Abstract：
Particle simulation results of coherent stimulated radiation from subnanosecond electron bunches moving through a periodic waveguide and interacting with a backward propagating TM₀₁ wave are presented. The longitudinal guiding magnetic field is 1.8T, the peak power as high as 100 MW for the 300ps pulses at 38GHz. The mechanism of microwave pulse generation was associated with the mutual influence of different parts of the electron pulse due to slippage of the wave with respect to the electrons; The dependence of peak power on the square of the total charge is almost linear, it means that all electrons of e-bunch radiate coherently. This can be interpreted as superradiance.
