Air core superconducting cyclotrons

This paper summarizes the major conclusions of the design study of superconducting booster cyclotrons. The goal of the study was to provide preliminary design of air core superconducting cyclotron, which should be able to accelerate not only heavy ions, but also p,d and He particles as close as possible to the energies of bending limit K Z2/A. The considerations demonstrate the encouraging possibilities of air core superconducting cyclotrons in matching the requirements for multipurpose cyclotron even at large K number. The guidelines in designing the main coil and active flutter configurations are given together with solutions envisaged for the problems arise from the presence of limiting phenomena. The great emphasis in design considerations was placed on the cost savings, that are, in this cyclotron concept possible
