SNOP ± BEAM DYNAMICS ANALYSIS CODE FOR COMPACT CYCLOTRONS

The SNOP program complex intended for particle dynamics simulations in a compact cyclotron from the injection line to the extraction system is described. The main features of the SNOP are usage of 3D electric and magnetic field maps, beam space charge effect calculation, and analysis of the beam losses on the structure elements of the facility under consideration. The optimal usage of modern computer capabilities and graphic libraries for visualization is a key issue in the SNOP development. The beam dynamics modeling results for various cyclotrons are presented.
