Oxide Target Designs for High Primary Beam Intensities for Future Radioactive Ion Beam Facilities

Oxide targets used nowadays in ISOL facilities can only accommodate up to a few kW incoming beam power because of the targets’ moderate operation temperatures and their low thermal conductivities. A generic design to accommodate a 100 kW, 1 GeV proton beam, used as baseline parameters in the ongoing EURISOL‐DS project, along with the numerical and experimental tools required for its validation, are reported here. We provide some details on these high‐power composite oxide‐refractory metal targets and on the proposed arrangement in several sub‐units merging into a single ion source.
