Ultrahigh Power Cherenkov Oscillators Simulation and Parameters Optimization

Considered in this paper are the features of Cherenkov oscillators simulation. The variants for electron beam accelerating voltage 250kV and a current 1-2kA are discussed. Using of ultrahigh power microwave impulses Pu=1-3 GW with duration tau_u=0.5-5 mus within lambda=1-10 cm band makes it possible to implement effects electromagnetic defeat. Long-term experimental and theoretical research of different types of microwave oscillators has shown, that in order to achieve specified radiation parameters the Cherenkov oscillator should be used. Presented are the models and efficient techniques, which allow to carry out complete optimization of electrodynamic system profile (calculation takes about 30 seconds). That would make for discovery of new design types. Considered in this paper are simulation features and the new oscillators for electronic beam with the given accelerating voltage 250kV and current 1-2kA are discussed.
