Description

RAON (Rare Isotope Accelerator for ON-line experiment) is a heavy-ion accelerator developed through the Rare Isotope Science Project (RISP) from 2011 to 2023, and has been providing beams to users since 2024. Currently, stable isotope beams such as argon, oxygen, neon, and other ion species are supplied using an Electron Cyclotron Resonance Ion Source (ECRIS). In addition, radioactive isotope (RI) beams have recently been delivered to users via the Isotope Separator On-Line (ISOL) system.

To ensure stable beam operation, RAON aims to operate three ion sources. At present, a 14.5 GHz ECRIS is in operation, while a 28 GHz ECRIS is under development. Furthermore, an additional 14.5 GHz ECRIS is being developed to enable pre-testing of various beams and to enhance the operational flexibility of the accelerator.

This paper presents the conceptual design and current development status of the additional 14.5 GHz ECRIS as a spare ion source, and discusses its potential applications.
