TL;DR: The Indiana University 200 MeV Isochronous Cyclotron as mentioned in this paper is a separated sector (N = 4) machine whose design goals include the acceleration of both protons and heavy ions over a variable energy range up to a maximum energy of approximately 220 Z2/A MeV.
Abstract: The Indiana University 200 MeV Isochronous Cyclotron is a separated sector (N = 4) machine whose design goals include the acceleration of both protons and heavy ions over a variable energy range up to a maximum energy of approximately 220 Z2/A MeV. The large range in energy and particle mass requires that the radial profile of the magnetic fields be adjustable to match the relativistic mass increase of the accelerated particle. For the acceleration of protons to 200 MeV for example, an increase in the field from injection to extraction radius of about 22% is needed, whereas for heavier ions the field profile must rise approximately 2%.
