Improvement of Converter Surface Plasma Sources
V. Dudnikov
A large volume surface plasma source (SPS) with a biased converter was developed for the Los Alamos linear accelerator. A large gas-discharge chamber with a multipole magnetic wall…
Carbon Film in Radio Frequency Surface Plasma Source with Cesiation
Vadim Dudnikov, B. Han, S. Murray +5
It is assumed that persistent cesiation in the SNS RF SPS is related to deposition of carbon film on the collar converter. The work function dependence for graphite with alkali dep…
Development of charge-exchange injection at the Novosibirsk Institute of Nuclear Physics and around the World
Vadim Dudnikov
The study of charge-exchange injection of protons into accelerators started in 1960 at the Institute of Nuclear Physics of the Siberian Branch of Russian Academy of Science, as pro…
Polarized Negative Ion Source with Multiply Sphericaly Focusing Surface Plasma Ionizer
V. Dudnikov, A. Dudnikov
It is proposed one universal H-/D- ion source design combining the most advanced developments in the field of polarized ion sources to provide high-current high-brightness ion beam…
RF Positive Ion Source with Solenoidal Magnetic Field
V. Dudnikov, R. P. Johnson, B. Han +8
A positive ion source with RF discharge in solenoidal magnetic field is described. In this paper we present an overview of positive ion production in saddle antenna (helicon discha…
Modern High Intensity H- Accelerator Sources
Vadim Dudnikov
A review of modern high intensity H- ion sources for accelerators is presented. The cesiation effect, a significant enhancement of negative ion emission from gas discharges with de…
