Non-linear dynamics of non-neutral plasmas

Abstract: An expanding or contracting non-neutral plasma without an external magnetic field is investigated. In certain situations the density and temperature rise to many times their initial values in a short time. followed by an equally sharp fall. The plasma shows no Landau damping.

“…The evolution of collisionless, non-neutral plasma in an electrostatic or magnetic trap is an interesting case of complex physical system far from equilibrium where depending on the initial conditions and parameters of the external trapping fields some dynamical structures are formed in phase space by the nonlinear wave-particle interactions [1] - [4]. It means that there are many ways for evolution of the non-neutral plasma system from the initial state far from equilibrium to a state, where the distribution function practically ceases to change with time.…”

“…It is well known that to obtain exact nonlinear solutions even for a simple plasma system with arbitrary initial/boundary conditions is generally difficult. In order to investigate the possibility of steady states, waves and patterns for such system it would be useful to consider the dynamical properties of physically more simple system but in a fully nonlinear formulation [5,6]. In the present paper we are going to study the case in one dimensional geometry for the cloud of the single charged particles without external trapping field.…”

“…Solving the reactor power balance equations (such as in Ref. [5], for example) leads one to the conclusion that achieving the required auxiliary current drive figure of merit γ cd will be 'challenging'. Clearly, a large pressure driven current fraction f p is highly desirable.…”
