AB - At the Istituto Nazionale di Fisica Nucleare ' Laboratori Nazionali del Sud (INFN-LNS) the beam commissioning of the high intensity Proton Source (PS-ESS) and the Low Energy Beam Transport (LEBT) line for the European Spallation Source (ESS) has been completed. The official project schedule was satisfied and the source has been installed in the ESS accelerator tunnel on January 2018. Due to the high flexibility of the magnetic system, and to the innovative approach developed for the commissioning, we were able to test a huge amount of configurations (more than 400'000). The optimum source configuration that satisfy all requirements at the same time has been identified. The source is able to produce a stable total current between 40 and 125 mA (90 mA requested) through an 8 mm extraction aperture, with a proton fraction of up to 87%. At the end of the LEBT the beam characteristics fully satisfy the ESS requirements: more than 70 mA of proton beam with 99% normalized beam emittance of 2.25 '.mm.mrad have been transported with intra pulse current fluctuation below ±1.5% and long term current fluctuation below ±3%. Results and used strategy are shown in details.
