Description
The heavy ion accelerator facility GSI (Darmstadt, Germany) is internationally recognized as a unique center for research, offering over 100 different ion species derived from 34 chemical elements, ranging from hydrogen to uranium. Scientific experiments utilizing high-energy ion beams provided by the heavy ion synchrotron SIS-18 are typically served by pulsed high-current ion sources. Currently, 28 elements (8 gaseous and 20 metallic) are available for operation using high-current ion sources. Metallic ion beams are generated with vacuum arc-driven ion sources (VARIS).
The improvement and development of VARIS is continuously pursued in parallel with routine accelerator operation. In recent years, VARIS development has focused on the production of new elements and ion species as requested by experimental programs. This paper presents the results of high-current beam development for the following ion species: 45Sc²⁺, 94Mo³⁺, 100Mo²⁺/³⁺, 112Sn²⁺, 141Pr³⁺, 160Gd³⁺, 170Er³⁺, 186W³⁺/⁴⁺, and 198Pt⁴⁺. In addition, an outlook on future development plans is provided.
