Description
Summary:A numerical approach for determining the current on an wire in an ionizing radiation environment has been developed. This algorithm integrates Maxwell's equations along with Newton's Law for the primary electrons and the air chemistry equations for the secondary electrons in a one-dimensional cylindrical retarded time coordinate system. The algorithm is then used to predict the fields and air conductivities near a thin wire illuminated by a transient radiation pulse. It is shown that the air conductivity and radial electric field near the wire are significantly changed when the primary Compton ionization electrons are treated self-consistently as opposed to a prescribed source approach.
