Coherent X-rays with Tunable Time-Dependent Polarization
Nicholas Sudar, Ryan Coffee, Erik Hemsing
We describe a method for producing high power, coherent x-ray pulses from a free electron laser with femtosecond scale periodic temporal modulation of the polarization vector. This…
Enhanced Self-seeding with Ultra-short Electron Beams
Erik Hemsing, Aliaksei Halavanau, Zhen Zhang
We describe a new method to produce intensity stable, highly coherent, narrow-band x-ray pulses in self-seeded free electron (FEL) lasers. The approach uses an ultra-short electron…
Free Electron Laser Generation of X-Ray Poincaré Beams
Jenny Morgan, Erik Hemsing, Brian W. J. McNeil +1
An optics-free method is proposed to generate X-ray radiation with spatially variant states of polarization via an afterburner extension to a Free Electron Laser (FEL). Control of…
