Abstract
The possible use of intrinsic synchrotron radiation of a cyclic FEL fo r the cathode illumination in the photoinjector - the electron source for the basic FEL electron accelerator - is analyzed. It is shown that it is necessary to collect the energy from the are which is much larg er than the intrinsic SR divergence and to use isochronous optics. A s imple algorithm is proposed to define the isochronously focusing surfa ce which transforms the SR evolvent to a compact area.
