Simulations of beam-based alignment at RAON SCL2

The RAON accelerator has low-energy and high-energy superconducting linear accelerator sections to achieve 200 MeV/u uranium beam energy. In these sections, the machine imperfections and the beam instabilities can induce unexpected beam loss, and it can lead to significant damage of accelerator devices. To prevent these effects, various beam dynamics studies have been carried out, and the simulations for the beam-based alignment to prevent the sudden beam loss have been also carried out. Here we will present the results of beam-based alignment simulations at the high energy accelerator section (SCL2) of the RAON accelerator.
