"Chaotic Phenomena in Plasmas "

Date of publication:

Aug. 1991

Key words:

chaos, sheath, electron-beam, RFP, dynamo, self-organization, stochastic magnetic field, alfven wave, Buneman instability


It has recently been recognized that the research on various aspects of chaotic dynamics grows rapidly as one of some areas in nonlinear science. On the other hands, the plasma has long been called a treasure-house of nonlinear phenomena, so it is easy to imagine that the plasma is abundant in chaotic phnomena. In fact, the research on plasma chaos is going on, such as the research on the stochastic magnetic field and the chaotic orbit in the toroidal helical system, as well as the research in other experiments. To review the present status of the research on plasma chaos and to make clear the basic common physics, a working group was organized in 1990 as a collaboration research of National Institute for Fusion Science. This is the report on its activity in 1990, with a stress on experimental data abtained in basic plasma experimets and RFP, and on the relaxed theories and computer simulations.
