Test particle - plasma interactions

Gibson, Alasdair L. (1973) Test particle - plasma interactions. PhD thesis, University of Glasgow.

Abstract

This thesis describes investigations into the properties of a two-dimensional plasma carried out by theory and computer simulation. The predictions of previous work concerning the wake generated by a suprathermal test particle in a two-dimensional plasma have been verified within the very noticeable constraints of the computer simulation model. Other work has been done, which has lent itself better to a good description by simulation. Primarily, in the electrostatic case, the slowing of a test particle in a two-dimensional collisionless plasma has been adequately quantitatively demonstrated. In the case of two-dimensional magnetised plasma, expressions for the potential due to a test charge have been derived. It is shown that the nature of the potential distribution round the test particle, and a fortiori, the shielding properties of the plasma have been radically altered by the inclusion of the magnetic field. Whatever tractable means were available have been used to indicate the form of the potential distributions for both stationary and moving test particles.
