title: Raman imaging data

description: The data set used for the articles consists of a series of Raman imaging measurements conducted on the surfaces (XY axis) and depth profiles (XZ axis) of three types of nuclear graphite (IG-110, NBG-17, and in-house NCBJ graphite). The measurements were performed using a confocal WITec alpha 300R microspectrometer (Oxford Instruments), controlled by WITec Control 5.2 software and equipped with a 532 nm laser. The maps had the following dimensions: for the surface, 25 × 25 μm in the X and Y directions (50 points per 50 lines, with a point taken every 0.5 μm), and for the in-depth analysis, 25 × 25 μm in the X and Z directions (50 points per 50 lines, with a point taken every 0.5 μm). The measurements were acquired using a Zeiss LD EC Epiplan-Neofluar Dic 50x/0.55 lens, a 600 lines/mm grating, and a 3-second acquisition time. The laser power was set to 10 mW for surface measurements and 20 mW for in-depth analysis. Subsequent analysis of the acquired data was conducted using WITec Project FIVE 5.2 software, which involved cutting the spectral region of interest, baseline correction, cosmic ray removal (CCR), band fitting, basic calculations, and chemometric analysis (K-means clustering, KMC). The data presented in this study are as-measured with no postprocessing applied.
