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…

"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…

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…
