It is well known that such a low-frequency plasma instability behaves as a Van Der Pol oscillator with instability frequency [[omega].sub.0] [34-52].
The plasma instability is enhanced in the vicinity of the high-temperature peak.
Keen and Fletcher reported that the method of "asynchronous quenching of a Van Der Pol oscillator" might be used to suppress (or quench) a plasma instability [37].

The concept of absolute and convective instabilities was first put forward by Briggs [14] in the study of plasma instability and then introduced to classical hydrodynamic stability [15].
The upgrade will enhance the capabilities of NSTX by upgrading the magnet system to permit higher plasma currents and magnetic fields and by installing a second neutral beam heating system to enable better control of plasma instability.
Designed as a reference but also suitable for classroom use, this covers the main characteristics and processes of the regular ionosphere, nonlinear phenomena and plasma instability in the disturbed regular ionosphere, radio signal presentation in the ionospheric communication channels, evaluation of plasma irregularities in the ionosphere, modern radiophysical methods of investigation of ionospheric irregularities, performance of radio communications in ionospheric channels, optical and radio systems for investigation of the ionosphere and ionospheric communication channels, and the performance of land-satellite communication links passing through the irregular ionosphere.
Experiments on the Nike KrF laser have explored the 1015-1016 W/cm2 intensities used in these designs, and support the expectation that KrF laser light suppresses laser plasma instability. Shock Ignition designs have predicted gains similar to Fast Ignition, but do not need a multi-petawatt laser or complex targets.
