	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.

	The ion sources, required by medical applications, must provide intense ion beams, with high reproducibility, stability and brightness. AISHa (Advanced Ion Source for Hadrontherapy) is a compact ECRIS whose hybrid magnetic system consists of a permanent Halbach-type hexapole magnet and a set of independently energized superconducting coils. These will be enclosed in a compact cryostat with two cryocoolers to operate without LHe. The microwave injection system has been designed for maximizing the beam quality through a fine frequency tuning within the 17.3-18.4 GHz band which is possible by using an innovative variable frequency klystron. The introduction of an integrated oven will allow the production of metal ions beams with relatively high intensity. “Accel-decel” extraction system will be used. The LEBT line will consist of a solenoid and a 90° dipole for ions selection. Two diagnostic boxes, made of Faraday cups, beam wires and slits, will allow the investigation of the beam composition and its properties. Moreover, a system of scintillating screens and CCD cameras, placed after the solenoid will allow the investigation of the Frequency Tuning Effect on the source performances.
