Modeling and forming the magnetic field of the heavy ion cyclotron

The heavy ion cyclotron was designed and constructed in the Dzhelepov Laboratory of Nuclear Problems, Joint Institute for Nuclear Research. The magnetic field of this cyclotron is formed in the compact magnet with the pole diameter 1.6 m by means of four pairs of sector shims installed symmetrically up and down. The gaps are 100 mm, and 40 mm between the poles and shims, respectively. The proper dependence of the isochronous magnetic field on the radius is created, basically, by increasing the angular extension of sector shims inside the range α = 30 degree...41.8 degree. Power consumption of an electromagnet is 25 kW
