Plasma Physics and Controlled Fusion, 2020 We demonstrate 2D reconstructions of the fast-ion velocity distribution from two-view fast-ion D-alpha (FIDA) measurements at the EAST tokamak. By expressing the distribution in a basis relying on the fast-ion slowing-down process in fusion plasmas, the ...

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.

Requirements and modelling of fast particle injection in RFX-mod tokamak plasmas [PDF]
, 2017 The planned upgrade of the RFX-mod device is a good opportunity to widen the operational space of the machine, in both RFP and tokamak configurations. Installation of a power neutral beam injector is also envisaged and a NB system compatible with RFX-mod,

PLT neutral beam injection systems [PDF]
, 1979 A brief description of the Princeton Large Torus (PLT) neutral beam injection system is given and its performance characteristics are outlined. A detailed operational procedure is included, as are some tips on troubleshooting. Proper operation of the source is shown to be a crucial factor in system performance.

Transport Simulasion in a Burning Tokamak Plasma [PDF]
, 1992 A one-dimensional tokamak transport code (TASK/TR) has been developed to analyze the evolution of a burning plasma accompanied with fusion reaction. This code deals with the electrons, deuterons, tritons, thermalized α particles, fast α particles and ...

Observation of Alfvén Eigenmodes driven by off-axis neutral beam injection in the TCV tokamak
Plasma Physics and Controlled Fusion, 2020 Fast-particle driven Alfvén Eigenmodes have been observed in low-collisionality discharges with off-axis neutral beam injection (NBI), electron cyclotron resonance heating (ECRH) and a reduced toroidal magnetic field.

TPX Neutral Beam injection system design [PDF]
15th IEEE/NPSS Symposium. Fusion Engineering, 2002 The existing Tokamak Fusion Test Reactor (TFTR) Neutral Beam system is proposed to be modified for long pulse operation on the Tokamak Physics Experiment (TPX). Day one operation of TPX will call for one TFTR beamline modified for 1000 second pulse lengths oriented co-directional to the plasma current. The system design will be capable of accommodating

Edge momentum transport by neutrals: an interpretive numerical framework [PDF]
, 2017 Due to their high cross-field mobility, neutrals can contribute to momentum transport even at the low relative densities found inside the separatrix and they can generate intrinsic rotation.
