Accelerators for Material Science - 1
- Khalid Hattar (University of Tennessee Knoxville)
Integrated science and technology efforts in the field of controlled thermonuclear fusion are directed towards the construction and operation of a rector-class machine for electricity production. In the interdisciplinary world of fusion research, the role of particle accelerators is at least five-fold: (i) provision of nuclear data for ion-material interactions; (ii) ion beam analysis (IBA)...
Energetic particle irradiation creates a multitude of metastable defects through atomic displacements in lattice structure and/or excitations/ionizations in electronic configurations of a material. These defects are then responsible for the microstructural evolution and property changes of the material, which often come down to a balance of kinetic processes that determine whether the material...
In situ accelerator materials science is poised to unlock far more information regarding how nuclear materials behave under irradiation, if utilized properly. Many of the questions which need answering for both fission and fusion power cannot be readily answered with increasingly rare neutron sources, nor do they need them at this stage. Before any neutron irradiation should take place,...
Ion accelerators are commonly used to simulate the effects of radiation damage in nuclear materials and when coupled to a Transmission Electron Microscope (TEM) one can follow the dynamics of radiation damage, precipitation, formation of gas bubbles, etc at a microscopic scale in almost real-time. Therefore, in principle, one can develop a detailed picture of radiation damage buildup in a...
