Spatiotemporal shaping of attosecond X-rays with time-dependent orbital angular momentum
Chenzhi Xu, Jiawei Yan, Gianluca Geloni +2
Attosecond X-ray pulses are indispensable for exploring ultrafast phenomena in matter on Angstrom and attosecond scales. Here we propose a new method to realize spatiotemporal shap…
Generation of high-power attosecond x-ray FEL pulses carrying orbital angular momentum
Chenzhi Xu, Jiawei Yan, Gianluca Geloni +2
X-ray beams carrying orbital angular momentum (OAM), are emerging as a powerful tool to probe matter. Recently, a method called self-seeded FEL with OAM (SSOAM) has been proposed t…
AttoSHINE: Generation of continuous-wave terawatt-scale attosecond X-ray pulses at SHINE
Bingyang Yan, Chenzhi Xu, Si Chen +4
Attosecond X-ray pulses are a critical tool for tracking ultrafast electron dynamics in condensed matter, molecular systems, and strongly correlated materials. Recent breakthroughs…
Multi-beam-energy control unit based on triple bend achromats
Liuyang Wu, Zihan Zhu, Bingyang Yan +2
X-ray free electron lasers (XFELs) are the new generation of particle accelerator-based light sources, capable of producing tunable, high-power X-ray pulses that are increasingly v…
