Coherent sub-femtosecond soft x-ray free-electron laser pulses with nonlinear compression
/ Prat, Eduard (PSI, Villigen) ; Malyzhenkov, Alexander (CERN) ; Arrell, Christopher (PSI, Villigen) ; Craievich, Paolo (PSI, Villigen) ; Reiche, Sven (PSI, Villigen) ; Schietinger, Thomas (PSI, Villigen) ; Wang, Guanglei (PSI, Villigen)
We demonstrate the generation of coherent soft x-ray free-electron laser (FEL) pulses with a duration below 1 fs using nonlinear compression with a low-charge electron beam (10 pC). The approach is simple, and it does not require any special hardware, so it can be readily implemented at any x-ray FEL facility. [...]

An X-ray free-electron laser with a highly configurable undulator and integrated chicanes for tailored pulse properties

X-ray free-electron lasers (FELs) are state-of-the-art scientific tools capable to study matter on the scale of atomic processes. Since the initial operation of X-ray FELs more than a decade ago, several facilities with upgraded performance have been put in operation. [...]

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 [...]

SwissFEL Aramis beamline photon diagnostics
/ Juranic, Pavle (PSI, Villigen) ; Rehanek, Jens (PSI, Villigen) ; Arrell, Christopher A (PSI, Villigen) ; Pradervand, Claude (PSI, Villigen) ; Cassar, Ariana (U. Malta) ; Calvi, Marco (PSI, Villigen) ; Ischebeck, Rasmus (PSI, Villigen) ; Erny, Christian (PSI, Villigen) ; Heimgartner, Peter (PSI, Villigen) ; Gorgisyan, Ishkhan (CERN) et al.
The SwissFEL Aramis beamline, covering the photon energies between
1.77 keV and 12.7 keV, features a suite of online photon diagnostics tools
to help both users and FEL operators in analysing data and optimizing
experimental and beamline performance. Scientists will be able to obtain
information about the flux, spectrum, position, pulse length, and arrival time
jitter versus the experimental laser for every photon pulse, with further
information about beam shape and size available through the use of destructive
screens. [...]

Sub-Femtosecond Time-Resolved Measurements Based on a Variable Polarization X-Band Transverse Deflecting Structures for SwissFEL
/ Craievich, Paolo (PSI, Villigen) ; Aßmann, Ralph (DESY) ; Bopp, Markus (PSI, Villigen) ; Braun, Hans-Heinrich (PSI, Villigen) ; Catalán Lasheras, Nuria (CERN) ; Christie, Florian (DESY) ; D'Arcy, Richard (DESY) ; Ganter, Romain (PSI, Villigen) ; Grudiev, Alexej (CERN) ; Marchetti, Barbara (DESY) et al.
The SwissFEL project, under commissioning at the Paul Scherrer Institut (PSI), will produce FEL radiation for soft and hard X-rays with pulse durations ranging from a few to several tens of femtoseconds. A collaboration between DESY, PSI and CERN has been established with the aim of developing and building an advanced X-Band transverse deflector structure (TDS) with the new feature of providing variable polarization of the deflecting force.

Attosecond x-ray pulses in the LCLS using the slotted foil method
/ Emma, P ; Borland, M ; Huang, Z
A proposal has been made to generate femtosecond and sub-femtosecond x-ray pulses in the Linac Coherent Light Source (LCLS) SASE FEL by using a slotted spoiler foil located at the center of the second bunch compressor chicane. This previous study highlighted a simple case, using the nominal LCLS parameters, to produce a 2-fsec fwhm, 8-keV x-ray pulse. [...]
