High Power Microwave Generation From A High Current Diode

Over its three year period, this AASERT grant supported a large number of undergraduate and graduate students at various levels at the University of Michigan. The supported students are all US citizens. Their major achievements include: (1) First applications of time-frequency analysis to a high power gyrotron and to a conventional magnetron. (2) An in-depth analysis of transient limiting current in a diode. (3) Spectroscopic analysis that identifies water as a major culprit that triggers pulse shortening in HPM sources. (4) Initiation of an experiment of multipactor on a dielectric. (5) In-depth study of AC Stark broadening and its application to HPM.
