电缆X射线辐射感应电导率引起的非线性效应
Nonlinear effect caused by radiation-induced conductivity of cable irradiated by X-ray
摘要
Abstract
Nonlinear response of cable irradiated by X-ray is simulated using numerical method.The physical processes of the X-ray irradiating to cable are analyzed.Norton-equivalent driver model is built up for coaxial cable or shielded multi-cable based on 2-dimension finite-element method,focusing on dielectric’s radiation-induced conductivity effect.The nonlinear respon-ses of Norton-equivalent driver are calculated and their regularities are concluded in detail.The simulation result showed that the current amplitude would reach a saturation value as the X-ray fluence increased when induced conductivity existed.For some types of cable,there would be 3 different current peaks appearing successively at different point on the waveform while the X-ray fluence increased.关键词
