Description
The Rare isotope Accelerator complex for ON-line experiments (RAON) is the first Radioactive Isotope (RI) beam facility in Korea. After the commissioning of the Super-Conducting Linac (SCL3) and the first commissioning experiments carried out in summer 2024, 2025 was marked for the first spectroscopic campaign at RAON, with stable and unstable beams. For this purpose, a large amount of effort was devoted at the Center for Exotic Nuclear Studies (CENS) to develop nuclear detection instruments especially intended for experiments with direct reactions in inverse kinematics: these include ASGARD array of HPGe detectors and STARK Jr silicon barrel array that were the major workhorses of the aforementioned experimental campaign.
This contribution will report on the first spectroscopic study using direct reactions performed at RAON, discussing the physics motivation of these studies, the detailed experimental setup: its current status and the achieved performance, including in-beam commissioning results; and the preliminary outcome of this work. Ongoing development efforts and future experimental plans will also be discussed.
