Tokamak and Spherical Tokamak Research in Japan

Fusion Science and Technology, 2007
Japanese tokamak and spherical tokamak (ST) research programs are described. Tokamak research will focus on steady state high β (β N = 3.5-5.5) research on JT-60SA (formerly NCT) in support of ITER and DEMO. JT-60SA will also serve as the Satellite Tokamak under the JA-EU Broader Approach framework. ST research has been reorganized as the All-Japan ST

The START spherical tokamak

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, 2003
Variational 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.

The Mega Amp Spherical Tokamak

Proceedings of 16th International Symposium on Fusion Engineering, 2002
A Mega Amp Spherical Tokamak (known as MAST) is proposed to be constructed at Culham Laboratory. The aim is to continue the highly successful tight aspect ratio work pioneered on the START machine at Culham.

Development of Next-Generation Spherical Tokamak Concept. The Globus-3 Tokamak

Физика плазмы, 2023
The 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, 1999
Abstract 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 ...
