The present efforts in upgrading the cyclotron are directed towards an increase of beam power up to 10 kW for ions with mass number A < 40 and energies between 15 and 70 AMeV by means of increase of beam intensity. Moreover, a beam energy resolution of 0.1% is requested by the NUMEN project at INFN-LNS. We plan to achieve high beam power by increasing the efficiency of the injection and extraction processes. The current extraction efficiency is lower than 60%. We expect to increase it to a value close to 100% by extracting the specific ion beams by stripping and no longer by electrostatic deflectors. A spiral inflector is used to bent onto the median plane the ion beams produced by the two ECR ion sources. Including the effect of a drift buncher placed in the axial injection line, the current injection efficiency is about 15%. The study of an upgraded CS central region is ongoing at INFN-LNS. First results of simulation study aimed to increase the injection efficiency are presented.
