2D electromagnetic simulations of RF heating via inductive coupling in the SPIDER device
D. López-Bruna, P. Jain, M. Recchia +6
SPIDER is the prototype ion source of MITICA, the full-size neutral beam heating system conceived for the ITER tokamak. It includes eight drivers to heat and sustain the inductivel…
Spider Ion Source and Extraction Power Supplies -- An update of the design after four years of operation
A. Shepherd, M. Bigi, R. Casagrande +6
SPIDER, the ion source prototype for ITER neutral beam injectors, has been in operation since 2018. The experiment includes a system of Ion Source and Extraction Power Supplies (IS…
Overview on electrical issues faced during the SPIDER experimental campaigns
Alberto Maistrello, Matteo Agostini, Marco Bigi +39
SPIDER is the full-scale prototype of the ion source of the ITER Heating Neutral Beam Injector, where negative ions of Hydrogen or Deuterium are produced by a RF generated plasma a…
Conceptual design of the Gas Injection and Vacuum System for DTT NBI
P. Agostinetti, S. Dal Bello, F. Dinh +9
The Divertor Tokamak Test (DTT) is a new experimental facility whose construction is starting in Frascati, Rome, Italy; its main goals are improving the understanding of plasma-wal…
Numerical and experimental investigations of a microwave interferometer for the negative ion source SPIDER
R. Agnello, R. Cavazzana, I. Furno +4
The electron density close to the extraction grids and the co-extracted electrons represent a crucial issue when operating negative ion sources for fusion reactors. An excessive el…
Measure of negative ion density in a large negative ion source using Langmuir probes
Carlo Poggi, Monica Spolaore, Marco Barbisan +7
Neutral Beam Injectors (NBIs) based on negative ions are the workhorses of future fusion reactors, such as ITER, which they are expected to provide with up to \SI{33}{MW} of power…
Characterization of cesium and H-/D- density in the negative ion source SPIDER
Marco Barbisan, R. Agnello, L. Baldini +6
The Heating Neutral Beam Injectors (HNBs) for ITER will have to deliver 16.7 MW beams of H/D particles at 1 MeV energy. The beams will be produced from H-/D- ions, generated by a r…
Negative ion density in the ion source SPIDER in Cs free conditions
M. Barbisan, R. Agnello, G. Casati +5
The SPIDER experiment, operated at the Neutral Beam Test Facility of Consorzio RFX, Padua, hosts the prototype of the H-/D- ion source for the ITER neutral beam injectors. The maxi…
Characterization of Cs-free negative ion production in the ion source SPIDER by Cavity Ring-Down Spectroscopy
M. Barbisan, R. Agnello, G. Casati +3
The Neutral beam Injectors of the ITER experiment will be based on negative ion sources for the generation of beams composed by 1 MeV H/D particles. The prototype of these sources…
