STUDY OF PULSED RADIATION EFFECTS ON MICROWAVE FERRITE DUPLEXERS
Abstract
Experiments were performed to obtain data regarding air ionization susceptibility of various cable typ s and configurations and radiation effects caused by irradiation of individual operating ferrite duplexer components. Procedures are described for testing C-band microwave coaxial ferrite Y-junction circulators, gyromagnetic-coupling limiters, and ferrite isolators during the initial series of experiments conducted at Sandia Pulsed Reactor Facility. Photographs of oscilloscope traces showing radiation effects on operating characteristics of these components are presented. Quantitative interpretations of the data obtained by circuit calibration procedures are also presented. The radiation effects on two types of cable configurations - flexible RG-5B/U and semi-flexible Spirafil are also displayed pictorially and reported quantitatively. Note is made that the air dielectric Spirafil cable increases in breakdown susceptibility with a decrease in internal air pressure. Results of dosimetry provided by the SPRF are tabulated along with components investigated in each test. (Author)
