Simulations of the impact of small details on the magnetic fileld distribution for the compact superconducting cyclotron SC200 commissioning

Modern packages for the design and simulation of cyclotron magnet systems, such as Tosca, CST Studio, Comsol, etc., combined with recent hardware of high performance, allow us to simulate and estimate even a subtle impact on the magnetic field distribution caused by small details and other systems of the accelerator. Such reckoning provides the data to perform and simulate the refilnement of the magnet called the ‘shimming’. That means a signifilcant part of the commissioning stage could be done in ‘virtual reality’. This could substantially decrease the duration of the shimming procedure of the real magnet and the amount of the material wasted on it, eventually this results in a fileld of high-precision which could be compared to real one
