Considerable efforts have been drawn to adapt heavy ion beams imitation experiments for investigation of radiation stability of materials in nuclear industry, mainly structural materials - steels. Formation of defect structure in the steel using the neutron flow from the nuclear reactors is fraught with many difficulties such as a long-term session of exposure and induced radioactivity in the irradiated samples. Whereas, heavy ions could provide a versatile tool to induce a precise damage in material under controlled condition. The LEGnaro ECR Ion Source (LEGIS) installed at the high voltage (up to 300 kV) platform enables the unique possibility for wide range program of reactor steels investigation by heavy ion beams. The sample irradiation up to hundreds of dpa (displacement-per-atom) in less than an operation day can be provided by beams of different ions ranging from hydrogen to the iron with different energy. The investigation program and details of experimental facility are presented and discussed.

At INFN-LNS, ECRIS development during the ‘90s boosted the K-800 Cyclotron performances: SERSE and CAESAR have then well supported Nuclear Physics research. For the new needs of the laboratory, further improvements are required and here described. Activities recently started aimed to the production of multicharged ion beams and to the production of intense light ion beams. Technological developments led the AISHa source design, now under construction, in order to adapt a high performance ECR ion source to hospital facilities needing multiply charged ion production with high reliability and brightness, easy operations and maintenance. The realization of the 75kV-70mA proton source, called PS-ESS, and of its LEBT for the forthcoming European Spallation Source in Sweden is one of the major engagements of the INFN-LNS. Other activities are ongoing on high charge state and high intensity beam production: a major update is going to be finalized on SERSE cryogenic system; at Vancouver, the VIS source is used for producing multi-mA beams of H²⁺ for a high-current cyclotron; a new flexible plasma trap is under test for fundamental research about innovative plasma heating methods.

One of the Work Packages of the "Enhanced Multi-Ionization of short-Lived Isotopes at EURISOL" NuPNET project focuses on the ECR charge breeding. The LPSC charge breeder is used for experimental studies in order to better understand the fundamental processes involved in the 1+ beam capture by a 14 GHz ECR plasma. Some improvements, like symmetrisation of the magnetic field at the injection side and higher pumping speed, have been carried out on the PHOENIX charge breeder. The impact of these modifications on the efficiencies and charge breeding times are presented. In the same time, the new LPSC 1+ source developments performed in order to ease the efficiency measurements with various elements are presented.
