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. [...]

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. [...]

The FCCee Pre-Injector Complex

The international FCC study group published in 2019 a Conceptual Design Report for an electron-positron collider with a centre-of-mass energy from 90 to 365 GeV with a beam currents of up to 1.4 A per beam. The high beam current of this collider create challenging requirements on the injection chain and all aspects of the linac need to be carefully reconsidered and revisited, including the injection time structure.

The PolariX-TDS Project: Bead-Pull Measurements and High-Power Test on the Prototype
/ Craievich, Paolo (PSI, Villigen) ; Aßmann, Ralph (DESY) ; Bopp, Markus (PSI, Villigen) ; Braun, Hans-Heinrich (PSI, Villigen) ; Catalán Lasheras, Nuria (CERN) ; Christie, Florian (DESY) ; Citterio, Alessandro (PSI, Villigen) ; D'Arcy, Richard (DESY) ; Dorda, Ulrich (DESY) ; Foese, Manon (DESY) et al.
A collaboration between DESY, PSI and CERN has been established to develop and build an advanced modular X- band transverse deflection structure (TDS) system with the new feature of providing variable polarization of the deflecting force. The prototype of the novel X-band TDS, the Polarizable X-band (PolariX) TDS, was fabricated at PSI following the high-precision tuning-free production process developed for the C-band Linac of the SwissFEL project.

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.

Design of a Terahertz Radiation Source for Pump-Probe Experiments
/ Pfingstner, Juergen (Oslo U.) ; Adli, Erik (Oslo U.) ; Marín, Eduardo (CERN) ; Reiche, Sven (PSI, Villigen)
Narrow-band, tuneable, high-power terahertz radiation is highly demanded for pump-probe experiments at light source facilities. Since the requested radiation properties are not well covered by current terahertz radiation sources, an accelerator-based terahertz source employing the slotted-foil technique in combination with transverse deflecting cavities is proposed in this work.

A collaboration between DESY, PSI and CERN has been established to develop and build an advanced modular X-band transverse deflection structure (TDS) system with the new feature of providing variable polarization of the deflecting force. This innovative CERN design requires very high manufacturing precision to guarantee highest azimuthal symmetry of the structure to avoid the deterioration of the polarization of the streaking field.
