Abstract

The technique known as optical tagging provides information on particle orbits in experimental studies of both collisional and collisionless plasmas. The extension of the technique presented here uses the degree of spin polarisation of the ionic ground-state as a means of tagging particles. This may be applied to ions which do not have a convenient metastable state and hence can usefully be applied in non-neutral plasmas where the ion confinement time may exceed the metastable lifetimes. This is illustrated by an investigation of the tag particle transfer function for a linear magnetised plasma. In addition, optical pumping of ionic spin states should allow quantum interference experiments to be carried out in plasmas.
