Abstract :
Possibility of generation of multi-megawatt terahertz pulses based on undulator and Cherenkov mechanisms of superradiance from electron bunches formed by photo injection guns has been studied. Theoretical analysis was performed in the frame of average approach and confirmed by direct PIC simulations.
