A 14 MeV AVF cyclotron magnet design for PET applications

A foursector 14 MeV azimuthally varying field Htype cyclotron magnet has been designed for positron emission tomography (PET) at Sungkyunkwan University. Compactness, feasibility, and high performance are among the main factors that were considered in the design, which is ultimately intended made for use in hospitals and research institutes. After optimizing the initial parameters using the shimming method, an isochronous magnetic field along the cyclotron radius through Opera3d was investigated. The particle trajectories were also illustrated. The Cyclone equilibrium orbit code program was used to examine the radial and axial betatron oscillations in relation to the cyclotron operating points. In addition, the integrated phase shift was explained and compared to the Korea Institute of Radiological Medical Sciences 13 MeV cyclotron (KIRAMS13). In conclusion, the final shape magnet satisfied the orbital stability requirements. The RF cavity, vacuum pump, and injection system could be employed efficiently, and a reliable agreement was reached between KIRAMS13 and our design characterization.
