Proceedings of 16th International Symposium on Fusion Engineering, 2002
START continues to provide key results on the 'spherical tokamak' concept. This paper outlines the engineering solutions adopted to overcome problems of space restrictions in a very low aspect ratio tokamak, whilst providing high performance at low cost.

Bootstrap Current in Spherical Tokamaks
Plasma Science and Technology, 2003Variational principle for the neoclassical theory has been developed by including a momentum restoring term in the electron-electron collisional operator, which gives an additional free parameter maximizing the heat production rate. All transport coefficients are obtained including the bootstrap current.

Development of Next-Generation Spherical Tokamak Concept. The Globus-3 Tokamak
Физика плазмы, 2023The concept of next-generation spherical tokamak is being considered: the Globus-3 project,which, in its characteristics, is compatible with the infrastructure existing at the Ioffe Institute, but differsfrom the currently operating Globus-M2 tokamak in the stronger toroidal magnetic field (1.5–3.0 T) andincreased duration of plasma discharge.

Spherical tokamak volume neutron source
Fusion Engineering and Design, 1999Abstract Details are discussed of a volume neutron source for testing assemblies such as blanket sections in a 14 MeV neutron environment. This neutron source is based on the spherical tokamak. The experimentally confirmed ability of the spherical tokamak to reach very high plasma pressures makes it ideally suited as the basis for a very compact ...

'Natural elongation' of spherical tokamaks
Nuclear Fusion, 1992The variation of the elongation of axisymmetric plasma columns in vertical equilibrium magnetic fields is investigated as a function of the aspect ratio using the Solov'ev equilibrium model and the principle of virtual ...

Progress on spherical tokamaks
Plasma Physics and Controlled Fusion, 1994The history of low-aspect-ratio 'spherical' tokamak research is described and the advantages claimed for the concept are outlined and compared with experimental results from the START device and elsewhere. Further development of the spherical tokamak, and its potential for a materials test facility or ultimately a fusion plant, are discussed.
