The first generation of S-band injectors for free-electron lasers has illustrated high reliability
and performance by driving the latest generation of high brightness machines. However, the …

We present high-resolution measurements of the electron beam energy spread at the
SwissFEL injector as a function of the electron bunch charge, the optics, and the longitudinal …

The intrinsic energy spread of electron beams needs to be measured to characterize and
optimize high-brightness electron beam sources such as those driving x-ray free-electron …

We present theoretical analysis and design considerations of a THz superradiant FEL. We
derive analytical expressions for the spectral parameter of THz radiation, emitted …

Transverse profile monitors are essential devices to characterize particle beams in
accelerators. Here, we present an improved design of beam profile monitors at SwissFEL …

Recent studies have identified intra-beam scattering (IBS) as one of the processes that can
have a significant impact on the beam dynamics of linacs with high-density and low-energy …

Methodical studies to improve the existing e-beam Longitudinal Phase Space (LPS)
tomography were performed at the Photo Injector Test facility at DESY in Zeuthen. Proof-of …

Due to improvements of the performance of FELs, the measurements of the beam's slice
energy spread is becoming increasingly important for optimization of the brightness. Of …

Optimising the slice energy spread in X-ray free electron lasers (XFELs) is key to their
effective operation, and must be considered from the photoinjector at the very beginning of …

Recent studies have identified intrabeam scattering (IBS) as one of the processes that can
have a significant impact on the beam dynamics of linacs with high-density and lowenergy …
