Title: Magnetic plasma expulsion

Abstract

Magnetic confinement of plasmas is widely studied for restricting a plasma's extent to a given region. Presented is one scheme for what is referred to as magnetic plasma expulsion, which would prevent the plasma from entering a given region. Magnetic plasma expulsion techniques may allow instrumentation access to the interiors of plasmas. Magnetic plasma expulsion techniques may also make alternative approaches for magnetic plasma confinement possible. Particle-in-cell simulation with the Warp code is used to study magnetic plasma expulsion. Some conditions for achieving magnetic plasma expulsion are reported.

FIG.  1 FIG. 1: Illustration of an alternative plasma confinement approach consisting of two coaxial solenoids. (a) The cylindrical material surfaces of two metal tubes cross the space between the solenoids. These cylindrical material surfaces could enclose mechanical supports and electrical connections to the inner solenoid. (b) The magnetic field produced bymore » the two coaxial solenoids. The outer solenoid is not shown. Plasma would be confined along closed magnetic field lines that enclose the inner solenoid. Two methods would be used to mitigate the loss of plasma particles to the cylindrical material surfaces. Magnetic mirrors would be formed from a field strength gradient along field lines between points within the interior solenoid, where the field is weaker, and points between the solenoids, where the field is stronger. Loss of plasma to the cylindrical material surfaces that cross the space between the two solenoids would also be inhibited by the use of magnetic plasma expulsion to redirect magnetic field lines around the cylindrical material surfaces.« less
