Abstract
| We have produced hard x-ray free-electron laser (FEL) pulses, which are chirped both in photon energy and in
spatial position. The experiments have been carried out at the hard x-ray beamline Aramis at SwissFEL, located
at the Paul Scherrer Institute in Switzerland. The FEL beamline was operated without any external focusing
and with a tilted, energy-chirped electron bunch, whose properties are then transferred to the photon beam.
The resulting FEL pulses were used for a single-shot absorption x-ray spectroscopy experiment at the Alvra
endstation. But, as will be outlined, applications of this type of tailored FEL pulse go beyond such experiments,
allowing for x-ray pulse compression and control of the transverse coherence within the pulse |
