Service Areas PIG ion source service area In 2012 the PIG ion source service area was set up with new room modules. Inside the ion sources are serviced. Single use wear parts are changed and if required [...] where all parts of the ion source are being accessed very easy. On top of the modul room there are cabinets with different parts for the PIG ion source service. High current ion sources service area Since [...] service of the ECR ion source and the low energy beam transport line. It is equipped with a basic set of tools, two ultrasonic baths and a few machines needed for the maintenance of the ion source and its

The ion source [...] and to be able to improve the ion source performance. more... Author: R. Hollinger et al. Status of vacuum arc ion source development for injection of high current uranium ion beams into the GSI accelerator [...] beam times at the high current injector at GSI. With the new ion source it was possible to exceed the space charge limit of 15 mA U 4+ ions at the entrance of the linear accelerator (UNILAC) for the very

Vacuum Arc Ion Sources: Charge State Enhancement and Arc Voltage The Metal Vapor Vacuum ion source (MEWA) has been developed for the production of ion beams for a wide range of metal ions. The ion charge states [...] states for most heavy elements created by the high current MEVVA ion source, which typically generates ions with a mean charge state up to three, have to be elevated to higher charge states for accelerator [...] U4+ ions a strong magnetic field and a high arc current has been used at GSI. Both methods increase the arc voltage which in turn influences the electron energy distribution and thus the mean ion charge

Vacuum Arc Ion Sources at GSI Accelerator Facility This work describes recent results of developing high current ion beams of Bi and Au at GSI accelerator facility. Challenges of production of ion beams with [...] with required charge state in vacuum arc discharge ion sources are discussed. The difficulties and limitations occurred due to using of pure Bi and Au materials in the cathodes are described. As a feasible [...] considered. As a significant result, a dramatic improvement in production of high charge state Bi and Au ions using the mixed Bi-Cu (15% Wt.) and Au-Cr (50% Wt.) cathodes, respectively, compare to cathodes from

CURRENT ION SOURCE OPERATION AT THE GSI ACCELERATOR FACILITY Vacuum Arc Ion Sources, Penning Ion Sources, and filament driven Multi Cusp Ion Sources are used for the production of high current ion beams [...] at the high current injector is presented here giving an outline on important ion source data, such as ion beam current, ion beam spectrum, transversal emittance, life time, duty factor, and transmission [...] beams of a variety of metallic and gaseous ions at the GSI accelerator facility.
