Description
RAON is a heavy ion accelerator complex in Daejeon, Republic of Korea. Its beam commissioning of low energy superconducting linear accelerator (SCL3) have been finished by Institute for Rare Isotope Science (IRIS) in Institute of Basic Science (IBS). The purpose of this accelerator is the generation of rare isotope by ISOL (Isotope Separation On-Line) and its acceleration for the nuclear physics experiment. SCL3 consists of 22 quarter wave resonator (QWR) type cavities and 102 half wave resonator (HWR) type cavities and their operating RF frequencies are 81.25 MHz and 162.5 MHz. Every cavity can be controlled independently for the flexibility to accelerate the various A/q ions. The development, evaluation and installation of the digital LLRF based on the FPGA technology have been finished in 2022. The self-excited loop (SEL) and the generator-driven-resonator (GDR) algorithm are implemented and they are being used for the accelerator operation. In this presentation the status of RAON LLRF and some preliminary research result related to its upgrade will be described.
