Circular polarization control for the LCLS baseline in the soft X-ray regime
Gianluca Geloni, Vitali Kocharyan, Evgeni Saldin
The LCLS baseline includes a planar undulator system, producing linearly polarized light in the range 0.15-1.5 nm. Polarization control in the soft X-ray region from linear to circ…
Self-seeded operation of the LCLS hard X-ray FEL in the long-bunch mode
Gianluca Geloni, Vitali Kocharyan, Evgeni Saldin
Self-seeding options for the LCLS baseline were recently investigated using a scheme which relies on a single-crystal monochromator in Bragg-transmission geometry. The LCLS low-cha…
Generation of doublet spectral lines at self-seeded X-ray FELs
Gianluca Geloni, Vitali Kocharyan, Evgeni Saldin
Self-seeding schemes, consisting of two undulators with a monochromator in between, aim to reduce the bandwidth of SASE X-ray FELs. We recently proposed a new method of monochromat…
Way to increase the user access at the LCLS baseline
Gianluca Geloni, Vitali Kocharyan, Evgeni Saldin
The LCLS beam is meant for a single user, but the baseline undulator is long enough to serve two users simultaneously. To this end, we propose a setup composed of two elements: an…
Cost-effective way to enhance the capabilities of the LCLS baseline
Gianluca Geloni, Vitali Kocharyan, Evgeni Saldin
This paper discusses the potential for enhancing the LCLS hard X-ray FEL capabilities. In the hard X-ray regime, a high longitudinal coherence will be the key to such performance u…
Scheme for generation of fully-coherent, TW power level hard X-ray pulses from baseline undulators at the European X-ray FEL
Gianluca Geloni, Vitali Kocharyan, Evgeni Saldin
The most promising way to increase the output power of an X-ray FEL (XFEL) is by tapering the magnetic field of the undulator. Also, significant increase in power is achievable by…
