Time-resolved optical shadowgraphy of solid hydrogen jets as a testbed to benchmark particle-in-cell simulations
Long Yang, Lingen Huang, Stefan Assenbaum +11
Particle-in-cell (PIC) simulations are a superior tool to model kinetics-dominated plasmas in relativistic and ultrarelativistic laser-solid interactions (dimensionless vectorpoten…
Visualizing Plasmons and Ultrafast Kinetic Instabilities in Laser-Driven Solids using X-ray Scattering
Paweł Ordyna, Carsten Bähtz, Erik Brambrink +27
Ultra-intense lasers that ionize and accelerate electrons in solids to near the speed of light can lead to kinetic instabilities that alter the laser absorption and subsequent elec…
Probing the dynamics of solid density micro-wire targets after ultra-intense laser irradiation using a free-electron laser
Thomas Kluge, Michael Bussmann, Eric Galtier +22
In this paper, we present an experiment that explores the plasma dynamics of a 7 micron diameter carbon wire after being irradiated with a near-relativistic-intensity short pulse l…
Heating in Multi-Layer Targets at ultra-high Intensity Laser Irradiation and the Impact of Density Oscillation
Franziska-Luise Paschke-Bruehl, Mohammad Banjafar, Marco Garten +7
We present a computational study of isochoric heating in multi-layered targets at ultra-high intensity laser irradiation (approx. 10**20 W/cm**2). Previous studies have shown enhan…
Optimized laser ion acceleration at the relativistic critical density surface
Ilja Göthel, Constantin Bernert, Michael Bussmann +8
In the effort of achieving high-energetic ion beams from the interaction of ultrashort laser pulses with a plasma, volumetric acceleration mechanisms beyond Target Normal Sheath Ac…
Compact Spectroscopy of keV to MeV X-rays from a Laser Wakefield Accelerator
A. Hannasch, A. Laso Garcia, M. LaBerge +12
We reconstruct spectra of secondary X-rays from a tunable 250-350 MeV laser wakefield electron accelerator from single-shot X-ray depth-energy measurements in a compact (7.5 $\time…
Probing ultrafast laser plasma processes inside solids with resonant small-angle X-ray scattering
Lennart Gaus, Lothar Bischoff, Michael Bussmann +33
Extreme states of matter exist throughout the universe e.g. inside planetary cores, stars or astrophysical jets. Such conditions are generated in the laboratory in the interaction…
Radiative characterization of supersonic jets and shocks in a laser-plasma experiment
H Bohlin, F-E Brack, M Cervenak +21
The interaction of supersonic laser-generated plasma jets with a secondary gas target was studied experimentally. The plasma parameters of the jet, and the resulting shock, were ch…
Laser-plasma proton acceleration with a combined gas-foil target
Dan Levy, Constantin Bernert, Martin Rehwald +10
Laser-plasma proton acceleration was investigated in the Target Normal Sheath Acceleration (TNSA) regime using a novel gas-foil target. The target is designed for reaching higher l…
Proton beam quality enhancement by spectral phase control of a PW-class laser system
T. Ziegler, D. Albach, C. Bernert +24
We report on experimental investigations of proton acceleration from solid foils irradiated with PW-class laser-pulses, where highest proton cut-off energies were achieved for temp…
First demonstration of multi-MeV proton acceleration from a cryogenic hydrogen ribbon target
Stephan D. Kraft, Lieselotte Obst, Josefine Metzkes-Ng +9
We show efficient laser driven proton acceleration up to 14MeV from a 50 m thick cryogenic hydrogen ribbon. Pulses of the short pulse laser ELFIE at LULI with a pulse length of…
I-BEAT: New ultrasonic method for single bunch measurement of ion energy distribution
Daniel Haffa, Rong Yang, Jianhui Bin +31
The shape of a wave carries all information about the spatial and temporal structure of its source, given that the medium and its properties are known. Most modern imaging methods…
