Abstract
Cross-field transport of test ions is investigated in a linear Q-machine plasma. Test particles are created and followed in their motion by an optical tagging diagnostic scheme. Direct information on ion diffusivity is obtained from a comparison between the actual tag signal and a simple theoretical simulation. Diffusion is demonstrated to be supported by classical mechanisms. When different noble buffer gases are injected, the plasma reacts in such a way that the diffusivity remains classical but its magnitude is considerably reduced. (author) 9 figs., 15 refs.
