Considerations in Comparing Experimental Results and Theory of Biased Impedance Probes
Abstract
This note discuses two outstanding problems that have been present for a number of years in the Space Physics Simulation Chamber groupswork on impedance probes. These are, (a) impedance curves indicative of a much higher energy absorption than can be accounted for usingstandard collision models given the plasma parameters, and (b) divergence at low frequency between predicted and measured impedance curvesusing our linear model. We compare numerical results of our different models to experimental data to determine under what conditions suchmodels are valid and what areas are in need of improvement.
