  • Design of a gas cell for laser wakefield acceleration of electrons 
    Golovanov, A.A.; Lebedev, V.S.; Kostyukov, I.Yu. (Вопросы атомной науки и техники, 2018)
    Laser-wakefield acceleration of electrons in a gas cell is considered. The OpenFOAM package is used to study the influence of the parameters of the cell on the density profile. Particle-in-cell simulations of laser ...
  • Growth rate of QED cascades in a rotating electric field 
    Kostyukov, I.Yu.; Artemenko, I.I.; Nerush, E.N. (Вопросы атомной науки и техники, 2018)
    QED cascading in a rotating electric field is studied. The cascade growth rate is derived from kinetic equations for electron-positron pairs and photons as a function of the field strength. The rate is in an agreement ...
  • Particle beams from laser-irradiated solids at ultrahigh intensities 
    Nerush, E.N.; Kostyukov, I.Yu. (Вопросы атомной науки и техники, 2013)
    Laser-solid interactions at the intensity range 10²³…10²⁶ W cm⁻² and the plasma density about 10²⁴ cm⁻³ are studied by means of numerical simulations. This range of parameters is extremely important for various laser ...
  • Pic simulation of electron acceleration in a wake field generated by a high-power laser pulse in plasma 
    Kostyukov, I.Yu.; Vvedenskii, N.V. (Вопросы атомной науки и техники, 2006)
    Acceleration in a plasma wake field is simulated with 2D axially symmetric hybrid PIC code. The dependence of the parameters of the accelerated electrons on the laser pulse duration (at a given pulse energy) is studied ...
  • Relativistically induced transparency and compressed fusion targets 
    Pukhov, A.M.; Kostyukov, I.Yu. (Вопросы атомной науки и техники, 2013)
    We study impact of QED effects on relativistically induced transparency in plasma. The relativictic induced transparency is the key phenomenon in the fast igntion schemes for Inertial Confinement Fusion. We have simulated ...
  • Short-time particle motion in strong standing electromagnetic wave 
    Bashmakov, V.F.; Bashmakov, V.F.; Nerush, E.N.; Kostyukov, I.Yu. (Вопросы атомной науки и техники, 2013)
    The particle motion in the standing electromagnetic wave was investigated on the times much shorter than the wave period. Cases of circular and linear polarizations are considered. The first nonvanishing coefficients in ...
  • Synchrotron radiation losses in laser-plasma accelerators 
    Kostyukov, I.Yu.; Nerush, E.N.; Pukhov, A. (Вопросы атомной науки и техники, 2006)
    Like in conventional accelerators, a synchrotron radiation can significantly suppress an acceleration in a bubble. The dynamics of accelerating electron in the bubble with consideration of the synchrotron radiation reaction ...
