Abstract
This report presents a summary of work on the physics of the dense plasma focus carried out by the plasma focus team of the Institut fuer Plasmaforschung in Stuttgart. Particularly, the calculations with MHD codes, model theories and the development of a quasi-analytical method for the solution of systems of partial differential equations led to the theoretical description of plasma focus dynamics, scaling laws with particular consideration of the tendency to high voltage energy storages, the prediction of neutron production and filamentation in the pinch phase for large currents (> 500 kA). Various short time diagnostic methods were developed and applied to the determination of plasma parameters in the plasma focus experiment. Among these were time-resolved neutron spectroscopy, shadowgrahy, Mach-Zehnder interferometry and holographic interferometry, Thomson spectrometry especially for analyzing high energy deuterons and reaction protons, as well as various probe measurement techniques. While overall dynamical phenomena of the plasma focus are now well understood, the phenomena during breakdown, spoke formation, electrode phenomena, filamentation in the pinch phase, build-up of high electric fields and particle acceleration in the pinch phase and saturation of neutron production, to name the more important problems, still warrant clarification.
