Monte Carlo Calculations on the Direct Cable Drive Due to Gamma Radiation.

Abstract

Two Monte Carlo codes, labeled MCABLE and MCIMP, were developed to determine the direct drive currents in cables due to gamma radiation. MCABLE was written in cylindrical coordinates for circular shaped cables and MCIMP in Cartesian coordinates for any arbitrary shape. A background into single and multiple scattering theory with an emphasis on the Moliere and Scott-Snyder distribution functions is presented. Range and emission current calculations are provided to substantiate the validity and accuracy of the technique used in the Monte Carlo codes. An experimental comparison was also made to verify the accuracy of the codes. A parametric study was conducted on the response of a coaxial cable due to variations in the dimensions and material types. Based on this study, a simple model for estimating the shield and center conductor currents is presented. Finally, a comparison is made between the response of eight cables measured in the laboratory and the Monte Carlo code MCABLE.
