Description
The Rare Isotope Accelerator complex for ON-line experiments (RAON) at the Institute for Rare Isotope Science (IRIS) is the first heavy-ion accelerator complex in Korea, built to advance rare-isotope beam science.Its main objectives include the discovery of new isotopes and elements using various radioactive-isotope (RI) beams,followed by precision studies to constrain nuclear-structure models and astrophysical processes.To support these goals, a high-power Isotope Separator On-Line (ISOL) facility is being developed to deliver RI beams as primary drivers for experiments.
The ISOL system consists of a proton cyclotron, target and ion-source stations, a radio-frequency quadrupole cooler and buncher (RFQCB), and an electron beam ion source (EBIS), all connected by dedicated transport beamlines. Design work and offline commissioning have been completed,and the first production, extraction, and transport of RI beams have been successfully demonstrated.
Ongoing developments focus on enhancing beam intensity and isotopic variety.A high-beam-intensity capacity target container is being tested to improve in-target production and release.In parallel, laser and Forced Electron Beam Induced Arc Discharge (FEBIAD) ion sources are being optimized offline and integrated online to broaden efficiency, selectivity, and chemical coverage.Beam optics from the target to the cooler and the charge breeder are also being refined to improve transmission and purity.
The presentation will summarize the current status of the ISOL facility, including optics performance and initial online results,and will outline near-term upgrades to targets and ion sources, aimed at maximizing the scientific potential of RAON in nuclear physics.
