Abstract
The RAON accelerator is currently under construction to generate and accelerate stable ions and rare isotopes for various kinds of scientific programs, and it will be completed by the end of 2021. In the RAON accelerator, the beams generated by using ion sources such as electron cyclotron resonance ion source and isotope separation on-line can be used in high energy experiments such as a beam irradiation system and a muon spin rotation/relaxation/resonance system after having been accelerated by low energy and high energy superconducting linacs. After the high energy superconducting linac, the beam passes through the high energy beamline and then collides with the target. In 2015, the lattices of the high energy beamlines were designed achromatically to minimize the emittance growth. However, as the specification of magnets in the beamline was changed after first lattice design, a beam dynamics simulation has been performed newly, and beam loss studies have also been conducted. Here, we will present the simulation results for the beam dynamics and describe the beam loss studies performed on the high energy beamlines of the RAON accelerator.
