Generation of field-reversed configurations via neutral beam injection [PDF]

Nature Communications
We report evidence of successful generation of field-reversed configuration plasmas by neutral beam injection. This is achieved by trapping the steady-state beams in an initial seed plasma, hence providing a direct source of toroidally directed energetic

Sawtooth activities in EAST neutral beam injection plasma

AIP Advances, 2019
Neutral beam injection (NBI) system has been proved to affect sawtooth activities through both producing energetic particles and supplying torque applied to the plasma.

Neutral beam injection for DEMO alternative scenarios

Fusion Engineering and Design, 2021
Abstract Within the current EU pre-conceptual design activities, the reference demonstrative fusion power plant concept relies on ITER-like, pulsed H-mode plasmas (“DEMO1”). Simultaneously, alternative design options are being considered. An example is “Flexi-DEMO”, which is designed for steady-state plasma discharges, but can also be run pulsed at ...

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 ...

BEAMS3D Neutral Beam Injection Model

Plasma Physics and Controlled Fusion, 2014
With the advent of applied 3D fields in Tokamaks and modern high performance stellarators, a need has arisen to address non-axisymmetric effects on neutral beam heating and fueling. We report on the development of a fully 3D neutral beam injection (NBI) model, BEAMS3D, which addresses this need by coupling 3D equilibria to a guiding center code capable

Atomic collisional data for neutral beam modeling in fusion plasmas

Nuclear Fusion, 2023
The injection of energetic neutral particles into the plasma of magnetic confinement fusion reactors is a widely-accepted method for heating such plasmas; various types of neutral beam are also used for diagnostic purposes.

Prediction of Axial Variation of Plasma Potential in Helicon Plasma Source Using Linear Regression Techniques [PDF]

International Journal of Mathematical, Engineering and Management Sciences, 2020
Analytical expressions are used frequently for the determination and analysis of plasma parameters. Instead of relying on analytical expressions, the proposed method uses regression techniques supplemented with experimental data for the selected ...
