  The number of PET facility is rapidly increasing worldwide. To get PET image, circular accelerator such as cyclotron is needed. Compact 9 MeV H-cyclotron, which has a diameter of 1.25m is being designed at Sungkyunkwan University starting from July 2010 for getting F-18. It is expected to be constructed by next year. In this paper, RF system of 9 MeV cyclotron including design processes and detail analysis of result is reported. RF system mainly describes RF cavity design.

Low energy compact cyclotrons for Positron emission tomography (PET) are needed for the production of radio-isotope. In the magnet design for those cyclotrons, single particle tracking simulation after the design is important to check the quality of designed magnetic field of the magnet. The study of single particle tracking simulation for cyclotron magnet is shown in this paper. Maximum beam energy of example cyclotron is 9 MeV for proton and pseudo accelerating gap is adapted for the simulation. 3D CAD program CATIA P3 V5 R18 is used for design the magnet and pseudo accelerating gap. All magnetic and electric field calculations had been performed by OPERA-3D TOSCA and the own-made program OPTICY is used for other calculations - phase slip, radial and axial tune.

Cyclotron electromagnet for RI production which is used for PET scanning has been designed. Designed pancake-shape electromagnet is an advanced type of KIRAMS-13's electromagnet which has the H-type electromagnet. The AVF structure with hill and valley was used for getting strong axial focusing and producing the energy of proton beam up to 13MeV with a thin stripper foil. To design and analyse the magnet, 3D CAD (CATIA V5)and TOSCA (OPERA-3D)were used, respectively. To reduce the calculation time, routine files were developed which can generate model, mesh and field map automatically in TOSCA modeller and post processor. The beam dynamics program OPTICY is used for calculation of the tunes.
KIRAMS-13* is the cyclotron had been manufactured by KIRAMS.
KIRAMS is short for Korea Institutes of Radiological and Medical Science.
