Description
RAON (Rare isotope Accelerator complex for ON-line experiments) is a heavy-ion accelerator facility constructed through the Rare Isotope Science Project (RISP) to support rare-isotope science in Korea. Since 2024, RAON has delivered stable-isotope beams, including Ar, O, and Ne, using a 14.5 GHz Electron Cyclotron Resonance Ion Source (ECRIS) for user experiments. Recently, rare-isotope beam delivery from the Isotope Separation On-Line (ISOL) system has begun, increasing the need for reliable and flexible ion-source operation for various beam species. To improve beam availability and operational flexibility, RAON plans to operate multiple ion sources: the existing 14.5 GHz ECRIS, a 28 GHz ECRIS under development, and an additional 14.5 GHz ECRIS. The new source will be used for preliminary beam tests with stable isotopes, optimization of operating conditions, and backup operation during maintenance of the primary source, thereby supporting more reliable accelerator operation. This paper presents the conceptual design and current development status of the additional 14.5 GHz ECRIS. Based on operational experience with the existing source, the required performance, major components, and planned operation scenarios are described.
