New Ideas for Advanced Relativistic Magnetrons
Abstract
The generation and transmission of pulses of microwaves (ultra-wideband, Sband, L-band)with peak power of 100 MW 10 GW and pulse duration of 10-9 s 10-6 s define the field of High-Power Microwaves (HPM). For almost 50 years, HPM research has been conducted in manyuniversities and national laboratories (USA, UK, France, Germany, Russia, Japan, China, Indiaand Israel, among others) resulting in great progress and understanding of the processes thataccompany the generation of such high-power microwave pulses. The main motivation for thiscontinuing research is defense applications, for the partial or complete disruption of modernelectronic systems locally or over large areas, neutralizing explosive devices, protecting aircraftfrom surface-to-air missiles, and improved time- and space-resolved radar systems. In the modernage of digital warfare, HPM methods are still attractive offensive means as these are independentof the specific digital controls used in each electronic system.Relativistic magnetrons are the most advanced, compact and efficient candidates for suchpurposes. The University of New Mexico (UNM) group has made major advances in this fieldwhich brought relativistic magnetrons to very high efficiencies and compactness. The TechnionHPM group has made significant contributions to this field as well. The groups have long standinghistory of collaboration. Recent work in which it was proposed that a low energy high densityelectron cloud, a squeezed state, can be used as the source for such magnetrons has triggered newideas which seem to be very promising. These ideas should avoid the formation of the expandingcathode plasma in a relativistic magnetron which short it and avoid the repetitive use of suchdevices. The proposed project will focus on proving this concept. This proposal seeks funding forthe Technion group to support a collaborative study with UNM to realize these ideas.
