Abstract

KHIMA, a research project to construct a carbon radio-therapy facility in Korea, has been developing a superconducting cyclotron named KIRAMS-430 as a carbon(¹²C⁶⁺) particle accelerator. Due to the fixed beam energy of the cyclotron, an energy selection system (ESS) is required for treatment of tumors located at various depths in the human body. In the present paper, two design stages of the ESS are discussed. First, the beam tracks behind the degrader block and the statistical twiss parameters for the entire energy range were calculated by using the GEANT4 simulation toolkit. Analysis of the beam transmission and the contamination ratios were performed. In the second stage, the beam optics was designed to support the same phase profile at the end regardless of the variations in all of input twiss parameters and the emittance.
