The work reported in this paper has already been presented internally by placement student Jacob Young at a MAST Physics and Technology meeting on December 17 2020. Therefore it does not require a paper review presentation. Please also note that the paper is proposed for inclusion in a special issue of Plasma Research Express linked to the recent I…

Fundamental flaws in the Heisenberg Hamiltonian are highlighted in the context of its application to BCC Fe, including the particular issues arising when modelling lattice defects. Exchange integrals are evaluated using the magnetic force theorem. The bilinear exchange coupling constants are calculated for all the interacting pairs of atomic ma…

The paper presents the results of an experimental study of deuterium retention in W and W-Ta alloy that were exposed to first-wall relevant low flux (~1020 m-2s-1) deuterium plasma in the ECR plasma generator PlaQ. Subsequent analysis included surface imaging by optical microscopy, deuterium depth profiling by nuclear reaction analysis (NRA) and me…
