Hierarchical Cascade Control Systems for Time-Dependent Dynamical Plants as Applied to Magnetic Plasma Control in D-Shaped Tokamaks

Engineering Proceedings, 2023
The systems of poloidal field coils in D-shaped Tokamaks such as ITER, EAST, JET, ASDEX Upgrade, TCV, GLOBUS-M2, DIII-D, SPARC, IGNITOR, JT-60SA, DEMO-9.1, DEMO-1.6, T-15MD, and TRT are analyzed for their efficiency in the application of plasma position,

Plasma Physics Regimes in Tokamaks with Li Walls [PDF]

, 2003
Low recycling regimes with a plasma limited by a lithium wall surface suggest enhanced stability and energy confinement, both necessary for tokamak reactors. These regimes could make ignition feasible in compact tokamaks. Ignited Spherical Tokamaks (IST),

Modelling for JET Vertical Stabilization System [PDF]

, 2010
Nuclear fusion is, in a sense, the opposite of nuclear fission. Fission, which is a mature technology, produces energy through the splitting of heavy atoms like uranium in controlled chain reactions.

Disruption prediction for future tokamaks using parameter-based transfer learning

Communications Physics, 2023
Tokamaks are the most promising way for nuclear fusion reactors. Disruption in tokamaks is a violent event that terminates a confined plasma and causes unacceptable damage to the device.

Exploring Experimental Isotope Scaling and Density Limit in Tokamak Transport

Plasma
As it turns out, both isotope scaling and density limits are phenomena closely linked to fluid closure. The necessity to include ion viscosity arises for both phenomena. Thus, we have added ion viscosity to our model. The experimental isotope scaling has

Broadening of microwave heating beams in the DIII-D tokamak by edge turbulence

Nuclear Fusion, 2023
We have demonstrated for the first time that turbulent plasma density fluctuations in the edge of the DIII-D tokamak are responsible for substantial broadening of an injected microwave beam by successful quantitative comparison between experimental ...

Tokamaks heated to high beta [PDF]

, 1978
Intense plasma heating (neutral beam, wave, alpha, ...) makes high energy density tokamaks possible. This paper treats the reaction of plasma which is heated to values of beta in the range of 5 to 15%

Poloidal localization of the explosive onset of edge localized modes

Nuclear Fusion, 2023
In ASDEX Upgrade lower single null H-mode plasmas, the onset of the explosive phase of Edge Localized Modes (ELMs) is poloidally localized in the X-point/outer strike point (X/OSP) region. From this location, ELMs develop on average towards the low-field
