| Abstract |
The 18MeV cyclotron magnet was designed for medical application at Amirkabir University of Technology. In magnet simulation all other subsystems should be considered, because all of them are related with magnet. Designed magnet with 4 hills and valleys has AVF structure. The TOSCA(Opera-3D)code was used for simulation and analysis. Designing process summarize in tow steps: At first all theoretical calculation of magnetic field according to radius were done and it's curve which is named theoretical curve was plotted. In next step simulation in TOSCA code was done with a simple model of magnet and optimization process began until when the curve of the simulation result coincided with the theoretical curve. The result showed that at most radius, the isochronous magnetic field difference between simulated values and calculation is less than 10 Gauss, so designed magnet is optimized. Also the particle trajectories were illustrated. According to the results, work points of the cyclotron are far from the resonances region. With considering reliable mesh the accuracy of simulation result is sufficient high.
