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.

Development trend of the modern ECR ion sources is connected with the continued increase of the heating radiation frequency and, as a consequence, increase of the magnetic field value. In this case the construction of the MHD stable non-axial symmetric magnetic systems becomes rather complicated. Thus, the search of axial symmetric magnetic systems with depressed transversal losses caused by MHD instabilities is in a great demand. In this report some of the possible versions of such magnetic systems are presented: cusp magnetic trap, system with magnetic divertor and the mirror trap with the differential rotation layer in plasmas. Perspectives of using these systems in the ECR ion sources according to the results of experimental investigations on SMIS 37 setup in Nizhny Novgorod are discussed.

It is proposed in this paper to use discharge plasma supported by terahertz radiation as a source of EUV light for high-resolution lithography. In this report we discuss the experimental investigation of two types of EUV sources based on discharge, supported by powerful gyrotron radiation. Following investigation results are described: -a series of experiments that demonstrate the generation of EUV light from the vacuum-arc discharge plasma in tin vapor in the magnetic trap heated by gyrotron radiation with a frequency of 75 GHz under electron cyclotron resonance (ECR) conditions; -a numerical modeling of the plasma emissivity in the EUV range, depending on the parameters of the heating radiation is performed; -experimental studies of EUV emission from plasma discharge sustained by strong terahertz powerful radiation in inhomogeneous gas flows are started.
