Femtosecond electron and x-ray source based on laser wakefield accelerator
Dmitri A. Oulianov, Yuelin Li, Robert A. Crowell +4
A terawatt tabletop laser wakefield acceleration source of relativistic electrons has been developed in our Terawatt Ultrafast High Field Facility (TUHFF). The preliminary results…
Ultrafast Pulse Radiolysis Using a Terawatt Laser Wakefield Accelerator
Dmitri A. Oulianov, Robert A. Crowell, David J. Gosztola +3
We report the first ultrafast pulse radiolysis transient absorption spectroscopy measurements from the Terawatt Ultrafast High Field Facility (TUHFF) at Argonne National Laboratory…
Electron Photodetachment from Aqueous Anions. III. Dynamics of Geminate Pairs Derived from Photoexcitation of Mono- vs. Poly- atomic Anions
Rui Lian, Dmitri A. Oulianov, Robert A. Crowell +3
Photostimulated electron detachment from aqueous inorganic anions is the simplest example of solvent-mediated electron transfer. Here we contrast the behavior of halide anions with…
Geminate recombination of electrons generated by above-the-gap (12.4 eV) photoionization of liquid water
Rui Lian, Dmitri A. Oulianov, Ilya A. Shkrob +1
The picosecond geminate recombination kinetics for hydrated electrons generated by 200 nm two photon absorption (12.4 eV total energy) has been measured in both light and heavy wat…
Frequency-domain "single-shot" (FDSS) transient absorption spectroscopy using a variable-length grating pair compressor
Ilya A. Shkrob, Dmitri A. Oulianov, Robert A. Crowell
Single-shot ultrafast spectroscopy based on the frequency encoding of transient absorbance kinetics (FDSS) is demonstrated. These kinetics are sampled spectrally using linearly chi…
Light-induced temperature jump causes power-dependent ultrafast kinetics of electrons generated in multiphoton ionization of liquid water
Robert A. Crowell, Rui Lian, Ilya A. Shkrob +3
Picosecond geminate recombination kinetics for electrons generated by multiphoton ionization of liquid water become power dependent when the radiance of the excitation light is gre…
