The spherical torus or spherical tokamak (ST) is a member of the tokamak family with its
aspect ratio (A= R 0/a) reduced to A∼ 1.5, well below the normal tokamak operating range …

The Globus-M spherical tokamak has demonstrated practically all of the project objectives
during the 15-year period of operation. The main factor limiting further progress in plasma …

Nuclear power is low carbon and reliable, but in recent years it has struggled to play a
strong role in global plans for electricity generation in the 21st century. Many of those …

The work presents the results of the energy confinement study carried out on the compact
spherical tokamak Globus-M2 with a toroidal magnetic field as high as 0.8 T. A reproducible …

Hot ion mode was recently achieved at the Globus-M2 spherical tokamak when the toroidal
magnetic field was as high as 0.9 T and plasma current 0.35 MA. The injection of two neutral …

A multi-diagnostic study of the fast ion losses and redistribution during toroidal Alfvén
eigenmodes at the Globus-M and Globus-M2 spherical tokamaks was performed. Mode …

The first experiments on noninductive current drive (CD) using lower hybrid waves in a
spherical tokamak are described. Waves at 2.45 GHz were launched by a 10 waveguide grill …

The behaviour of the fast particle population during 18 keV hydrogen and 26 keV deuterium
neutral beam injection in deuterium plasmas is investigated. Experiments reveal large fast …

Abstract Globus-M2—a new 1-Tesla spherical tokamak—was recently launched. The main
features and research directions of this machine in scope of fusion–fission reactor …

Abstract The SMall Aspect Ratio Tokamak (SMART) device is a new compact (plasma major
radius R geo≥ 0.40 m, minor radius a≥ 0.20 m, aspect ratio A≥ 1.7) spherical tokamak …
