Covariance Analysis of Impulsive Streaking
Jun Wang, Zhaoheng Guo, Erik Isele +4
We present a comprehensive framework of modeling covariance in angular streaking experiments. Within the impulsive streaking regime, the displacement of electron momentum distribut…
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…
Experimental generation of extreme electron beams for advanced accelerator applications
Claudio Emma, Nathan Majernik, Kelly Swanson +13
In this Letter we report on the experimental generation of high energy (10 GeV), ultra-short (fs-duration), ultra-high current (0.1 MA), petawatt peak power electron beams in a par…
Attosecond Inner-Shell Lasing at Angstrom Wavelengths
Thomas M. Linker, Aliaksei Halavanau, Thomas Kroll +34
Since the invention of the laser nonlinear effects such as filamentation, Rabi-cycling and collective emission have been explored in the optical regime leading to a wide range of s…
Design and Performance of a Magnetic Bottle Electron Spectrometer for High-Energy Photoelectron Spectroscopy
Kurtis Borne, Jordan T ONeal, Jun Wang +19
We describe the design and performance of a magnetic bottle electron spectrometer~(MBES) for high-energy electron spectroscopy. Our design features a ~m long electron drif…
"Beam `a la carte": laser heater shaping for attosecond pulses in a multiplexed x-ray free-electron laser
Siqi Li, Zhen Zhang, Shawn Alverson +19
Electron beam shaping allows the control of the temporal properties of x-ray free-electron laser pulses from femtosecond to attosecond timescales. Here we demonstrate the use of a…
Spectrotemporal shaping of attosecond x-ray pulses with a fresh-slice free-electron laser
River R. Robles, Kirk A. Larsen, David Cesar +14
We propose a scheme allowing coherent shaping, i.e., controlling both the amplitude and phase, of attosecond x-ray pulses at free-electron lasers. We show that by seeding an FEL wi…
Three-dimensional theory of superradiant free-electron lasers
River R. Robles, Luca Giannessi, Agostino Marinelli
The soliton-like superradiant regime of free-electron lasers (FEL) offers a promising path towards ultrashort pulses, beyond the natural limit dictated by the bandwidth of the high…
Attosecond Delays in X-ray Molecular Ionization
Taran Driver, Miles Mountney, Jun Wang +34
The photoelectric effect is not truly instantaneous, but exhibits attosecond delays that can reveal complex molecular dynamics. Sub-femtosecond duration light pulses provide the re…
Attosecond X-ray Core-level Chronoscopy of Aromatic Molecules
Jia-Bao Ji, Zhaoheng Guo, Taran Driver +32
Attosecond photoemission or photoionization delays are a unique probe of the structure and the electronic dynamics of matter. However, spectral congestion and spatial delocalizatio…
Wavelength scaling and multi-color operation of a plasma driven attosecond X-ray source via harmonic generation
Rafi Hessami, Jenny Morgan, River Robles +3
The generation of high power coherent soft X-ray pulses of sub-100 as duration and 10 nm wavelength using beams from a GeV energy plasma wakefield accelerator has been recently inv…
