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. An FPGA-based digital LLRF system has been in operation in this section since 2022. Because this system uses an LVDS interface to drive the DAC, a timing scan is required to determine the optimal interface timing and ensure reliable data transfer. An algorithm for automatically scanning the interface timing and applying the optimal timing parameters has recently been developed and tested. This presentation describes the algorithm and presents preliminary test results.
