This facility creates and heats up the plasma by 37.5 GHz gyrotron radiation with power up to 100 kW in a simple mirror trap meeting the ECR condition. High microwave power and frequency allow sustaining plasma of significantly higher density (Ne up to 2·10¹³ cm⁻³) in comparison to conventional ECRISes or other microwave ion sources. The low ion temperature, on the order of a few eV, is beneficial to produce ion beams with low emittance. Latest experiments at SMIS 37 were performed using a single-aperture two-electrode extraction system. Various diameters of plasma electrode apertures i.e. 5 mm, 7 mm, 10 mm, were tested yielding proton and deuteron beams with currents up to 500 mA with RMS emittance lower than 0.2 π·mm·mrad at extraction voltages up to 45 kV. The maximum beam current density was measured to be 800 mA/cm². A possibility of further improvement through the development of an advanced extraction system is discussed.
