Abstract
Several laboratories concentrate their efforts on the development of high repetition rate FEL-based next generation light sources. One particular concept under development at STFC Daresbury Laboratory specifies high brightness electron bunches with a charge of 0.2 nC which arrive with a repetition rate of up to 1 MHz. As emittance of the bunches should not exceed 1 mm·mrad, traditional grid modulated thermionic injectors, similar to the ones used at ELBE or FELIX, may not be used. We consider three options of high repetition rate injectors based on photocathode guns - a high voltage DC gun, a 3½-cell superconducting RF gun and a normal conducting VHF gun, recently proposed at LBNL. We analyse practical injector schemes for all three guns and provide the results of beam dynamic simulations. We also discuss the photocathodes which may be used in each gun, as this critical component defines achievable beam parameters and operational efficiency of the injectors.
