Abstract
The effect of high-fluence 30 keV helium ion irradiation with the fluence from 1018 to 3 × 1018 cm–2 in the temperature range from room temperature to 600°C on the morphology and surface structure of highly oriented pyrolytic graphite UPV-1T and fine-grained polycrystalline graphite MPG-8 has been studied experimentally. Ion-induced morphological elements complementing those previously established at low irradiation fluences (~1017 cm–2) have been identified. Irradiation of highly oriented pyrolytic graphite at high fluences results in delaminations, which manifest themselves as graphite flakes that are bent, twisted, and have whisker-like structures. Irradiation of fine-grained graphite does not significantly change its microstructure compared to highly oriented pyrolytic graphite.
期刊介绍：
Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
