Advanced Simulator Power Flow Technology/Advanced Radiation Simulation Volume 3-Computational Methods for POS and Vacuum Power Flow

Abstract

This is the third of 3 volumes describing work for the Advanced Simulator Power Flow Technology/Advanced Radiation Simulation Program. This volume, for FY96, deals with analytical, computational and experimental studies of power flow in vacuum feed and switch regions of pulsed power, inductive energy store systems. Section 1 reports on the development and testing of algorithms for computing the electron magnetohydrodynamic Hall effect in MHD fluid codes. Section 2 contains numberical studies via Mach2 of coupled electron Hall and fluid flow effects in plasma opening switch experiments conducted in the parallel plate geometry of the Hawk generator. In Sections 3 and 4, respectively, Mach2 is applied to the analysis of freely expanding flashboard plasmas and of plasmas injected through the anode structure into the switch gap of ACE 4. Section 5 deals with experimental evidence indicating that switch voltage is limited by effects originating at the electrode surfaces and with physical models to quantify these effects. Sections 6 and 7 describe SPOCK, a user friendly code for rapid analysis of the pulsed power. Section 8 describes development of the triangular, unstructured grid, electromagnetic PIC code, TRIMAX, and its application to power flow studies in ACE 4.
