Abstract A semi-3D method to calculate the median plane magnetic field in a conventional sector-focused cyclotron was developed in order to avoid the need of model magnet studies in the design of the Jyvaskyla K130 cyclotron. The method gives reasonably good results especially at high fields. At low fields where the relative permeability of iron is high the field can be calculated assuming constant magnetic scalar potential on the iron surfaces and solving a three-dimensional Laplace equation. The field calculation methods will be described and the comparison of calculated and measured fields will be given.
