A nonlinear beat-wave regime of plasma wave excitation is considered. Two beat-wave drivers are considered: intensity-modulated laser pulse and density-modulated (microbunched) electron beam. It is shown that a long beat-wave pulse can excite strong plasma waves in its wake even when the beat-wave frequency is detuned from the electron plasma frequency. The wake is caused by the dynamic bistabi...

The solar corona is a very dynamic plasma on time scales of decades to a few milliseconds. Radio missions provide diagnostic tools particularly suited for the analysis of non-thermal electron distributions, enhanced levels of various kinds of plasma waves and plasma phenomena related to electron acceleration in flares. Very intense coherent emissions are observed at frequencies below about 3GHz...

where Ω is a bounded domain of R, n ≤ 2 with κ, α, λ > 0. The variable ψ stands for the dimensionless low frequency electron field, whereas φ denotes the dimensionless low frequency density. This system in one dimension describes the nonlinear interaction between high frequency electron waves and low frequency ion plasma waves in a homogeneous magnetic field, adapted to model the UHH plasma hea...

These proceedings contain fifty-one papers presented at the "3rd International Conference on Quiescent Plasmas". The papers are arranged according to the following subjects: Plasma Production, Ion Waves, Electron Waves, Drift Waves, Non-Linear Effects, and Special Topics. To facilitate reproduction and speed up publication, the papers are reproduced directly from the best available copies, and ...

Blackbody levels of emission in the electron cyclotron range of frequencies have been observed from an overdense (vpe;3vce) Madison Symmetric Torus @Dexter et al., Fusion Technol. 19, 131 ~1991!# reversed field pinch plasma, a result of electrostatic electron Bernstein waves emitted from the core and mode converted into electromagnetic waves at the extreme plasma edge. Comparison of the measure...
