The 3rd International Workshop on Models and Data for Plasma-Material Interaction (MoD-PMI 2016) was held in Loughborough, UK from 22 to 24 June 2016. It brought together researchers from the areas of fusion energy and materials science to review advances, both experimental and in the modeling of processes relevant to plasma-wall interaction in fusion devices. The workshop series provides a bridge between fundamental computations and interpretation of experimental data; it addresses a variety of processes spanning a wide range of scales including erosion, transport and trapping of hydrogen and helium in the wall, changes in the material microstructure, composition and morphology.
MoD-PMI 2016 Website
- Direct uses of first-principles quantum-mechanical codes (DFT and beyond) for the study of irradiated microstructure and trapping/transport of hydrogen and helium in materials components of fusion devices.
- Optimization of parameters in semi-empirical codes from electronic structure calculations in the form of interaction potentials and transition rates for classical models.
- Molecular Dynamics, Kinetic Monte-Carlo, Rate-equation studies of PMI, radiation damage processes and materials surface evolution.
- Integrated, accelerated approaches and Multi-scale simulations involving neutron-induced nuclear reactions, transmutation, and thermo-mechanical properties under prolonged operation times in reactor materials.
- Uncertainty quantifications of theoretical and experimental PMI data.
- Deposition of energetic plasma particles into the surface and physical/chemical sputtering of surface materials into the plasma.
- Changes in surface compositions, morphology and materials microstructure due to plasma bombardment and neutron irradiation.
- Experimental approaches including thermal desorption spectroscopy (TDS), positron annihilation spectroscopy (PAS), permeation experiments, transmission electron microscopy (TEM) and other microscopies like STM and AFM.
