This paper presents recent activities covering different plasma fields, from both theoretical
and experimental point of views. An overview of the present interests of the scientific …

We have performed a study of several cesium oven designs. A comparison between
recirculating (or sticking-wall) and collimating (or re-emitting-wall) ovens is made in order to …

Negative hydrogen (H−) ion sources are operated with Cs injection to reduce coextracted
electron current. Injected Cs atoms adhere on the surface of the electrode with extraction …

Investigation in improving the Cs-free negative hydrogen ion production with short-pulse low
power in the afterglow of pulse-power-modulated plasma sources - IOPscience Skip to content …

An advanced chemical model, based on the state-to-state approach, is applied to the
modeling of a multicusp negative ion source. Simulations are performed with the GPKin …

Negative-ion sources are of considerable interest for applications such as materials
processing and neutral beam injection for magnetic confinement fusion. The efficient …

To efficiently generate H− ions from positive atomic or molecular hydrogen beams injected
onto a solid surface, it has been suggested to use a material with a low-work function as the …

Negative hydrogen ion sources (NHISs) based on surface production with cesium (Cs)
seeded can fulfill the demanded parameters for neutral beam injection systems for ITER. In …
