  • Computer modeling of charge particle beam extraction and transport 
    Litovko, I.V.; Oks, E.M. (Вопросы атомной науки и техники, 2007)
    The computer simulation of the extraction of high current charge particle beam from a plasma source and its transport has been used for investigation of the beam quality and its dependence from plasma parameters. The ...
  • Emerging trends in wall-free Hall thrusters development 
    Litovko, I.V.; Bazhenov, V.Yu.; Goncharov, A.A.; Dobrovolsky, A.N.; Naiko, I.V. (Вопросы атомной науки и техники, 2021)
    2D-hybrid model was created for the proposed new type accelerator with a virtual cathode which allows to avoid sputtering of the cathode surface and to preserve the dynamics of accelerated ions. In the framework of the ...
  • Evaporation of micro-droplets in cathode arc plasma coating under formed electron beam 
    Goncharov, A.A.; Maslov, V.I.; Litovko, I.V.; Ryabtsev, A. (Problems of Atomic Science and Technology, 2022)
    Evaporation of micro-droplets in an arc plasma flow under the action of a self-consistency electron beam and the condition of direct heating of micro-droplets by fast electrons are considered. It is shown that the plasma ...
  • Ion sources optimization for high energy ion implantation by computer simulation 
    Litovko, I.V.; Gushenets, V.I. (Вопросы атомной науки и техники, 2008)
    Results of the computer simulation for ion sources optimization used for ion implantations have been done. The highly stripped ion source has been designed to provide high current beams of multiply charged P and B ions for ...
  • Last results of novel plasmaoptical devices investigation 
    Goncharov, A.A.; Dobrovolsky, A.M.; Bazhenov, V.Yu.; Litovko, I.V.; Naiko, I.V.; Naiko, L.V.; Kostin, E.G.; Protsenko, I.M. (Вопросы атомной науки и техники, 2018)
    The combined system composed of the vacuum arc evaporator and plasmaoptical system with plasma lens (PL) geometry are presented and studied. The plasmadynamical characteristics of high density low energy plasma flow propagating ...
  • 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 ...
  • Temperature dynamics of the microdroplet fraction of metal plasma in plasma-optical devices with fast electrons 
    Goncharov, A.A.; Litovko, I.V.; Ryabtsev, A.V. (Problems of Atomic Science and Technology, 2023)
    The computer simulation of a plasma filter with fast electrons shows that the main source of droplet heating is thermal electrons, while the role of fast electrons is reduced mainly to transferring energy to slow electrons. ...
  • The development of the positive space charge plasma lens for manipulating high current beams of negatively charged particles 
    Dobrovolskiy, A.N.; Dunets, S.P.; Evsyukov, A.N.; Goncharov, A.A.; Gushenets, V.I.; Litovko, I.V.; Oks, E.M. (Вопросы атомной науки и техники, 2011)
    We describe the development of the plasma lens with dynamic positive space charge for manipulating and focusing intense beams of negative charge particles. Floating potential spatial distributions in lens with modified ...
