The 21st All-Russian Conference "High-Temperature Plasma Diagnostics" was held in Sochi, bringing together the country's leading specialists in the field of fusion research. Researchers actively participated in the conference. Institute of Physics and Mechanics.
The conference provided a platform for sharing experiences in the development and application of diagnostic methods necessary for the implementation of large-scale projects. Researchers from the Higher School of Fundamental Physics Research, the Higher School of Mechanics and Control Processes, and the Scientific Laboratory for Advanced Methods of Spherical Tokamak Plasma Research presented plasma diagnostic methods developed at the university, as well as the results of comprehensive thermomechanical and electromagnetic modeling of diagnostic systems.
Dmitry Korobko, a postgraduate student at the Higher School of Physics and Technology and a research assistant at the Scientific Laboratory for Advanced Methods of Spherical Tokamak Plasma Research, presented the results of spectroscopic diagnostics of peripheral plasma using neutral helium injection.
Arseniy Tokarev, a graduate student at the Higher School of Physics and Physical Research, presented a paper titled "Ray Tracing Calculation for Doppler Backscatter Diagnostics on the Globus-M2 Tokamak." His paper described the operating principle and features of specialized software developed at SPbPU for analyzing and correctly interpreting Doppler backscatter diagnostic data. It should be noted that In the fall semester of the 2025/26 academic year, Arseniy was awarded a personal scholarship from the B. P. Konstantinov PhysMech Institute.
Postgraduate student and research assistant Kirill Kukushkin, Professor Elizaveta Kaveeva, Professor Vladimir Rozhansky, and Associate Professor Ilya Senichenkov joined the author team of the report "Study of the Formation of a High-Density Region from a Strong Magnetic Field Near the Globus-M2 Tokamak Diverter," presented by Polytechnic University's partner, the A.F. Ioffe Physicotechnical Institute. The report presented the results of a study on the formation of a high-density region from a strong magnetic field near the tokamak's inner divertor.
At the section “Engineering issues of plasma diagnostics” a series of reports were presented by the staff of the Higher School of Microelectronics and Control Systems andPISh "Digital Engineering"Mechanical engineering research focuses on developing methods for analyzing the strength and durability of structures under extreme conditions.
Alexey Novokshenov, Associate Professor at the Higher School of Physics and Control Sciences and Senior Researcher at the Computer Engineering Center, presented a paper titled "Complex Modeling and Optimization of the HFS-Reflectometry Diagnostic System for the ITER Tokamak."
Philipp Shadelko, a research engineer at the Digital Engineering in Nuclear and Fusion Energy Research and Education Center, presented the results of calculations performed for a digital twin of elements of one of ITER's diagnostic ports, which substantiated the operability of the proposed designs.
Viktor Modestov, a leading programmer at the Higher School of Mathematics and Control Sciences, an associate professor at the Higher School of Nuclear and Thermal Energy at the Institute of Economics, and director of the Digital Engineering in Nuclear and Fusion Energy Research and Education Center, presented a paper titled "Ratcheting Effects under High-Temperature Cyclic Loading of ITER Fusion Reactor Diagnostic Components." The paper analyzed the potential for unlimited growth of inelastic strain in the diagnostic system.
Anna Luiza Andreeva, a master's student and engineer at HSE, also presented a paper entitled "Quasi-Power-Free Magnetic Systems with a Strong Field for Plasma Diagnostics and Containment Devices."
Viktor Modestov, Ivan Kiriyenko, and Alexey Kudryavtsev and Alexander Lobachev, research engineers from the Digital Engineering in Nuclear and Fusion Energy Research and Education Center, joined the team of authors for the keynote presentation at the conference, "Achievements in the Development and Production of ITER Diagnostic Equipment at the INP SB RAS."
