Radiation by electron bunching in large‐amplitude Langmuir waves

Strong plasma turbulence is produced by electron beams in plasmas and can result in intense broadband radiation above the plasma frequency. A possible mechanism for producing plasma frequency harmonics is the high‐frequency convective bunching of electrons in large‐amplitude Langmuir waves. Using a...

Description
Summary:Strong plasma turbulence is produced by electron beams in plasmas and can result in intense broadband radiation above the plasma frequency. A possible mechanism for producing plasma frequency harmonics is the high‐frequency convective bunching of electrons in large‐amplitude Langmuir waves. Using a model based on a localized, monochromatic wave solution, results for the spectrum of the radiation and its spatial distribution are derived.
