  CNAO is the Italian National Center of Oncological Hadrontherapy in Pavia. Proton beams are accelerated in the synchrotron and extracted in the energy range 60 to 250 MeV/u and carbon ion beams in the energy range 120 to 400 MeV/u. Trapping at the injection energy of 7 MeV/u and acceleration up to the extraction energy are done by an RF cavity which covers the needed wide range of frequency (0.4 to 3 MHz) and voltage (25 V to 5 kV) thanks to the use of a Vitrovac amorphous alloy. RF Gymnastics, including phase jumps to increase the momentum spread and empty bucket channelling, is requested and has been performed. A description of the hardware characteristics of the CNAO RF system and of its performance in terms of dynamic and static behaviour are reported in this paper.
