Abstract: 

Using the time domain analysis we studied the processes of oscillations build-up and spatial synchronization in FEL’s with two-dimensional distributed feedback driven by a large size sheet and tubular relativistic electron beams. It is proved that proposed feedback mechanism allows to ensure powerful spatial-coherent radiation when the ratio between transverse size of the electron beam and wavelength runs up 10^2 - 10^3.
