Plasma Physics notes

Plasma Physics Exam 2024 1.5 Plasma Frequency The plasma frequency, 2 = ne2 , (1.5) ωp ǫ0 m is the most fundamental time-scale in plasma physics. Clearly, there is a different plasma frequency for each species. However, the relatively fast electron frequency is, by far, the most important, and references to “the plasma frequency” in text-books invariably mean the electron plasma frequency. It is easily seen that ωp corresponds to the typical electrostatic oscillation frequency of a...
