  SPIRAL1 Upgrade hardware is now almost completed. The FEBIAD 1+ source has been tested for the production of new radioactive isotopes, PHOENIX Charge Breeder (CB) is in place reproducing nearly the charge breeding efficiencies measured at LPSC lab and the infrastructure is operational to welcome such new multifaceted devices. The commissioning phase started in the second semester of 2017. It has consisted of a stepwise process to test the upgrade of the SPIRAL1 facility from simple validation (operation of CB as a stand-alone source) up to the production of the first 1+/n+ Radioactive Ion Beam (RIB) with the 37K9+. This contribution will summarize the different steps completed successfully and especially the measurements done to validate each of the commissioning stages. These include e.g. ionization efficiencies for CB; beam line optics for 1+/n+ and charge breeding efficiencies. The remaining effort required to ensure the reliability of the complete system for routine RIB operation is also presented. A section will be dedicated to a new feature of SPIRAL1 facility: combination of CB and CIME leads to deliver stable beams with energies never done until now.

  In the framework of the SPIRAL1 facility, the R \& D of charge breeding technique is of primary interest for optimizing the yields of radioactive ion beams (RIBs). This technique involves the transformation of mono-charged ion beams into multi-charged ion beams by operating an Electron Cyclotron Resonance (ECR) charge breeder (CB). During the SPIRAL1 commissioning, experimental studies have been performed in order to understand the transport of the beam through the CB with and without ECR plasma. Numerical simulations including ion optics and some ECR plasma features have been developed to evaluate ion losses during the ion transport through the CB with and without a simplified model of the ECR plasma.
