abstract = {{A modern trend in the next generation of X-ray Free Electron Lasers (FEL) is the development of tools for the investigation of dynamic processes on the (sub)atomic scale that requires photon beams with energies of 20-25 keV with a repetition rate of 1 MHz or higher. At reasonable energies of the drive linac of 8-10 GeV optimum FEL performance requires an electron beam with emittance of 0.1 mm.mrad or lower. Higher value of the emittance leads to essential degradation in FEL performance and significant increase in required undulator length. In this work we try to estimate the ultimate beam brightness and bunch repetition rate that may be achieved with existing electron injector technologies and outline possible ways of obtaining beams with the parameters required for future FELs. In particular, we will discuss possible injector designs for the ongoing UK XFEL project.}},
