Description

The RAON linear accelerator consists of a front-end injector and a superconducting linear accelerator (SCL3). The injector includes a 14.5 GHz Electron Cyclotron Resonance (ECR) ion source and a Radio Frequency Quadrupole (RFQ). The ECR ion source can generate a wide range of ion beams, from protons to uranium, with an energy of 10 keV/u. The RFQ accelerates these ion beams up to 500 keV/u. The superconducting linear accelerator, SCL3, is equipped with Quarter Wave Resonators (QWRs) and Half Wave Resonators (HWRs), enabling uranium beams to reach energies of up to 18.5 MeV/u. Beam commissioning of the injector began in August 2021, with tests conducted using argon, neon, oxygen, helium, and proton beams. Commissioning of SCL3 started in October 2022, utilizing argon beams generated by the ECR ion source. This work presents the current status of RAON linear accelerator beam commissioning from a beam dynamics perspective.
