HPM generation by use of resonant relativistic BWO driven by compact inductive energy storage

The paper describes the installation and experimental results of high-power microwave generation by a resonant relativistic BWO (3.6 GHz, TM/sub 01/) (Kitsanov, S.A. et al., Proc. 14th Int. Conf. on High Power Particle Beams, p.255-8, 2002) driven by a high-voltage generator based on inductive storage (cable line) and an electro-explosive opening switch. As a primary source, either capacitive storage (surge current generator) or magnetic cumulative generator (MCG) was used. For a cathode voltage of 700 kV and diode current of 9 kA, the peak microwave power reached about 0.5 GW and pulse duration was about 50 ns.
