Compact DT fusion spherical tori at modest fields [PDF]

, 1985
A spherical torus is obtained by retaining only the indispensable components on the inboard side of a tokamak plasma, such as a cooled, normal conductor that carries current to produce a toroidal magnetic field.

Observation of a new pedestal stability regime in MAST Upgrade H-mode plasmas

Nuclear Fusion
The first pedestal stability and structure analysis on the new MAST Upgrade (MAST-U) spherical tokamak H-mode plasmas is presented. Our results indicate that MAST-U pedestals are close to the low toroidal mode number ( n ) peeling branch of the peeling ...

Design of a low frequency, density profile reflectometer system for the MAST-U spherical tokamak [PDF]

Validated and accurate edge profiles (temperature, density, etc.) are vitally important to the Mega Ampere Spherical Tokamak Upgrade (MAST-U) divertor and confinement effort.

Overview of ST40 results and future: expanding the physics basis of high-field spherical tokamaks

Nuclear Fusion
The goal of the ST40 programme is to explore the physics of high-field spherical tokamaks (STs), to validate empirical and theoretical models and, hence, to build confidence in predictions required to support the design of future generations of STs. ST40

Plasma Current Start-up by ECW and Vertical Field in the TST-2 Spherical Tokamak

Plasma current start-up and ramp-up to 10kA have been demonstrated in the TST-2 spherical tokamak without the use of the central solenoid. Only the electron cyclotron wave (ECW) and the outer equilibrium field coils are used. The plasma current evolution
