Using the Plasma Noise Spectrum to Measure the Parallel Temperature in a Nonneutral Plasma
Abstract
A simple, non-destructive diagnostic for the temperature of a non-neutral plasma is desirable as plasma lifetimes increase and the confined species become more exotic. If the confinement system includes an isolated wall sector, the motion of the charges beneath that sector will result in a noise signal that can be directly related to the velocity distribution of the confined particles. Care must be taken to differentiate the resulting plasma signal from the instrumental noise spectrum and the strong signals from plasma oscillation modes. The theoretical basis of the relationship between the noise spectrum and the temperature as well as experimental results are presented.
