Laser diagnostics for negative ion source optimization: insights from SPIDER at the ITER Neutral Beam Test Facility
R. Agnello, M. Barbisan, R. Pasqualotto +4
The ITER Heating Neutral Beams (HNBs) require large, high-energy H/D atom beams (285/330 A/m^2 extracted current density, and 1/0.87 MeV acceleration energy, respectively for H and…
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…
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…
Continuous pulse advances in the negative ion source NIO1
M. Barbisan, R. Agnello, M. Cavenago +23
Consorzio RFX and INFN-LNL have designed, built and operated the compact radiofrequency negative ion source NIO1 (Negative Ion Optimization phase 1) with the aim of studying the pr…
Development and first operation of a Cavity Ring Down Spectroscopy diagnostic in the negative ion source SPIDER
M. Barbisan, R. Pasqualotto, R. Agnello +6
The Neutral Beam Injectors of the ITER experiment will rely on negative ion sources to produce 16.7 MW beams of H/D particles accelerated at 1 MeV. The prototype of these sources w…
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…
