Beam dynamics simulations at the high energy accelerator section in the RAON accelerator

Abstract

The RAON accelerator is a facility that can generate and accelerate various kinds of ion beams from proton to uranium for a variety of science programs like nuclear sciences, bio-medical sciences, neutron physics, and so on. For efficient beam acceleration, there are low energy and high energy superconducting accelerator sections with different kinds of superconducting cavities which have different optimum betas and RF frequencies in the RAON accelerator. At the low energy superconducting accelerator section, the installation of the accelerator devices and the initial beam commissioning were successfully completed in 2023. Currently, the development of the superconducting cavities in the high-energy superconducting accelerator section is in progress. Here, we will present the recent simulation results of the beam dynamics for the high energy superconducting accelerator section and describe the correction of the distorted beam orbits induced by machine errors as varying the number and location of steering magnets.
