The SwissFEL X-ray Free Electron Laser (XFEL) facility started construction at the Paul
Scherrer Institute (Villigen, Switzerland) in 2013 and will be ready to accept its first users in …

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 …

A collaboration between DESY, PSI and CERN has developed and built an advanced
modular X-band transverse deflection structure (TDS) system with the new feature of …

The SwissFEL soft X-ray free-electron laser (FEL) beamline Athos will be ready for user
operation in 2021. Its design includes a novel layout of alternating magnetic chicanes and …

We demonstrate the generation of widely tunable two-color x-ray free-electron laser (FEL)
pulses at SwissFEL. In a split-undulator configuration, each color is produced in a different …

We present the main specifications of the newly constructed Swiss Free Electron Laser,
SwissFEL, and explore its potential impact on ultrafast science. In light of recent …

Abstract At the Paul Scherrer Institute, two electron accelerator-based photon sources are in
operation, namely a synchrotron source, the swiss light source (SLS), and an X-ray free …

We demonstrate the operation of a compact x-ray free-electron laser (FEL) using the optical
klystron mechanism. This effect speeds up the FEL process using the dispersion of magnetic …

X-ray free-electron lasers (FELs) are modern research tools with applications in multiple
scientific fields. Standard x-ray FEL pulses are produced by the self-amplified spontaneous …

SwissFEL is a compact, high-brilliance, soft and hard X-ray free electron laser (FEL) facility
that started user operation in 2019. The facility is composed of two parallel beam lines …
