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

SIMULATION OF NEUTRAL BEAM INJECTION IN POSITIVE AND NEGATIVE TRIANGULARITY TOKAMAKS

Anales (Asociación Física Argentina), 2023
In this paper the dynamics of high energy charged particles in negative and positive triangularity tokamaks is studied through the simulation of a neutral beam injection on analytical MHD equilibria using the exact orbit code FOCUS.

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 ...

Neutral-beam injection calculations for torsatrons [PDF]

Nuclear Fusion, 1980
A numerical investigation of the effectiveness of neutral-beam heating in two torsatron-type devices has been undertaken. A modified version of a well-known deposition and orbit code was used for this purpose. It was found that, for beam currents within the applicable range of the model, neutral beams can efficiently heat either a 'classical' torsatron

Neutral Beams for Neutron Generation in Fusion Neutron Sources

Atoms, 2022
Neutral beam injection is supposed to be the main source of high-energy particles, driving non-inductive current and generating primary neutrons in fusion neutron sources design based on tokamaks.

Neutral Particle Beam Production and Injection [PDF]

, 1983
Intense neutral beams are used to heat, fuel, adjust electric potentials, and diagnose fusion plasmas. They may be used to sustain currents in plasmas. We shall comment on some of the ways that atomic physics enters into the design, diagnosis, and application of neutral beam systems.

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
