Improved Bevatron Local Injector Ion Source Performance

Ion-Source Modeling and Improved Performance of the CAMS High-Intensity Cs-Sputter Ion Source

The interior of the high-intensity Cs-sputter source used in routine operations at the Center for Accelerator Mass Spectrometry (CAMS) has been computer modeled using the program NEDLab, with the aim of improving negative ion output. Space charge effects on ion trajectories within the source were modeled through a successive iteration process involving the calculation of ion trajectories throug...

A New End-Hall Ion Source with Improved Performance

End-Hall ion sources have been used for almost 20 years in the optical coating industry for ion assisted deposition (IAD) and substrate pre-clean. In these applications, end-Hall ion sources have several desirable performance characteristics. They produce a large current of low energy ions, and they distribute the ions uniformly over a large coverage area. The sources can operate on either argo...

Caesium influence on plasma parameters and source performance during conditioning of the prototype ITER neutral beam injector negative ion source

Systematic Langmuir probe measurements were performed during the caesium (Cs) conditioning of the IPP prototype negative hydrogen ion source. Conditioning consists of slowly injecting caesium into the source in order to increase the extracted negative ion current and minimize the co-extraced electrons. This process usually takes several days. Measurements were taken near the plasma grid where t...

MonPS09 Heavy ion injector based on ECR ion source for RISP linac

Ion Beam Properties and Their Diagnostics for Ecr Ion Source Injector Systems

Electron Cyclotron Resonance (ECR) ion sources are essential components of heavy-ion accelerators due to their ability to produce the wide range of ions required by these facilities. The ever-increasing intensity demands have led to remarkable performance improvements of ECR injector systems mainly due to advances in magnet technology as well as an improved understanding of the ECR ion source p...
