Microinstabilities in a Radially Contracting Inhomogeneous Cylindrical Plasma Slab. Part 2: Lower Hybrid and Electron Cyclotron Drift Instabilities in the Plasma Focus

摘要

The frequency, growth rate, turbulent electron and ion heating rates, and the effective collision frequency are calculated for both instabilities in parameter ranges associated with the late compression phase of the plasma focus. Simple analytical formulas were deduced for these parameters. Results indicate a regime in which the lower hybrid drift induced turbulence can heat the electrons up to a few keV within 10nsec. This result agrees with experimental observations.
