Linear accelerators delivering high brightness electron beams are essential for a number of
current and proposed accelerator applications, such as free electron lasers (FELs). In this …

Coherent synchrotron radiation (CSR) is of great interest to those designing accelerators as
drivers for free-electron lasers (FELs). Although experimental evidence is incomplete, CSR …

In this article we study the effect of radiative interaction in a microbunch of charged particles
following a curved trajectory. Due to the curvature, the cooperative electromagnetic fields …

Minimizing transverse emittance is essential in linear accelerators designed to deliver very
high brightness electron beams. Emission of coherent synchrotron radiation (CSR), as a …

Practically all synchrotron x-ray sources to data are based on the use of storage rings to
produce the high current electron (or positron) beams needed for synchrotron radiation (SR) …

For the simulation of high-brightness electron bunches, a new 3D space-charge model is
being implemented in the General Particle Tracer (GPT) code. It is based on a non …

The parallel operation of plural undulator beam lines is an important means of improving the
efficiency and usability of x-ray free-electron laser facilities. After the installation of a second …

An understanding of collective effects is of fundamental importance for the design and
optimisation of the performance of modern accelerators. In particular, the design of an …

The transverse emittance of the electron beam is a fundamental parameter in linac-based x-
ray free-electron lasers (FELs). We present results of emittance measurements carried out at …

We have produced hard x-ray free-electron laser (FEL) radiation with unprecedented large
bandwidth tunable up to 2%. The experiments have been carried out at SwissFEL, the x-ray …
