SASE-FEL: Session-3
- Gianluca Geloni (European XFEL GmbH)
LCLS-2 is the first FEL operating in CW mode. During the first stage commissioning including injector, linac and FEL, we successfully achieved the initial goal in the summer of 2023, with operating the beam in the linac at 93kHz, and demonstrated FEL at 1kHz. Since then, operation-based commissioning for performance improvement has started. We will present the latest commissioning progress,...
The FLASH2020+ project is driving the current transformation of the FLASH facility. The next step is the transition of FLASH1 from a SASE to a high repetition rate externally seeded FEL beamline and will significantly expand the facilities capabilities. The generation of near transform limited pulses at superior spectral and pulse energy stability at full FLASH repetition rate of 1 MHz burst...
Wakefield structures using metallic corrugated plates have demonstrated their capabilities in high-energy electron beam manipulation and diagnostics at low repetition-rate X-ray free-electron laser (XFEL) facilities. There has been a significant effort recently to utilize such devices at a MHz repetition rate. Here we first give an overview of the theoretical modeling and experimental...
Despite significant advancements in generating attosecond pulses in the extreme ultraviolet and soft X-ray regimes, achieving high-power attosecond pulses at Ångstrom wavelengths has remained a considerable challenge. The generation of intense attosecond hard X-ray pulses is pivotal for probing the structural and electronic dynamics of matter with unprecedented precision. Recently, we proposed...
