Up to now the maximum beam power has been limited to 100 W due to the beam dissipation in the electrostatic deflectors. To fulfill the users request, aiming to study rare processes in Nuclear Physics, the beam power has been planned to be increased up to 2-10 kW for ions with mass lower than 40 a.m.u., to be extracted by stripping. This development will maintain the present performance of the machine, i.e. the existing extraction mode will be maintained for all the ion species allowed by the operating diagram. To achieve this goal, a significant refurbishing operation of the cyclotron is needed, including a new cryostat with new superconducting coils, a new extraction channel with a large vertical gap, additional penetrations to host new magnetic channels and new compensation bars. Moreover the vacuum in the acceleration chamber is planned to be improved by replacing the liners and the trim coils. A general description of the refurbishing project will be presented.
