  • Conductivity of an ion-acoustically turbulent plasma 
    Krishan, V (D.Reidel Publishing Co.,, 1978-09)
    Three different mechanisms are suggested for the non-linear saturation of the ion-acoustic instability. These include the indirect wave-particle interaction, the scattering on density fluctuations and the effects of energy ...
  • Direct generation of electromagnetic radiation from a beam-plasma system 
    Krishan, V (Institute of Physics, 1980-02)
    A possible mechanism for the direct generation of electromagnetic modes of frequencies near the electron plasma frequency, is suggested. The spatial variation of the interplanetary magnetic field seems to play an essential ...
  • Nonlinear analysis of two contra-streaming electron beams - plasma system 
    Krishan, V (D.Reidel Publishing Co.,, 1978-08)
    The nonlinear theory of electromagnetic modes in the radio frequency range, excited from a system consisting of two contra-streaming electron beams, supports the experimental observation that out of w~(n + ½)w/subce,w = ...
  • Observations and interpretation of solar decameter type IIIb radio bursts 
    Krishan, V; Subramanian, K. R; Sastry, Ch. V (Kluwer Academic Publishers, 1980-06)
    Solar decameter bursts of Type IIIb are observed with a multichannel radiometer at wavelengths around 12m. The time and frequency resolutions were 10 ms and 100 kHz. Observations on the time structure of these bursts are ...
  • On the correlation between exciter duration and decay constant of solar decameter Type III radio bursts 
    Subramanian, K. R; Krishan, V; Sastry, Ch. V (Kluwer Academic Publishers, 1981-04)
    It is observed that while there exists a strong correlation between the decay constant and the exciter duration for isolated type III radio bursts, it is absent for those type III radio bursts which are preceded by type ...
  • Plasma acceleration by ion-acoustic turbulence 
    Krishan, V (Kluwer Academic Publishers, 1980-12)
    An energetic proton beam passing through a stationary ionized medium, excites ion-acoustic turbulence. The ion-acoustic instability saturates due to the non-linear indirect wave-particle scattering. The electric field ...
  • Radiation from an electron beam-magnetoplasma 
    Krishan, V (Institute of Physics, 1980-08)
    The possibility of direct generation of electromagnetic radiation at and near electron plasma frequency from an electron beam-magnetoplasma system is explored. The role of the electron beam is replaced by the electron ...
  • Radio frequency emission in electron beam-plasma and beam-beam interaction 
    Krishan, V; Sinha, K. P; Krishan, S (D.Reidel Publishing Co.,, 1978-01)
    A linear excitation of electromagnetic modes at frequencies ~_ (n+1/2)ωce , in a plasma through which two electron beams are contra-streaming along the magnetic field is investigated. This may be a source of the observed ...
