  • Characteristic properties of the three-half-turn-antenna-driven RF discharge in the Uragan-3M torsatron 
    Chechkin, V.V.; Grigor’eva, L.I.; Grekov, D.L.; Pavlichenko, R.O.; Lozin, A.V.; Kasilov, A.A.; Beletskii, A.A.; Kozulya, M.M.; Kulaga, A.Ye.; Zamanov, N.V.; Tarasov, I.K.; Mironov, Yu.K.; Romanov, V.S.; Voitsenya, V.S. (Вопросы атомной науки и техники, 2014)
    In the λ = 3 Uragan-3M torsatron hydrogen plasma is heated by RF fields in the Ålfven range of frequencies (ω≤ωсi). Plasma with the mean density ‾ne units of 10¹² сm⁻³ is produced by the frame antenna and used as an initial ...
  • Effect of the lower hybrid heating on the confinement of high energy ions in stellarators 
    Grekov, D.L.; Smirnova, M.S. (Вопросы атомной науки и техники, 2002)
    In a stellarator-type device, the effect of the lower hybrid (LH) heating on the ion confinement is investigated. For this purpose, the motion of high energy ions is simulated numerically in the Large Helical Device, as ...
  • Features of coaxial waves in magnetized plasma cylinder 
    Grekov, D.L.; Lapshin, V.I. (Вопросы атомной науки и техники, 2000)
    The resonance properties of plasma cylinder are carried out for nonzero axial wave vector. Waves with frequency greater then ion cyclotron frequency but less then electron frequency are considered. From Maxwell equations ...
  • ICRF mode conversion efficiency in a two-ion component plasma of a tokamak 
    Grekov, D.L.; Kasilov, S.V.; Tretjak, K.K. (Вопросы атомной науки и техники, 2011)
    Mode conversion of fast magnetosonic wave (FMSW) into a short-wavelength wave is studied in the presence of ion cyclotron absorption and direct electron damping in a tokamak plasma. In plasmas with two (a majority and a ...
  • Influence of the frame-type antenna on the RF-discharge peripheral plasma parameters in the Uragan-3M torsatron 
    Leleko, Ya.F.; Grigor’eva, L.I.; Chechkin, V.V.; Grekov, D.L. (Вопросы атомной науки и техники, 2017)
    A qualitative evaluation is made of what changes of the electric potential near the frame-type antenna occur under the influence of following effects: the ponderomotive Miller force, which acts on plasma electrons near the ...
  • Microwave Reflectometry in Fusion Devices 
    Grekov, D.L. (Радиофизика и радиоастрономия, 2000)
  • Modelling of ICRF heating and current drive in tokamak plasma with two ion species 
    Grekov, D.L.; Kasilov, S.V.; Tretiak, K.K. (Вопросы атомной науки и техники, 2013)
    Fast magnetosonic wave propagation in real tokamak geometry is studied using a 2D finite difference code. Propagation and absorption of converted small scale waves is treated with help of the ray tracing code. Driven current ...
  • Ray tracing analysis of slow wave heating in the ion cyclotron range of frequencies in Uragan-3M torsatron 
    Tretiak, K.K.; Grekov, D.L. (Вопросы атомной науки и техники, 2016)
    Ray tracing analysis of slow waves (SW) propagation and absorption was used to obtain a qualitative description of ICRF heating by Frame-Type Antenna (FTA) in Uragan-3M torsatron. These issues were studied using ray ...
  • RF field pattern in the plasma cylinder of finite length for various antennas 
    Grekov, D.L.; Sklyarov, D.V. (Вопросы атомной науки и техники, 2005)
    The paper deals with numerical calculations of electromagnetic fields, which are launched in the plasma cylinder of finite length surrounded by metal vessel. The RF antenna is located at the end face of the cylinder and ...
  • RF way of impurity fluxes control in tokamaks 
    Grekov, D.L.; Kasilov, S.V. (Вопросы атомной науки и техники, 2000)
    We have studied the influence of the local heating on the impurity flows in tokamaks in the Pfirsch-Schluter regime. If the effect of the thermoforce on the impurity ions is included into consideration, the impurity flux ...
  • The HF field pattern in the magnetized plasma cylinder of finfte lenght
