Using the optical-klystron effect to increase and measure the intrinsic beam energy spread in free-electron-laser facilities

Eugenio Ferrari, Thomas Schietinger, Sven Reiche

We present a setup based on the optical klystron concept, consisting of two undulator modules separated by a magnetic chicane, that addresses two issues in free-electron-laser (FEL) facilities. On the one hand, it allows increasing the intrinsic energy spr ...
