   Cyclotrons are frequently used for medical applications together with physics research. In such a case, machine design becomes complicated because the cyclotron must produce beams of different particles at different energies. The beam-extraction is a special problem for these machines. The paper presents a study of the beam extraction from the multi-purpose isochronous cyclotron DC-72 that is being designed and constructed for the Cyclotron Centre of the Slovak Republic (CC SR). Charge-exchange extraction has been studied and optimized. It is demonstrated that extraction of different ions at different energies through a common extraction channel is feasible.
