We present an initial feasibility summary of a femtosecond synchrotron radiation x-ray source based on a flat-beam rf gun and a recirculating superconducting linac that provides beam to an array of undulators and bend magnets. Optical pulse durations of <100 fs are obtained by a combination of electron pulse compression, transverse temporal correlation of the electrons, and x-ray pulse compress...

RF photoinjectors have been under development for several decades to provide the high-brightness electron beams required X-ray Free Electron Lasers. This paper proposes a photoinjector design that meets Horizon 2020 CompactLight study requirements. It consists of 5.6-cell, X-band (12 GHz) gun, an emittance-compensating solenoid and two traveling-wave structures accelerate beam out space-charge-...

The high spatial resolution needed in self-consistent particle simulations can be achieved using adaptive mesh refinement techniques (AMR). In this paper the code SMOVE which is based on such an adaptive mesh is presented. It allows for accurate simulations with a high spatial resolution in the vicinity of the particle bunches. Furthermore, it offers the possibility of simulating long accelerat...
