Test-ion diffusion in a magnetized plasma
Particle cross-field transport is one of the important issues in understanding the physical behaviour of magnetised plasmas. In this study cross-field transport of barium test ions was investigated in a Q-machine plasma. Test particles were produced and tracked in their motion by an optical tagging method. The comparison between the measured tag signal and a simple theoretical simulation yielded a quantitative evaluation of the ion diffusivity. It was observed that the injection of different noble buffer gases modifies the plasma parameters in such a way that although the diffusion is supported by classical mechanisms, its magnitude is reduced considerably.
