Model of radiation electrization of low-pressure polyethylene films with controlled conductivity

摘要

The issue give a possible solution of the problems concern mathematical and computer simulation of radiation electrization of composite dielectric polymer films with controlled conductivity, capable of providing a drain of a charge accumulating under the action of cosmic plasma is reveal. Models and theoretical approaches were considered to calculate the electrization of polymer films, which are irradiated with ionizing radiation with different dose rates. A physic-mathematical model of radiation electrization of composite dielectric polymer films with controlled conductivity was proposed, taking into account the time-varying value of its radiative conductivity. It is shown that when the radiation conductivity is commensurable with the dark conductivity, it substantially slows down the increase of the electric field strength at radiation electrization.
