Description

With the availability of very high power (~$10^{9}$ W) and short duration (≤$10^{-9}$ s) microwave sources it is possible to study the non-linear interaction of powerful EM waves with under dense plasmas in a regime not studied so far. In contrast to the laser-plasma wakefield experiments, this approach addresses a significantly lower power, plasma density and electric field gradient regime but a larger time and space scale which allows for a more accessible experimental platform. We have built a super-radiant BWO, supplying microwave pulses of ~1 ns duration, ~0.7 GW power and ~10 GHz frequency which we intend to apply at the upstream end of a cylindrical waveguide filled with plasma of $10^{11}$-$10^{12}$ $cm^{-3}$ density. We present a model which describes the physics of the formation of the wakefield traveling in the waveguide and Lsp-PIC simulations to verify the feasibility of our experiment.
