Research on this grant has focused on plasma focus experiments in the areas of particle-beam generation and as a potential repetitive opening switch. In pursuing the former, unique diagnostic tools were developed to measure the scaling of particle-beam current and energy for both the electron and ion beams generated by the device. Simultaneous measurements of the energy spectra for both the electron and ion beams were measured for the first time as were scaling laws for the increase of electron energy and current with input energy. The potential of the plasma focus as an opening switch was then investigated. Measurements of the current and voltage waveforms indicated that the resistance of the pinch was roughly ten times the classical value estimated from electron-temperature measurements and streak pictures. To increase the efficiency the impaler concept was devised which could have a transfer efficiency of well over 50% according to the results of a physical model. The frequency of the microwave emission was measured using the delay line technique. The observed frequencies were most consistent with the lower hybrid frequency.
