| Zusammenfassung |
| Langmuir wave turbulence generated by a beam-plasma interaction has been studied
since the early days of plasma physics research. Despite a long history of
investigation on this subject, among the outstanding issues is the generation of
harmonic Langmuir waves observed in both laboratory and computer-simulated
experiments. However, the phenomenon has not been adequately explained in terms
of theory, nor has it been fully characterized by means of numerical
simulations. In this paper, a theory of harmonic Langmuir wave generation is put
forth and tested against the Vlasov simulation results. It is found that the
harmonic Langmuir mode spectra exhibit quasi power-law feature implying a
multi-scale structure in both frequency and wave number space spanning several
orders of magnitude. |
