Langmuir turbulence and quasilinear interactions of a hot electron beam in the inhomogeneous solar corona plasma with a uniform electric field

摘要

Using numerical simulation of the quasilinear equations, the propagation of an electron beam through inhomogeneous solar corona plasma and generation of Langmuir waves are investigated by taking into account a uniform electric field. The level of the excited Langmuir waves is remarkably enhanced by decreasing density and the applied electric field. The mean velocity of propagation of the beam is not a constant and decreases with distance from the injection point. The effect of the electric field is more pronounced on the slow electrons and accelerates them to high velocity region while the density gradient mainly affects the fast electrons and effectively decelerates them.
