Target Design for XUV Probing of Radiative Shock Experiments
U. Chaulagain, C. Stehlé, P. Barroso +4
Radiative shocks are strong shocks characterized by plasma at a high temperature emitting an important fraction of its energy as radiation. Radiative shocks are commonly found in m…
Determination of the spectral variation origin in high-order harmonic generation in noble gases
V. E. Nefedova, M. F. Ciappina, O. Finke +7
One key parameter in the high-order harmonic generation (HHG) phenomenon is the exact frequency of the generated harmonic field. Its deviation from perfect harmonics of the laser f…
Experimental study of the interaction of two laser-driven radiative shocks at the PALS laser
R. L. Singh, C. Stehle, F. Suzuki-Vidal +14
Radiative shocks (RS) are complex phenomena which are ubiquitous in astrophysical environments. The study of such hypersonic shocks in the laboratory, under controlled conditions,…
Phase-matched high-order harmonic generation in pre-ionized noble gases
O. Finke, J. Vábek, M. Nevrkla +8
One of the main difficulties to efficiently generating high-order harmonics in long neutral-gas targets is to reach the phase-matching conditions. One issue is that the medium cann…
Development of LPA based hard X-ray sources at ELI Beamlines
U. Chaulagain, M. Lamac, M. Raclavsky +4
We report the laser-plasma accelerator-based X-ray sources development at ELI beamlines. One of the main objectives of ELI Beamlines is to provide beams of ultrashort particle and…
Sampling requirements in near-field ptychography
L. Fardin, Y. Pulnova, T. Parkman +10
Ptychography is a robust lensless form of microscopy routinely used for applications spanning life and physical sciences. The most common ptychography setup consists in using a det…
Demonstration of The Brightest Nano-size Gamma Source
A. S. Pirozhkov, A. Sagisaka, K. Ogura +46
Gamma rays selectively interact with nuclei, induce and mediate nuclear reactions and elementary particle interactions, and exceed x-rays in penetrating power and thus are indispen…
Long-lasting XUV activation of helium nanodroplets for avalanche ionization
C. Medina, A. Ã. Lægdsmand, L. Ben Ltaief +13
We study the dynamics of avalanche ionization of pure helium nanodroplets activated by a weak extreme-ultraviolet (XUV) pulse and driven by an intense near-infrared (NIR) pulse. In…
Ultrafast hard X-ray sources based on Relativistic Electrons at ELI Beamlines
U. Chaulagain, M. LamaÄ, M. Raclavský +3
We report the LWFA driven X-ray sources development at ELI beamlines. ELI Gammatron beamline provides X-ray pulses of energies from 1-100 keV in betatron scheme, and up to a MeV in…
