Sub-femtosecond time-resolved measurements of electron bunches with a C-band radio-frequency deflector in x-ray free-electron lasers / Prat, Eduard (PSI, Villigen) ; Malyzhenkov, Alexander (CERN) ; Craievich, Paolo (PSI, Villigen)
Time-resolved diagnostics are fundamental for x-ray free-electron lasers (FELs). Radio-frequency (RF) transverse deflector structures (TDSs) are typically employed to characterize the temporal properties of the electron beams driving FELs. [...]

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. [...]

Frequency and spatially chirped free-electron laser pulses / Reiche, S (PSI, Villigen) ; Bacellar, C (PSI, Villigen) ; Bougiatioti, P (PSI, Villigen) ; Cirelli, C (PSI, Villigen) ; Dijkstal, P (PSI, Villigen ; DESY) ; Ferrari, E (PSI, Villigen ; DESY) ; Juranic, P (PSI, Villigen) ; Knopp, G ; Malyzhenkov, 2A (PSI, Villigen ; CERN) ; Milne, C (PSI, Villigen ; European XFEL, Hamburg) et al.
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 [...]

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. [...]

Technique for the Generation of Attosecond X-Ray Pulses Using an FEL / Penn, Gregory ; Zholents, Alexander
We describe a technique for the generation of an isolated burst of X-ray radiation with a duration of ~100 attoseconds in a free electron laser (FEL) employing self-amplified spontaneous emission. Our scheme relies on an initial interaction of the electron beam with an ultra-short laser pulse in a one-period wiggler followed by compression in a dispersive section. [...]
