SOME NONLINEAR PROPERTIES OF ELECTRON-HOLE PLASMAS SUSTAINING THE HELICAL INSTABILITY,
Abstract
There are several areas of qualitative agreement among the non-linear properties of the helical instability in electron-ion and electron-hole plasmas. These include (1) a similar dependence of E on B throughout the range of B up to several times Bth; (2) regions of a linear increase in frequency as a function of B; (3) the reoccurrence of a nearly homogeneous plasma at some B > Bth; (4) turbulent behavior under highly supercritical conditions; (5) the form of the dependence of the helix self-B on the applied B; and (6) the occurrence of two magnetic field thresholds in a constantly increasing dB/dt. Some nonlinear properties of electron-hole plasmas appear to be unique: (1) the occurrence of several frequency modes as a function of B including three distinct types of transitions between these modes and (2) the relatively large self magnetic fields produced by the helical instability.
