Modeling inductive radio frequency coupling in powerful negative hydrogen ion sources: optimizing the RF coupling
Dominikus Zielke, Stefan Briefi, Ursel Fantz
In the fusion experiment ITER powerful neutral beam injection (NBI) systems will be used. The NBI's core component is a negative hydrogen ion source, which is based on a modular co…
Lessons learned after three years of SPIDER operation and the first MITICA integrated tests
D. Marcuzzi, V. Toigo, M. Boldrin +139
ITER envisages the use of two heating neutral beam injectors plus an optional one as part of the auxiliary heating and current drive system. The 16.5 MW expected neutral beam power…
H- Beam formation simulation in negative ion source for CERN's Linac4 accelerator
Anna Vnuchenko, Jacques Lettry, Dirk Wünderlich +5
The caesiated surface negative ion source is the first element of CERN's LINAC4 a linear injector designed to accelerate negative hydrogen ions to 160 MeV. The IS03 ion source is o…
Numerical study of RF power coupling in fusion-relevant single- and multi-driver H ion sources
Dominikus Zielke, Stefan Briefi, Ursel Fantz
ITER's large and powerful neutral beam injection system is based on an ion source utilizing a modular concept, where eight cylindrical drivers are attached to one common expansion…
Influence of the magnetic filter field topology on the beam divergence at the ELISE test facility
M. Barbisan, U. Fantz, D. Wünderlich
The ELISE test facility hosts a RF negative ion source, equipped with an extraction system which should deliver half the current foreseen for the ITER Neutral Beam Injector, keepin…
Beam characterization by means of emission spectroscopy in the ELISE test facility
M. Barbisan, F. Bonomo, U. Fantz +1
The ELISE test facility at IPP Garching hosts a RF H-/D- ion source and an acceleration system. Its target is to demonstrate the performance foreseen for the ITER NBI system in ter…
First hydrogen operation of NIO1: characterization of the source plasma by means of an optical emission spectroscopy diagnostic
M. Barbisan, C. Baltador, B. Zaniol +6
NIO1 is a compact and flexible radiofrequency H- ion source, developed by Consorzio RFX and INFN-LNL. Aim of the experimentation on NIO1 is the optimization of both the production…
A novel hydrogenic spectroscopic technique for inferring the role of plasma-molecule interaction on power and particle balance during detached conditions
K Verhaegh, B Lipschultz, C Bowman +13
Detachment, an important mechanism for reducing target heat deposition, is achieved through reductions in power, particle and momentum; which are induced through plasma-atom and pl…
Performance analysis of a 2.45 GHz microwave plasma torch for CO decomposition in gas swirl configuration
F. A. D'Isa, E. A. D. Carbone, A. Hecimovic +1
Microwave plasmas are a promising technology for energy-efficient CO valorization via conversion of CO into CO and O using renewable energies. A 2.45 GHz microwave…
Analysis of the C (d-a) Swan bands as a thermometric probe in CO microwave plasmas
Emile Carbone, Federico D'Isa, Ante Hecimovic +1
The optical emission spectra of high pressure CO microwave plasmas are usually dominated by the C Swan bands. In this paper, the use of the C Swan bands for estimating…
