ELECTROMAGNETIC STUDIES IN SHOCK PRODUCED PLASMAS
Abstract
A compilation is presented of the important aspects of an analytical and experimental study concerned with non-uniform plasmas. The experimental work was done using a shock tube to produce the plasma. A detailed description of the shock tube facility is presented. A spatially resolving electron density microwave diagnostic technique useful in a range of electron densities infrequently explored by other investigators was developed. This technique permits accurate spatial resolution in plasma gradients for electron densities, orders of magnitude below that possible, using a conventional microwave interferometer. The microwave instrumentation for this technique is described in detail. The analytical formulation correlating the measured properties to ascertain the electron density is shown. A summary is presented of the theoretical work conducted in conjunction with the experimental program. The generalized properties of non-uniform plasmas are given and referenced to the detailed formulations. The diffusion effects in a non-uniform plasma are outlined quantitatively. On the basis of the diffusion calculation, the electromagnetic properties of the plasma contained in the shock tube where radial non-uniformity exists are discussed.
