Description
RAON, Korea’s heavy-ion accelerator facility, completed the construction of its low-energy linac section in 2022 and is currently providing beam services for user experiments. While the existing facility supports a broad range of research in rare isotope science, nuclear physics, nuclear astrophysics, and radiation applications, extending the accelerator to higher energies is essential for exploring nuclear phenomena under more extreme conditions and enhancing the facility’s international competitiveness. To support the future construction of the RAON high-energy linac section, a preliminary R&D program is underway to develop superconducting accelerator technologies that have not yet been established in the IBS. As part of this effort, prototype superconducting accelerator modules for the high-energy Linac sections are being designed, fabricated, and tested. Key performance parameters under investigation include accelerating gradient, operational stability, resonant frequency characteristics, phase control, thermal stability, and overall module performance. The completed facility is expected to become a globally unique research infrastructure capable of simultaneously supporting both the Isotope Separation On-Line (ISOL) and In-flight Fragmentation (IF) rare-isotope production methods. This presentation reports the current progress of the technology development program and outlines the roadmap toward the realization of the RAON high-energy linac accelerator section.
