Final Technical Report
Abstract
The purpose of this grant was to experimentally investigate asymmetry-induced radial transport in a non-neutral (Penning-Malmberg) plasma trap. These traps provide an excellent platform for transport studies since the plasmas are generally well confined. One can then study transport in a controlled manner: the plasma is perturbed and the resulting transport measured. The focus of this research is the transport produced by applied asymmetric electric fields. The main results of our research concern (1) the theory of asymmetry-induced transport, (2) an absolute comparison of theory predictions with experimental results, (3) the amplitude scaling of the transport, (4) the frequency dependence of the transport, (5) the development of techniques to determine the relative contribution of mobility and diffusion to the transport, and (6) measuring the effect of small axial magnetic variations on the transport.
