New start for spherical tokamak

Physics World, 2015
Physicists at the Princeton Plasma Physics Laboratory (PPPL) in the US are set to start experiments on a novel kind of fusion reactor known as a spherical tokamak.

Prospects for pilot plants based on the tokamak, spherical tokamak and stellarator

Nuclear Fusion, 2011
A potentially attractive next-step towards fusion commercialization is a pilot plant, i.e. a device ultimately capable of small net electricity production in as compact a facility as possible and in a configuration scalable to a full-size power plant. A key capability for a pilot-plant programme is the production of high neutron fluence enabling fusion

The Mega Amp Spherical Tokamak

Fusion Engineering and Design, 1999
Results from START at Culham have been very impressive and have triggered the construction of several new Spherical Tokamaks (R/a ≤ 1.5), including the Mega Amp Spherical Tokamak (MAST), which was given EURATOM approval in April 1996. MAST (R = 0.7 m, a = 0.5 m, k ∼ 2, I p ≤ 2 MA) is twice the size of START and will allow plasmas with cross-section ...

Steady state operation of spherical tokamaks

Nuclear Fusion, 2000
For a fusion power plant to be economically and technologically attractive, it should be as compact as possible and capable of `steady state' operation. One approach is based upon the spherical tokamak (ST) concept. This configuration features many of the qualities of the conventional aspect ratio tokamak, such as good confinement and MHD stability ...

Proposal on LHCD Experiments in Spherical Tokamaks

AIP Conference Proceedings, 2009
A new approach for LHCD problem in spherical tokamaks (ST) is investigated, when the LH waves are slowed down in poloidal rather than toroidal direction by a grill antenna oriented vertically. Characteristics of wave propagation are found by ray tracing technique modernized for the case of strongly inhomogeneous plasma in ST.

Development of the spherical tokamak power plant

Fusion Engineering and Design, 2002
Abstract The design of a power plant based on the spherical tokamak (ST) is being developed in order to explore the potential advantages of the ST for power production. The ST power plant operates at a low aspect ratio of typically 1.4–1.6, which allows operation at high beta.

Diagnostic Developments for the Mast Spherical Tokamak

2002
MAST1 is a relatively new spherical tokamak (ST) with plasma cross-section and parameters comparable to those of ASDEX-U and DIII-D but at much lower field (0.5T) and aspect ratio (∼1.3). The plasma is heated with neutral beams and two 60GHz RF schemes (ECRH and, under development, electron Bernstein wave heating). The aims of MAST are to contribute to
