Abstract:

Cable response due to X-irradiation is linear with incident fluence provided the deposited charge in cable dielectrics is directly proportional to the X-ray flux. In order to estimate the level at which the linear region ends, we discuss three nonlinear processes which modify the deposited charge profile in a hypothetical cable model field limiting in vacuum gaps, ionization effects in air gaps, and radiation-induced dielectric conductivity. The exact level, at which limiting of the Norton driver in an elemental length of cable begins, depends on the cable geometry and the X-ray source. Estimates of the onset of nonlinearities due to field limiting and to dielectric conductivity are found in terms of cable and source parameters. With air-filled gaps the Norton driver is always nonlinear. In addition to limiting of the Norton drivers, the load response of a long cable may be limited due to attenuation of propagating currents in the induced conductivity of the bulk of the dielectric.
