Measured and Predicted Radiation-Induced Currents in Semirigid Coaxial Cables

Variations in the X-ray-induced response of a number of semirigid coaxial cables are reported. Irradiation spectra were obtained by filtering the radiation from a dense plasma focus device. Semirigid cables of different size, material, and impedance were tested. Minute gaps and conductor flashings were found to be dominant factors affecting cable response. Response predictions provided by the MCCABE computer code closely correlated with the experimental measurements.
