  • Dependence of wakefield excitation in plasma by non-resonant sequence of electron bunches on their lengths 
    Bondar, D.S.; Boychenko, A.P.; Maslov, V.I.; Onishchenko, I.N.; Ovsiannikov, R.T. (Вопросы атомной науки и техники, 2021)
    The present paper describes the results of numerical simulation (using 2d3v code LCODE) of the regime, when the wakefield is excited at maximum growth rate in the plasma by a nonresonant sequence of relativistic electron ...
  • Numerical simulation of plateau formation by an electron bunch on the distribution of an accelerating wakefield in a plasma 
    Maslov, V.I.; Ovsiannikov, R.T.; Delerue, N.; Kubytskyi, V.; Levchuk, I.P.; Onishchenko, I.N. (Вопросы атомной науки и техники, 2020)
    Over the past decade the production of multi-gigaelectrons from laser-driven and electron-bunch-driven plasma accelerators has been successfully demonstrated. However, applications require improvements of accelerated bunch ...
  • Plasma lens for electron and positron beams 
    Bondar, D.S.; Maslov, V.I.; Onishchenko, I.N.; Ovsiannikov, R.T. (Вопросы атомной науки и техники, 2021)
    Focusing of both electron and positron bunches in electron-positron collider is necessary. When long electron/positron bunch is injected into the plasma, the focusing force is not uniform but oscillated. It is shown that ...
  • Plateau formation on accelerating wakefield for electron-witness-bunch and on decelerating wakefield for driver-bunches in a plasma 
    Maslov, V.I.; Ovsiannikov, R.T.; Bondar, D.S.; Levchuk, I.P.; Onishchenko, I.N. (Вопросы атомной науки и техники, 2021)
    Plasma wakefield acceleration promises compact sources of high-brightness relativistic electron and positron beams. Applications (particle colliders and free-electron lasers) of plasma wakefield accelerators demand low ...
  • Structures of vortexes near the poles of planets of the solar system 
    Maslov, V.I.; Cassé, M.; Cheremnykh, O.K.; Fomina, A.P.; Grasso, D.; Kholodov, R.I.; Novak, O.P.; Ovsiannikov, R.T. (Problems of Atomic Science and Technology, 2023)
    In the vicinity of the poles of the planets of the solar system, ordered crystals of vortices and intermittency are observed. The formation of vortex structures in the vicinity of the poles of the planets of the solar ...
