  This paper presents the latest results of high current proton and deuteron beam production at SMIS 37 at the Institute of Applied Physics. In this experimental setup the plasma is created by 37.5 GHz gyrotron radiation with power up to 100 kW in a simple mirror trap. High microwave power and frequency allow sustaining higher density hydrogen plasma in comparison to conventional ECRIS's or microwave sources. The low ion temperature, on the order of a few eV, is beneficial to produce proton beams with low emittance. Latest experiments with hydrogen and deuterium show possibility of beam formation with currents up to 550 mA at high voltages below 45 kV with normalized rms emittance lower than 0.2 pi*mm*mrad. Such beams have a high potential for application in future accelerator research. Also in frames of the present paper it is suggested to use such an ion source in a scheme of D-D neutron generator. Such ion source can produce deuteron ion beams with current density up to 700-800 mA/cm2. Generation of the neutron flux with density at the level of 7-8*1010 s−1cm-2 could be obtained in case of TiD2 target bombardment with deuteron beam accelerated to 100 keV.

  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.
