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…

Probing the Linewidth of the 12.4-keV Solid-State Sc Isomeric Resonance
Peifan Liu, Miriam Gerharz, Berit Marx-Glowna +37
The Sc nuclear transition from the ground to the isomeric state at 12.389~keV, with a lifetime of 0.46~s, exhibits an extraordinarily narrow natural width of 1.4~feV and a q…
