Description
Activities carried out in Russia during the period from May 2023 until September 2025 on atomic, molecular and plasma-material interaction (PMI) data will be presented, including the development and maintenance of databases, a brief review of original research papers regarding the generation of atomic and PMI data, as well as uses of such data in controlled nuclear fusion research. The most recent Russian conferences predominantly reflecting the progress on PMI data will also be overviewed.
Activities on databases include both those being performed in the framework of the Virtual Atomic and Molecular Data Centre (VAMDC) consortium and those being pursued in Russian institutions beyond that framework.
The original research works on the generation of atomic and PMI data include studies of charge exchange and ionization processes in collisions of W with H$^+$, D$^+$, T$^+$ ions, as well as rather extensive studies of sputtering of Tungsten and Beryllium by Hydrogen isotopes and light impurities.
The usage of atomic data in the recent controlled fusion research works in Russia includes studies of plasma parameters on operating tokamak and stellarator devices, namely, Globus-M2 spherical tokamak and L-2M stellarator, as well as studies related to the prospective Tokamak with Reactor technologies, i.e. the TRT project.
The major Russian conferences in 2024-2025 on the interactions of plasmas with materials are the 27th and the 28th International Conferences on Plasma Surface Interaction organized by Moscow Engineering Physics Institute (MEPhI) and the 27th International Conference on Ion-Surface Interactions organized primarily by the Ministry of Science and Higher Education of the Russian Federation.
The overview covers activities pursued at Rosatom’s institutions, NRC Kurchatov Institute, at universities such as Peter the Great St.Petersburg Polytechnic University, Novosibirsk State University, Moscow Engineering Physics Institute, and at the institutions of the Russian Academy of Sciences, namely, Ioffe Institute, P.N. Lebedev Physical Institute, G.I. Budker Institute of Nuclear Physics and other organizations. The major frameworks are the Russian Federal project on fusion energy technologies and the participation of Russia in the ITER project.
