  The Centro Nazionale di Adroterapia Oncologica (National Center for Oncological Hadrontherapy, CNAO) is the Italian center for deep hadrontherapy. It will deliver treatments with active scanning both with proton and carbon ion beams. At CNAO two ECR sources of the Supernanogan type (built by the Pantechnik company according to specifications set by INFN) are installed and run continuously and in parallel, to allow the fast change of the particle species. The two sources are identical and can provide both particle species after a simple switch from one gas to the other, which allows as well to run the facility, in emergency, with only one source. Each source is equipped with a dedicated beam line including a spectrometer and beam diagnostics. Optimisation of beam emittance and intensity is of primary importance to obtain the necessary current at the RFQ-LINAC and then at injection. The preliminary tests have shown the complete fulfillment of the specifications in terms of beam current and emittance and the final tests are ongoing. A description of the source design and performance will be presented.
