Internal transport barriers in tokamak plasmas* [PDF]
Plasma Physics and Controlled Fusion, 2002 Internal transport barriers in tokamak plasmas are explored in order to improve confinement and stability beyond the reference scenario, used for the ITER extrapolation, and to achieve higher bootstrap current fractions as an essential part of non-inductive current drive.

Neutral Beam Coupling with Plasma in a Compact Fusion Neutron Source
Applied Sciences, 2022 FNS-ST is a fusion neutron source project based on a spherical tokamak (R/a = 0.5 m/0.3 m) with a steady-state neutron generation of ~1018 n/s. Neutral beam injection (NBI) is supposed to maintain steady-state operation, non-inductive current drive and ...

Experimental Investigations of Magnetohydrodynamic Plasma Jets [PDF]
, 2009 This thesis primarily focuses on understanding the plasma behavior during the helicity injection stage of a pulsed spheromak experiment. Spheromak formation consists of a series of dynamic steps whereby highly localized plasma near the electrodes evolves

Plasma startup patterns in tokamak reactors. [PDF]
Journal of Nuclear Science and Technology, 1983 Plasma startup patterns are studies from the viewpoint of net power loss represented by the total power loss less the a-particle heating power. The existence is shown of a critical temperature of plasma at which the net power loss becomes independent of plasma density.

Orbit effects on impurity transport in a rotating tokamak plasma
, 1988 Particle orbits in a rotating tokamak plasma are calculated from the equation of motion in the frame that rotates with the plasma. It is found that heavy particles in a rotating plasma can drift away from magnetic surfaces significantly faster with a ...

The importance of the toroidal magnetic field for the feasibility of a tokamak burning plasma experiment [PDF]
, 2000 The next step in the demonstration of the scientific feasibility of a tokamak fusion reactor is a DT burning plasma experiment for the study and control of self-heated plasmas. In this paper, the authors examine the role of the toroidal magnetic field on

Coupling Fluid Neutrals to Gyrokinetic Plasma Dynamics for Edge and SOL Turbulence Simulations
Contributions to Plasma Physics, EarlyView.ABSTRACT Accurate modeling of turbulent transport in magnetic confinement fusion devices requires extending first‐principles gyrokinetic simulations from the core to the edge and scrape‐off layer (SOL), where additional physics—particularly plasma–neutrals interactions—must be included.
