Abstract Very-high-frequency (VHF) gun photoinjectors, capable of producing high-
brightness and high-repetition-rate electron bunches, are some of the best electron sources …

Active longitudinal beam optics can help free-electron laser facilities achieve cutting edge
performance by optimizing the beam to produce multicolor pulses, suppress caustics, or …

Beam-driven collinear wakefield accelerators (CWAs) that operate by using slow-wave
structures or plasmas hold great promise toward reducing the size of contemporary …

The formation of a double-horn current profile is a challenging issue in the achievement of
electron bunch with high peak current, especially for high-repetition-rate X-ray free-electron …

Control of coherent synchrotron radiation (CSR)-induced emittance growth is essential in
linear accelerators designed to deliver very high brightness electron beams. Extreme current …

A bstract We discuss singularity variables which are properly suited for analyzing the
kinematics of events with missing transverse energy at the LHC. We consider six of the …

Synchronizing free-electron laser pulses for time-resolved experiments is necessary as an
unsynchronized system reduces the effective repetition rate of the experiment. Additionally …

High brightness electron beams are critical for x-ray free-electron laser performance. To
achieve higher peak current, strong longitudinal compression often produces electron …

At the time this thesis is written, the world nds itself amidst and partly in the process of
recovering from the COVID-19 pandemic caused by the SARS-Cov-2 virus. One major …

The MAX IV Laboratory is a synchrotron radiation user facility located just outside the city of
Lund, Sweden. The facility is made up of two storage rings, at 3 GeV and 1.5 GeV …
