Results of Research on Overcoming Pulse Shortening of GW Class HPM Sources
Abstract
The RPM sources basic research program of the Air Force has a major emphasis on the pulse shortening problem. This includes collaborative work in universities and the Phillips Laboratory. We have demonstrated two fundamentally different RPM sources which radiate rf power in excess of 1 GW and are not limited by pulse shortening (up to our 300 nsec pulse length): the MILO and Injection Locked RICO. While the fundamental physics of these sources are different, they both have generated in excess of 100 J. We will discuss the physics of how the pulse shortening was eliminated, up to the limits of our pulse power-driver. We report on experiments and computer simulations investigating techniques to overcome these pulse shortening issues. We also report on our plans for the coming year to try and extend the electron beam (to 600 nsec) and rf pulse length (up to 500 nsec).
