Magnet design for the 10MeV AVF cyclotron accelerator

In this paper, an azimuthally varying field (AVF) magnet is designed to produce a 10 MeV proton beam. In order to design and analyze the magnet three-dimensionally, we use the CST program. Also, field mapping results have been obtained by using the CST program and the MATLAB program to validate the precision of the design. In addition, an iterative process is conducted for magnet shimming. The precision of this design is ensured by using the optimization part of CST to optimize parameters like the number of mesh cells, the boundary dimension, etc.
