Generation of high-fluence and high-intensity hard x-ray attosecond pulses at European XFEL
Ichiro Inoue, Ulrike Boesenberg, Rustam Rysov +41
By combining hard x-ray attosecond pulses from the European XFEL with total-reflection focusing x-ray optics, we generated nanofocused hard x-ray attosecond pulses with intensities…
Beam based undulator trajectory alignment at European XFEL
Winfried Decking, Frank Brinker, Lars Froehlich +2
Precise alignment of the undulator trajectory onto a straight line is a per-requisite for high fidelity SASE operation, which in turn also enables non-standard operation modes like…
Beam-Driven Transverse Deflecting Structure for Femtosecond Electron-Beam Diagnostics
S. Tomin, D. Bazyl, W. Decking +1
High-resolution longitudinal phase-space (LPS) diagnostics are essential for X-ray free-electron lasers and advanced accelerators. Conventional radio-frequency transverse deflectin…
High-power attosecond X-ray free-electron lasers: physics and design strategy
Chenzhi Xu, Jiawei Yan, Ye Chen +5
Attosecond pulses from X-ray free-electron laser (XFEL) have opened new opportunities for probing ultrafast electronic dynamics on the Angstrom--attosecond spatiotemporal scale. Mo…
