Interpretation of suprathermal emission at deuteron cyclotron harmonics from deuterium plasmas heated by neutral beam injection in the KSTAR tokamak [PDF]

Nuclear Fusion, 2019
Intense bursts of suprathermal radiation, with spectral peaks at
 frequencies corresponding to the deuteron cyclotron frequency in the outer
 midplane edge region, are often detected from deuterium plasmas in the KSTAR
 tokamak ...

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 ...

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.

Fast forward modeling of neutral beam injection and halo formation including full Balmer-α emission prediction at W7-X

Journal of Instrumentation, 2023
A full collisional-radiative (CR) neutral beam injection model based on Gaussian pencil (Gausscil) beams and a diffusive CR neutral halo model are presented. The halo is a neutral cloud around the neutral beam forming due to multiple charge exchange (CX)

Neutral beam injection for fusion reactors: technological constraints versus functional requirements

Nuclear Fusion, 2021
In this paper we look at the technological constraints of neutral beam injection (NBI) systems and compare them with the functional requirements that NBI has in the various envisaged plasma scenarios for tokamak fusion reactors of the DEMO and fusion ...

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.
