Towards Chirp Control of XUV Free Electron Lasers
8th EPS-QEOD EUROPHOTON CONFERENCE, BarcelonaBarcelona, Spain, 2 Sep 2018 - 7 Sep 20182018-09-022018-09-07  GO
We use 267nm femtosecond laser pulses to modulate electrons of a XUV free electron laser. By changing the chirp of this laser pulses we can influence the chirp of the generated XUV FEL pulses, which are characterized by THz streaking. [...]

TESLA-FEL Reports 12 pp. () [10.3204/PUBDB-2018-04128]  GO
In this article we study the effect of radiative interaction in a microbunch of charged particles following a curved trajectory. Due to the curvature, the cooperative electromagnetic fields radiated from back parts of the bunch can overtake the head particles. [...]
