Title: Hybrid Simulation of the Nonlinear Evolution of a Collisionless, Large Larmor Radius {ital Z} Pinch

Abstract

A two-dimensional, quasineutral hybrid code has been used to study the evolution of a {ital Z} pinch in which the ions are collisionless and have Larmor radii comparable to the pinch radius. The ions are treated as in a particle-in-cell model while the electrons are included through a simple fluid equation. {ital m}=0 instabilities are observed with the correct linear growth rates. These instabilities continue to grow exponentially, i.e., without saturation, until the plasma column is disrupted. {copyright} {ital 1996 The American Physical Society.}
