Design of KIRAMS-13 RF system for regional cyclotron center

At the Korea Institute of Radiological and Medical Sciences (KIRAMS), the design study of a 13 MeV cyclotron (KIRAMS-13) for Positron Emission Tomography (PET) had been developed in 2001. The KIRAMS-13 has been improved for regional cyclotron center. The magnet design was changed to reduce electric power consumption. We shorted the length of a pole gap by 20 mm and increased number of turns from 18x8 to 16x19. So, electric power consumption was reduced about 67%. However, main RF parameters were not changed to reduce production cost and time. So, we had to consider the RF system design as a result of changing the magnet design. For satisfying these preconditions, we only redesigned the linear and the central region of KIRAMS-13. In this paper, we describe the RF simulation and experimental results focused on the change of structures and the progress being made in production work for regional cyclotron center. (author)
