期处理的图像（如角蛋白感知STIM图像），我们提供了对应二次电子（Secondary Electron, SE）与扫描透射离子显微术（Scanning Transmission Ion Microscopy, STIM）图像的.tif格式文件。 .tyield格式文件包含不同晶体取向下金离子的模拟透射产率数据，该数据以立体投影中的笛卡尔网格形式进行映射。模拟计算通过IMplant与溅射模拟软件Sputter sImuLator（IMSIL）完成，分别针对室温和低温环境下的晶体样品。该数据的首行与首列为坐标轴刻度。 具体实验细节可查阅上述发表论文。
