  • Development of negative ion source with combined discharge 
    Goretskii, V.P.; Dobrovolskiy, A.M. (Вопросы атомной науки и техники, 2015)
    The results of investigation of emission productivity of negative particles source with combined discharge are presented. A cylindrical beam of negative hydrogen ions with density about 5 A/cm² on source emission aperture ...
  • Gas magnetron deposition of structured TiO₂ nanofilms 
    Dobrovolskiy, A.M.; Goncharov, A.A.; Kostin, E.G.; Frolova, E.K. (Вопросы атомной науки и техники, 2013)
    The paper describes the peculiarities of deposition nano-sized titanium dioxide coatings in the cylindrical inverted gas magnetron. It is shown the influence of the main parameters magnetron sputtering, like as working gas ...
  • Investigation of antimicrobial activity and morphological properties of metal coated textile surfaces

    The results of investigation antimicrobial and surface properties of the textiles metal coated by means of magnetron or the cleaning-deposition system, which is based on sequentially arranged DC anode layer accelerator and ...
  • Peculiarities of hydrogen negative ion beams extraction from axially symmetric source with crossed fields 
    Goretskii, V.P.; Dobrovolskiy, A.M. (Вопросы атомной науки и техники, 2015)
    A comparison of emission features of axially symmetric H⁻ ion source with magnetron discharge and H⁻ source which incorporates additional hollow cathode discharge in series with main one is presented. It is shown that in ...
  • Plasma treatment of titanium dioxide film for black TiO₂ 
    Frolova, E.K.; Khomych, V.O.; Kravchuk, R.M.; Kolomys, O.F.; Gudenko, Yu.M.; Pylypchuk, O.S.; Styopkin, V.I.; Dobrovolskiy, A.M. (Problems of Atomic Science and Technology, 2023)
    The results of the treatment of TiO₂ film in volume discharge with an Ar/H₂ mixture are presented. The treated film demonstrates the changes in transparency and conductivity. Raman spectra show no changes in the phase state ...
  • Present status of the positive space charge lense for focusing intense negative charged particle beams 
    Goncharov, A.A.; Dobrovolskiy, A.M.; Dunets, S.M.; Litovko, I.V.; Gushenets, V.I.; Oks, E.M.; Bugaev, A.S. (Вопросы атомной науки и техники, 2012)
    We describe the new experimental and simulation results of wide-aperture (6 cm) non-relativistic (up to 18 keV) intense (up to 400 mA) electron beam focusing by the positive-space-charge plasma lens. Recently we proposed ...
  • Two stage plasma source for large scale beam generation 
    Bazhenov, V.Yu.; Dobrovolskiy, A.M.; Tsiolko, V.V.; Piun, V.M. (Problems of Atomic Science and Technology, 2023)
    The operation of a cylindrical plasma accelerator with an anode layer in the mode of ion space charge accumulation and the use of an ion flow accelerated by a space charge is investigated. In particular, the presence of ...
