Current Design Status of High Energy Beam Transfer Line for KHIMA Project

The Korea heavy ion medical accelerator (KHIMA) project is developing and constructing the heavy ion medical accelerator for the first time in Korea since 2010. This paper describes the status of high energy beam transfer line (HEBT), which connects the superconducting cyclotron to the treatment rooms. The HEBT provides a patient with 145–430 MeV/u carbon (12C6+) beam to cure cancer. The HEBT is consisted of 6 beam lines (4 horizontal, 1 vertical and 1 oblique). The size of the design HEBT is 41 m in length, 11 m in width and 17 m in height. Total number of magnets is 53 for focusing magnets and 22 for bending magnets. In the description, the current design status of the HEBT is described.
