Description
At GSI, the CAPRICE ECR Ion Source (ECRIS), installed at the High Charge State Injector (HLI), delivers continuous-wave (cw) metallic ion beams for studies and experiments, carried out by nuclear physics, materials research, and superheavy elements groups. To meet the demand for ions from metals and solid compounds, thermal evaporation via resistively heated ovens is employed.
The use of a hot tantalum liner, inserted into the plasma chamber, has been validated for the efficient production of high charge state ion beams from rare isotopes, such as 48Ca10+ with high intensity and low material consumption. Recent results from the latest beam run demonstrate increased beam intensity, stability and reduced material consumption.
Furthermore, the hot liner helps mitigate metallic buildup on ceramic surfaces, enabling stable operation at high intensities with minimal disruptions. Results from operations with 54Cr and 55Mn confirm the effectiveness of the hot liner in enhancing operational stability.
