The vacuum arc ion source VARIS, based on the MEVVA IV (MEtal Vapor Vacuum Arc) ion source, has been developed at GSI in 2004 especially for production of high current $^{238}$U$^{4+}$ ion beams for synchrotron operation. Compared to the MEVVA IV ion source the VARIS has a number of improved characteristics: higher emission current density, better vacuum conditions, better pulse-to-pulse...
The Irfu/SACM at Saclay is in charge of developing and building the ion source and the low energy line or the proton linac of the FAIR accelerator complex (Facility for Antiproton and Ion Research) located at GSI (Darmstadt) in Germany. The FAIR Facility will deliver stable and rare isotope beams covering a huge range of intensities and beam energies for experiments in the fields of atomic...
As the main H$^{-}$ ion source for the accelerator complex, magnetron ion sources have been used at Fermilab since the 1970’s. At the offline test stand, new R&D is carried out to develop and upgrade the present magnetron-type sources of H$^{-}$ ions of up to 80 mA and 35 keV beam energy in the context of the Proton Improvement Plan. The aim of this plan is to provide high-power proton beams...
Emittance of multiply-charged heavy ion beam extracted from ECR ion source should be matched with the acceptance of the following low energy beam transport (LEBT) and accelerator in order to improve transport efficiency. The more beam brightness increases, the more important space-charge effect is because it induces the spatial aberration of beam optics components, e.g. dipole magnets and...
A novel polarization technique had been successfully implemented for the RHIC polarized H$^-$ ion source upgrade to higher intensity and polarization. In this technique a proton beam inside the high magnetic field solenoid is produced by ionization of the atomic hydrogen beam (from external source) in the He-gas ionizer cell. Further proton polarization is produced in the process of polarized...
