“…To date, however, the majority of work on microstructural radiation damage in graphite has been confined to ex situ analysis of neutron (for examples see [31][32][33][34][35]) and ion (for examples see [36][37][38][39][40]) irradiated material with only a small number of studies using TEM with in situ ion [41][42][43][44][45] and electron [15,[46][47][48] irradiation. Radiation damage is a complex dynamic process in which multiple mechanisms compete to determine the ultimate outcome.…”

“…Studies of the carbon cluster emissions under energetic particle bombardments identify and relate to the nature of the irradiation damage. The nature and type of the irradiation-induced damage in graphite is well documented [2][3][4][5][6]. The emergence of the new allotropic forms of carbon i.e.…”

“…Investigations of the sputtered carbon species C x ;x≥1 that contain mono-, di-, tri-atomic and higher clusters from irradiated graphite have been conducted [2][3][4][5][6]. We have extended these studies to monitoring the sputtered C x from MWCNTs with the view to understand the nanotube fragmentation pattern and to see the effects of the accumulation of the sputtered species in the intra-nanotube space.…”

Experiments with multi-walled carbon nanotubes (MWCNTs) and graphite as targets in a source of negative ions with cesium sputtering (SNICS) have shown that MWCNTs with nm radii and μm length can be compared with μm-size graphite grains to understand the irradiation effects that include the formation, sputtering of carbon clusters and the resulting structural changes. The simultaneous adsorption of Cs˚ on the surface and bombardment by energetic Cs + is shown to play its role in the cluster formation and sputtering of carbon atoms and clusters (C x ; x ≥1) and the cesium-substituted carbon clusters (CsC x ) as anions. Sputtered species' qualitative and quantitative outputs are related to their respective structures. Structural changes are shown to occur in MWCNTs and seen in SEM micrographs. The individual identity of the heavily bombarded MWCNTs may have given way to the merged structures while effects on the structure of heavily irradiated graphite grains size needs to be further investigated.

“…Its mosaic structure is characterized by axis texture in the [0 0 1] direction normal to the plate surface; disorientation of the basal planes does not exceed 50 0 . The pronounced effect of temperature on ion-induced structural, emission, and morphological changes different from the respective ones for polycrystalline graphites is observed for HOPG upon high-fluence ion irradiation with Ar + and N 2 + ions with energies of tens of keV [3,4,[13][14][15][16][17][18]. In particular, it has been found that the sputtering yield is practically twofold lower upon sputtering of the basal plane of UPV-1T with 30-keV Ar + ions in comparison with Y values upon the sputtering of polycrystalline graphites in a wide range of ion incidence angles [17].…”
