During the last fifty years, nonneutral plasma physics has developed into a definite subfield
of basic research, whose main focus has been on the collective properties of systems …

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 …

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 …

Multibend magnetic bunch compressors are commonly used to produce beams with high
peak current in modern accelerators that call for high-brightness beams. If not well …

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 …

A confined electron laser is a “wiggled” electron beam confined by the ponderomotive forces
inside an electromagnetic cavity. The ponderomotive forces counteract the beam expansion …

Modern science advancements rely on the possibility of producing short laser-like coherent
pulses in the XUV and in the X-rays wavelength ranges to probe electronic structure in …

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 …

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 …
