Plasma-Material Interface (PMI) mixes materials of the two worlds, creating in between a new entity, a P-M dynamical surface which communicates between the two, creating one of the most challenging areas of multidisciplinary science, which has many fundamental processes and synergies.
How to build an effective science and integrated theoretical-experimental approach for PMI? The traditional trial-and-error approach to PMI for future fusion devices by successively refitting the walls of toroidal plasma devices with different materials and component designs is becoming prohibitively slow and costly. Since erosion, sputtering, retention, redeposition, reflection, displacement, etc. originate from atomic processes we seek to construct the PMI science from the bottom up, recognizing its multi-scale character and building from the shortest, atomic, to the longest time and spatial scales.
