Laser wakefield acceleration (LWFA) has seen great improvements in recent years, demonstrating the ability to generate high-energy, ultrashort electron beams in compact setups.
However, reproducibility remains a major challenge, with beam properties often affected by shot-to-shot fluctuations [1], caused by fluctuations in the laser system, inconsistencies in the plasma density profile, and...

Laser-Plasma Accelerators (LPAs) produce high-quality electron beams with high peak currents and low emittance, making them ideal for compact novel Free Electron Lasers (FELs). However, the large angular divergence and energy spread of these beams pose challenges for efficient beam transport overall FEL performance. This study explores the use of an Active Plasma Lens (APL) as a capture block...

Laser wakefield accelerators (LWFAs) produce electron bunches that are ideal for driving free-electron lasers (FELs), both in seeded and self-amplified spontaneous emission (SASE) configurations, making them candidates for achieving compact plasma-based FEL user facilities with their ultra-high accelerating gradients and small footprints. However, the inherent shot-to-shot fluctuations, large...

The performance of Free Electron Lasers (FELs) strongly depends on the stability, synchronization, and control of the electron beam that drives the lasing process. While Low-Level RF (LLRF) systems are a critical component regulating the amplitude, phase, and frequency of the RF accelerating fields within linac structures, they form part of a broader control system required to ensure overall...
