Abstract
The RAON accelerator has been constructed for various
science programs with stable ions and rare isotopes since
2011. After the installation of the injector section was completed
in 2020, the low-energy superconducting accelerator (SCL3) section
was also installed consecutively until 2022, and the beam
commissioning using an argon beam is in progress from the injector
section to the SCL3 section. For successful beam commissioning,
various beam dynamics studies have been carried out, and the
research of the orbit correction has been also conducted to
determine the location and the number of steering magnets and BPMs
for safe and efficient beam operation. In the SCL3 section, the
orbit correction simulation was carried out as varying the number of
steering magnets for the consideration of the correction of
distorted beam orbit and the economic benefits, and then the beam
test was carried out based on the simulation results during the beam
commissioning. Here we will present the results of simulations and
experiments for the orbit correction at the SCL3 section in the RAON
accelerator.
