Rep. 52, 531–542 (2026). https://doi.org/10.1134/S1063780X26600404 The operation of the GOL-NB facility is supported by the Ministry of Science and Higher Education of the Russian Federation within the framework of the state research plan. The development of a system for additional plasma heating at the ion cyclotron resonance frequency is being carried out as part of the work plan for the event “Experimental verification of effective plasma containment methods in existing and prospective linear systems” of the federal project “Development of technologies for controlled thermonuclear fusion and innovative plasma technologies” of the comprehensive program “Development of equipment, technologies, and scientific research in the field of nuclear energy in the Russian Federation for the period up to 2025.”

N2 - The possibility of implementing the magnetic beach method in the GOL-NB facility is analyzed. Based on the analysis of plasma transparency regions and numerical modeling in two-dimensional cylindrical geometry, the possibility of excitation of an Alfvén wave in GOL-NB plasma has been studied. For heating, it is proposed to use electromagnetic waves with a frequency of 13.56 MHz (resonance with protons in a magnetic field of 0.89 T). The antenna will be placed in a magnetic field of 1.3 T. It is shown that heating can be realized up to plasma densities of ~1019 m–3, which will make it possible to significantly expand the range of plasma parameters available for the GOL-NB experiment. At a design density of 3 × 1019 m–3 the introduction of RF power can help to heat the plasma periphery and improve the retention of hot ions in the trap.
