Book Description
We have performed a series of experiments to study the damping effect of the ion acoustic waves. The experimental results have been analyzed both qualitatively and quantitatively based on the theory by Basu and Jasperse. The analysis shows that the theoretical and experimental results agree very well under certain conditions.

Book Description
The general propagator expansion method is used for the study of the collision effects and the Fokker-Planck kinetic equation is employed for several collisional processes. In drift-free plasma, the studies show that the plasma may become unstable if e-i collision growth can overcome Landau damping and other collision damping. The contamination can affect ion acoustic waves significantly and a small amount of light ion contamination can cause much higher damping. For our experiment on the ion acoustic waves in drift-free plasma, the experimental results are explained with the consideration of collision and contamination effects and are close to our theoretical results. For a plasma with a quasi-static electric field, two ion acoustic modes may propagate in a single ion species plasma. This ion-acoustic instability associated with the slow mode is a kinetic instability and is caused by the interaction of ions and electrons. In our experiment, the fast mode is found and the measured results agree with the theoretic values. In a two-on-species plasma, the velocity differences between the ion species can cause the ion-ion two-stream instability. This is a fluid instability and only exists in a range of ion drift velocities and wave frequencies. An experiment was performed to study ion-ion two-stream instability. The unstable waves generated by the ion beams are observed as predicted by theory and coincide with the kinetic dispersion relations for the ion-ion two stream instability.

Book Description
A nonlinearity is one of the most important notions in modern physics. A plasma is rich in nonlinearities and provides a variety of behaviors inherent to instabilities, coherent wave structures and turbulence. The book covers the basic concepts and mathematical methods, necessary to comprehend nonlinear problems widely encountered in contemporary plasmas, but also in other fields of physics and current research on self-organized structures and magnetized plasma turbulence. The analyses make use of strongly nonlinear models solved by analytical techniques backed by extensive simulations and available experiments. The text is written for senior undergraduates, graduate students, lecturers and researchers in laboratory, space and fusion plasmas.
