Abstract
In continuation of the work by Decker et al. on current and neutron yield scaling of plasma focus devices, analytical solutions for the circuit equation with finite resistence R {ne} 0 in the run-down phase, and with R = 0 in the compression phase were derived. There follows an analytical scaling theory for maximum pinch currents under influence of finite resistance. Further, the two-dimensional three-fluid MHD-Code of the work by Behler was extended to the determination of the resistence R. Using this MHD-calculations, the conditions imposed on the model solutions, i.e. constant axial velocity and constant resistence in the run-down phase, were found to be acceptable. The analytical determined values for discharge current are compared with MHD-calculations and experiment. (orig.).
