High-current RFQ Design Study on RAON

Rare isotope Accelerator Of Newness (RAON) heavy ion accelerator has been designed as a facility for a rare isotepe accelerator of the Rare Isotope Science Project (RISP). RAON provides 400 kW CW heavy ion beams from proton to uranium to support researches in various science fields. The RAON system consists of a few ECR ion source, low energy beam transport systems (LEBTs), CW radio frequency quadrupole (RFQ) accelerators, a medium energy beam transport and superconducting linac. We present the design study of the RFQ accelerator from 30 keV/u to 1.5 MeV/u of deuteron beam with meeting a requirement of over 15 mA beam at the target. We optimized the normal conducting CW RFQ accelerator that has a high transmission and a low longitudinal emittance. In this paper, we will present the design result of RFQ beam dynamics studies and its 2D and 3D EM analysis.
