Along the last twentyfive years, INFN-LNS has gained a relevant role in R&D of plasma-based ion sources. The laboratory is currently involved in the Proton Source and Low Energy Beam Transport (LEBT) line prototype construction for the European Spallation Source. ESS – based on a 2.0 GeV, 62.5 mA proton accelerator for neutron production – will be a fundamental instrument for research and application. The proton source is required to produce at least 90 mA beam (as total drain current) at 0.25 π.mm.mrad emittance, 2.86 ms pulse duration, 14 Hz repetition rate. We will illustrate the advanced design of the machine, including the innovations in plasma heating schemes, the final layout of the LEBT – based on detailed beam transport studies, a new vacuum scheme and the final chopper strategy – and the first steps of the devices installation at the INFN-LNS test-bench site.
