Abstract :
Using time domain analysis we have studied the processes of oscillation build-up and spatial synchronization in FELs with two-dimensional distributed feedback driven by large size sheet and tubular relativistic electron beams. It is proved that the proposed feedback mechanism ensures powerful spatially coherent radiation when the ratio between the transverse sized of the electron beam and the wavelength is up to 102–103.
