The 24th International Conference - Plasma Surface Interaction held at MEPhI

On February 4-5, MEPhI hosted the 24th International Conference "Plasma-Surface Interaction" organized by the Institute for Laser and Plasma Technologies.

The conference was held online brought together more than 100 participants – representatives of leading research centers and universities of Russia (National Research Centre - Kurchatov Institute, TRINITY, Krasnaya Zvezda JSC, Lebedev Physical Institute, Budker Institute of Nuclear Physics, Ioffe Physical-Technical Institute of the RAS, Project Center ITER, etc.) and foreign countries.

This year the conference was dedicated to the memory of Valery Aleksandrovich Kurnaev, who passed away on November 23, 2020.

Valery Aleksandrovich was a well-known and respected scientist in the field of plasma physics and controlled thermonuclear fusion. For 30 years he was head of the Department of Plasma Physics of MEPhI and was the standing chairman of this conference.

The memorial part was opened by the rector of MEPhI Mikhail Strikhanov and the director of the LaPlaz Institute Andrey Kuznetsov. The director of scientific and technical research and development of ROSATOM Viktor Ilgisonis, scientific director of JSC TRINITY Vladimir Cherkovets and many other famous scientists, friends, colleagues and relatives spoke about their memories of Valery Alexandrovich.

The scientific part of the conference was focused on the physical problems of plasma-surface interaction in controlled thermonuclear fusion installations. The latest experimental and theoretical results on processes on the surface of a wide range of materials under irradiation with ion beams and high-power plasma flows typical of thermonuclear installations were discussed. The report of Alexander Vasiliev from Budker Institute of Nuclear Physics (Novosibirsk) was a review of studies on dynamics behavior of tungsten by high-power pulsed loads using the original complex IN-SITU diagnostics. In a report prepared by Stepan Krat from MEPhI, methods of low-temperature removal of hydrogen isotopes from lithium were demonstrated. A large number of reports were devoted to the formation of a nanostructured relief on the surface of tungsten irradiated with helium plasma. The engineering aspects of designing in-chamber elements for modern tokamaks were also discussed. In particular, the report by Mikhail Zharkov (Krasnaya Zvezda JSC) discussed the design and the first test results of a lithium divertor model for the KTM tokamak (Kazakhstan) and the T-15MD tokamak. Alexander Zakharenkov from MPEI presented the results of tests of a promising water-dispersion cooling system for divertor modules.

The conference participants noted the high level of the event.
