Circuitry and Operation of an X-Band Interferometer for Shock-Tube Measurements Using the Dielectric Slab Approximation

摘要

The experimental methods and equipment used in analyzing transient shock-generated plasmas by X-band microwave interaction techniques are presented in considerable detail. A transmission technique (for electron densities of 10 to the 10th power to 10 to the 13th power electrons/cc) and a reflection technique (extending the range to about 10 to the 16th power electrons/cc) are discussed with respect to the construction and adjustment of the microwave apparatus and the required data reduction. An evaluation of the experimental errors due to the electronic equipment and data reduction procedure is given. (Author)
