Structures’ formation in inhomogeneous plasma excited by thin modulated electron beam
Interaction of thin modulated electron beam with inhomogeneous non-isothermal plasma is studied using 2D PIC electrostatic simulation. On the early stage of interaction intensive HF oscillations of electric field are observed in local plasma resonance region. Pondermotive force of these oscillatio...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Interaction of thin modulated electron beam with inhomogeneous non-isothermal plasma is studied using 2D PIC
electrostatic simulation. On the early stage of interaction intensive HF oscillations of electric field are observed in
local plasma resonance region. Pondermotive force of these oscillations disturbs an initial profile of plasma density.
On the later stage of interaction ring-like pulse of plasma density propagates out of the resonance region. Velocity of
this pulse depends on its intensity and exceeds the ion sound velocity. This fact demonstrates the nonlinear nature of
the pulse |
