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

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. [...]

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. [...]

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.

The PSI positron production project

The PSI Positron Production experiment, known as $\text{P}^{3}$ or $\textit{P-cubed}$, is a proof-of-principle positron source and capture system that can greatly improve the state-of-the-art positron yield. The $\text{P}^{3}$ project is led by the Paul Scherrer Institute in Switzerland, and addresses the long-standing challenge faced by conventional injector facilities to generate, capture, and damp the emittance of high-current positron beam, which is a major limiting factor for the feasibility of future electron-positron colliders.
