Upstream Laser-based Longitudinal Enhancement of Relativistic Photoelectrons
Hao Zhang, Randy Lemons, Jack Hirschman +23
Controlling the longitudinal phase space of high-brightness relativistic electron beams is crucial for advancing a broad spectrum of charged-particle-based instrumentation and scie…
Beam Halo Formation via Longitudinal-Transverse Coupling in Continuous-Wave Photoinjectors
Zhen Zhang, Yuantao Ding, David Cesar +3
Beam halo formation poses a critical challenge for high-repetition-rate continuous-wave (CW) free-electron lasers (FELs), directly affecting beam quality and machine protection, as…
Nonlinear reversal of photo-excitation on the attosecond time scale improves ultrafast x-ray diffraction images
Anatoli Ulmer, Phay J. Ho, Bruno Langbehn +28
The advent of isolated and intense sub-femtosecond X-ray pulses enables tracking of quantummechanical motion of electrons in molecules and solids. The combination of X-ray spectros…
Experimental demonstration of attosecond hard X-ray pulses
Ichiro Inoue, River Robles, Aliaksei Halavanau +24
We present the first direct experimental confirmation of attosecond pulse generation in the hard X-ray regime with a free-electron laser. Our experiment is based on measurements of…
Attosecond Coherent Electron Motion in a Photoionized Aromatic Molecule
Taran Driver, Zhaoheng Guo, Erik Isele +50
In molecular systems, the ultrafast motion of electrons initiates the process of chemical change. Tracking this electronic motion across molecules requires coupling attosecond time…
