AbstractThe work presented in this thesis describes how an in-situ ion beam with Transmission Electron Microscope (TEM) system was upgraded to allow for the undertaking of experiments that will further the understandings of material science. In order to achieve more accurate experimental results, the MIAMI-1 (Microscopes and Ion Accelerators for Materials Investigations) in situ TEM ion beam line at Huddersfield University was upgraded.The beamline now has direct line of sight with the TEM reducing maintenance and improving alignment. The ion beam line can produce ions of various species. The energies of the ions run from 2-100 keV. This produces fluxes in the range of 1010-1014 ions/cm2/s. A
new system for measuring dosimetry has been introduced ensuring that experimental results are accurate and can be compared with the wider literature.
Accompanying this was the development of pre-experimental calculation techniques to allow for more accurate experimental parameter setup for use in spherical and cylindrical nanoparticle experiments. These calculations have already been used in the publications of papers and it is hoped that they will continue to be useful for future experiments.
The characteristics of ZrC once it had undergone helium ion implantation was also reported on. The formation and density of bubbles in the material were explored. Amorphisation analysis was performed with it being discovered that ZrC amorphises at 600°C under helium ion irradiation at 1 DPA a new discovery for the scientific community.
