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…

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…

U-Net-based surrogate modeling for attosecond X-ray free-electron lasers
Yufei Wei, Bingyang Yan, Chenzhi Xu +2
Attosecond X-ray pulse generation in modern X-ray free-electron lasers relies on strongly compressed, precisely tailored electron bunches, making accurate diagnostics and control o…
