Verification of DECY-13 cyclotron magnet design using cyclotron particle tracking codes

Abstract In order to increase a capacity building of an accelerator development, Center for Accelerator Science and Technology (CAST) - BATAN Yogyakarta, is developing DECY-13 Cyclotron for Positron Emission Tomography (PET) radioisotope production. One of the main components of the cyclotron, a magnet has been designed based on equilibrium orbits analysis of each increase in energy. To assure the designed magnet can guide a particle up to 13 MeV, a particle tracking is important to be carried out using simulation codes that have been benchmarked. Here, the designed magnetic field data and electric field data of the Dee were used in particle tracking simulation. The particle tracking results show that particles in the pass acceptance range can pass the central region and be accelerated up to 13 MeV. These results are consistent with the previous result of our particle tracking code. The range of phase acceptance of accelerated particle is around 110 degrees and the maximum initial axial excursion of the accelerated particles is + 1.5 mm. These results verify that the designed magnet can guide particles up to 13 MeV.
