Description

A dedicated heavy-ion Radio Frequency Quadrupole (RFQ) accelerator is currently under development at GSI for the SIBAF (Superconducting Ion accelerator as BAsis technology for Fusion research) project. Operating at 108.408 MHz, the RFQ is designed to accelerate heavy ions with a mass-to-charge ratio (A/q) of up to 8.5, from an injection energy of 4 keV/u to a final energy of 300 keV/u. Given that the subsequent main linac utilizes superconducting structures, the RFQ must deliver exceptionally high beam quality to minimize losses and ensure stable operation. This paper details the physics design concepts, beam dynamics optimizations, and comprehensive simulation results for the SIBAF RFQ.
