After installation of Mo liners in the source NIO1 (Negative Ion Optimization phase 1), hydrogen plasmas in a continuous regime operation (much longer than one hour) are routinely maintained, with more than 1 kW rf power and 0.5 Pa pressure, allowing

The ion source NIO1 (Negative Ion Optimization 1) was developed and installed as a reduced-size model of multi-aperture sources used in neutral beam injectors. NIO1 beam optics is optimized for a 130 mA H- current (subdivided in 9 beamlets) at a Vs=6

Particle model of a cylindrical inductively coupled ion source

Autor: P. Minelli, Francesco Taccogna, Marco Cavenago, Pierluigi Veltri, N. D. Ippolito

Publikováno v: AIP Conference Proceedings.

In spite of the wide use of RF sources, a complete understanding of the mechanisms regulating the RF-coupling of the plasma is still lacking so self-consistent simulations of the involved physics are highly desirable. For this reason we are developin

Particle model of full-size ITER-relevant negative ion source

Autor: Francesco Taccogna, N. D. Ippolito, P. Minelli

Publikováno v: The Review of scientific instruments. 87(2)

This work represents the first attempt to model the full-size ITER-relevant negative ion source including the expansion, extraction, and part of the acceleration regions keeping the mesh size fine enough to resolve every single aperture. The model co

The characterization and optimization of NIO1 ion source extraction aperture using a 3D particle-in-cell code

Autor: Marco Cavenago, P. Minelli, Francesco Taccogna, N. D. Ippolito, Pierluigi Veltri

Publikováno v: The Review of scientific instruments. 87(2)

The geometry of a single aperture in the extraction grid plays a relevant role for the optimization of negative ion transport and extraction probability in a hybrid negative ion source. For this reason, a three-dimensional particle-in-cell/Monte Carl

The requirement of a neutral beam injection system with hydrogen or deuterium beam energy up to 1 MeV for the ITER project has recently triggered new research on negative ion sources, from production to acceleration and neutralization before the inje
