These two datasets comprise the Rutherford backscattering spectrometry results from the last global migration experiment in TEXTOR by MoF6 injection. The materials assessed with this technique were molybdenum, tungsten and ferritic metals (heaviest component: Ni or Cu - denoted "Ni" in the dataset). The data gives information about these materials deposited on the tokamak limiters, in 1E15/cm2 or ppm, at positions denoted in degrees (torus coordinate system). Details are given in the .txt file "column_names", as well as in the header comments of the Excel sheets.

Figures of the paper and SEM images for the figure 3. The filenames of SEM images for fig.3 were constructed with consecutive number and location name. The locations of each images taken were determined by SEM images with low magnification with filename "locations.png". plot.dat is a file contains the raw values of average size and hole density of each images. "macro_a.ijm" is a macro file for imageJ software.

The manuscript “On the effects of different regimes of plasma pulses affecting the material due to their succession” is based on the analysis of this data. The study focused on how the combined effects of different irradiation regimes influence the damage development in pure tungsten. It was carried out using measurements of electrical conductivity, scanning electron microscopy analysis for obtaining images for the analysis of surface and bulk damages, and micro-hardness measurements. Keywords: electrical conductivity; tungsten; plasma facing materials; PFC, non-destructive testing; the order of succession of plasma pulses

Raw data for plots in manuscript

The data is arranged into 2 folders: 1. SEM folder, which contains the raw SEM images of the surface morphology of the investigated material and the results of transmission Kikuchi diffraction (TKD). 2. TEM folder, which contains the raw TEM images acquired on the cross-section of the investigated material in as-deposited and He-irradiated conditions. One may also find the selected area diffraction (SAED) patterns and the EDS elemental maps.

Two new quartz crystal microbalance (QMB) systems have been installed at different locations in the mid-plane of EAST to measure erosion and deposition of the first wall materials. The two QMBs with different distances from the plasma show complex and distinct erosion and deposition behavior. The QMB in the mid-plane H port closer to the plasma shows a relatively higher net erosion result with an average erosion rate of 1.34 ng/(cm2 s). The normal discharges mainly contribute to the total net erosion and the maximum erosion amount reaches up to 110 ng/cm2 . Contrarily, a slight net deposition of 0.11 ng/(cm2 s) is obtained for the QMB in the mid-plane G port further away from the plasma and the erosion and deposition amount of most discharges are much lower due to lower particle flux. The disruptive discharges lead to a total net deposition rate of 0.48 ng/(cm2 s). Measurement results by the QMBs are demonstrated by a good agreement with the post-mortem analysis by Rutherford Backscattering Spectrometry (RBS).
