SGEMP Phenomenology and Computer Code Development

Abstract

Two new computer codes, DYNA2CYL and DYNASPHERE, have been developed for use in system-generated EMP (SGEMP) and internal EMP (IEMP) problems. The code DYNA2CYL solves Maxwell's equations dynamically and self-consistently in two dimensions (r and z) in the region between two concentric cylinders of finite length. The calculations are for end-on irradiation of the cylinders, which is simulated by specified emission of electrons from either or both the outer and inner cylinders into the cylindrical cavity. The two cylinders can be isolated from one another or connected by an arbitrary load. The outputs of the code are fields and currents on the inner and outer cylinders, the potential difference between the two cylinders, and the current through the load between the cylinders.
