Animation to visualize the electron beam damage induced in calcium silicate hydrate phases

Kleiner, Florian

This dataset visualizes the electron beam damage induced by a scanning electron microscope (SEM) in calcium silicate hydrates (C-S-H). The specimen used is 28 days hydrated alite (water/solid = 0.5). It was scanned using a thermofischer scientific Helios G4 UX microscope at 350 V/25 pA wit a stage bias of 200 V.

This animation was an afterthought. Therefore, the dataset provides multiple magnifications and resolutions and some of the images are not in focus. Nevertheless, It can be seen, that the C-S-H needle in the right half of the image significantly deformes within a timespan of 124 seconds of constant scanning of that region.

File content:

  • All images ending with "raw" are the raw images provided by the SEM software including all metadata.
  • The file "C3S_CSH_e-beam-damage_aligned stack.tif" contains the aligned image set using the SIFT algorithm. It contains the correct scaling if opened with ImageJ.
  • The file "C3S_CSH_e-beam-damage_animation.gif" provides the final animation including a overlayed scalebar.

The research was supported by the Deutsche Forschungsgemeinschaft (DFG), grant number 344069666.
