The production of multiply charged ions at medium-high intensity in Electron Cyclotron Resonance Ion Sources requires a trade-off between the plasma density ne and the ion confinement time τi (well known scaling-laws state that I∝ ne / τi while "∝ neτi ). Any additional boost of currents with respect to the state of the art (e.g. tens or hundreds μA of Ar14+, Xe34+, etc.), – especially for...

Neutral Beam Injectors (NBI) based on negative ion conversion are fundamental to increase the plasma temperature in magnetic confinement fusion devices.. In the framework of the accompanying activities in support to the ITER NBI test facility a relatively compact radiofrequency (RF) ion source, named NIO1 (Negative Ion Optimization phase 1) is being developed and tested in Padua, Italy, in...

Conclusive discussion on applications shown at the conference. Perspectives of ion sources for hydrogen and deuterium, and other elements (negative ion, and/or positive). Perspective of (new) collaborations. Minutes prepared by convener(s) may be posted on the website, as well as short presentations (3 slide max) received for the discussion.

Low pressure ExB partly (electron) magnetized plasmas plays a key role not only in different plasma-based devices, such as Hall-effect thruster and negative ion source. In the first, the magnetic field allows a better electron confinment increasing the propellant ionization and ion acceleration efficiencies, while in the second the magnetic filter field allows the electron temperature and...

Future publication of the conference results can be discussed, as well as ideas for new workshop themes in the Accelerator Application Network of the EUCARD2 project, and general questions. Closing remarks will follow. Minutes prepared by convener(s) may be posted on the website, as well as short presentations (3 slide max) received for the discussion.
