Abstract

This paper highlights the most important results achieved at the spherical tokamak Globus-M2 with a high magnetic field. This paper also covers the most important topics of fusion research: thermal energy confinement in regimes with neutral beam injection, toroidal Alfvén eigenmode and correspondent fast ions confinement issues, L-H transition, turbulence suppression and edge-localized modes' behavior, experimental and theoretical study of regimes with nitrogen seeding that allow to significantly reduce thermal loads on the divertor plates, and experiments and simulations of lower hybrid current drive. The research results provide the basis for the next step toward a fusion neutron source—the development of the Globus-3 spherical tokamak. [ABSTRACT FROM AUTHOR]

Abstract

The results of measuring the electron temperature and density spatial distributions in plasma of the Globus-M2 tokamak using the Thomson scattering diagnostics are presented. The diagnostics provides measurements throughout the entire tokamak discharge, starting from time of gas breakdown. The Thomson scattering data were analyzed in order to determine the positions of the last closed flux surface, the plasma magnetic axis, and the radius of inversion during the saw-tooth oscillations. The results of measurements performed during the internal reconnection of magnetic field lines are presents, as well as the dynamics of spatial distributions of electron temperature, density and pressure during the plasma transition to the H-mode. The results of measuring the electron temperature distribution in the scrape-off layer using the Thomson scattering diagnostics are also presented for distances up to 4 cm outside the last closed flux surface.

Abstract

The goal of this paper is to assess the possibility of using a new three-ion ICRF heating scheme on the spherical tokamak Globus-M2. In the first place, the operating frequencies and positions of cyclotron harmonics were found. Matching with frequency band of RF system of Globus-M2 was made. The absorption of electromagnetic waves was modeled using a one-dimensional full-wave code. Since the appearance of high-energy particles is expected in the three-ion ICRF scheme of heating special attention is paid to a comparing the estimates for generated particles energies with their confinement in tokamak Globus-M2. Keywords: nuclear fusion, tokamak, high temperature plasma, Globus-M, ICRF heating, three-ion ICRF, H-D-3He plasma.

Abstract

The paper discusses the results of the calibration of two coronaneutron counters used to measure the total neutron yield from the plasma ofthe Globus-M2 tokamak. The calibration was carried out in the experimentalhall of the Globus-M2 facility using an AmBe source. During thecalibration, the source moved at a constant speed around the central solenoid in theequatorial plane of the vacuum chamber, and one of the detectors wasgradually moved away from the tokamak along a line with a constant toroidalangle. The dependence of the calibration coefficient obtained depending distance of the detector from the tokamak is presented. Thecalibration technique made it possible to separate the contributions from the direct neutron flux emitted by the plasma andfrom the flux of neutrons scattered on the elements of the experimentalhall in the detector signal. Keywords: neutron diagnostics, spherical tokamak, neutron yield, neutron counters, thermonuclear fusion\
