ELI-Beamlines (ELI-BL), one of the three pillars Extreme Light Infrastructure endeavour, will be in a unique position to perform research high-energy-density-physics (HEDP), plasma physics and ultra-high intensity (UHI) (1022W/cm2) laser–plasma interaction. Recently need for HED laboratory was identified P3 (plasma platform) installation under construction ELI-BL an answer. The 10 PW laser makes possible fundamental topics from high-field new extreme states matter such as radiation-dominated...
This work studied the pre-plasma that builds up in interactions of focused high-power PW-class lasers with solid targets at target surface facing laser beam, and its impact on global absorption efficiency as well spectral cut-off energy laser-generated proton beams. Our practical heuristic estimates were derived from example VEGA-3 CLPU. modeling results for expansion due to pedestal benchmarked by hydrodynamic simulations, revealing good agreement evolution before arrival main Gaussian...
The Centro de Laseres Pulsados in Salamanca, Spain has recently started operation phase and the first user access period on 6 J 30 fs 200 TW system (VEGA 2) already at beginning of 2018. In this paper we report two commissioning experiments performed VEGA 2 preparation for campaign. been tested different configurations depending focusing optics targets used. One configuration (long focal length $F=130$ cm) is underdense laser–matter interaction where focused onto a low density gas-jet...
This work demonstrates experimentally the close relation between return currents from relativistic laser-driven target polarization and quality of laser–plasma interaction for secondary sources, taking as an example ion acceleration by normal sheath acceleration. The Pearson linear correlation maximum current amplitude proton spectrum cutoff energy is found to be in range ∼0.70 0.94. kA-scale rise all schemes where targets any kind are charged escaping laser-accelerated electrons. Their...
The polysaccharide capsule of Streptococcus pneumoniae is the main virulence factor, which makes bacterium resistant to phagocytosis. Expression capsular must be adjusted at different stages pneumococcal infection, thus, their transcriptional regulation appears crucial. To get insight into existence regulatory mechanisms common most serotypes, a bioinformatic analysis DNA region located upstream locus was performed. With exception serotype 37, between dexB and aliA on chromosome. Up 26...
In this paper, we report on room temperature detection of terahertz radiation from strained-Si modulation-doped field-effect transistors. A non-resonant signal was observed with a maximum around the threshold voltage. The interpreted due to plasma wave nonlinearities in channel. intensity increases for higher applied drain-to-source current. We also dependence polarization incoming radiations.
Abstract Most advanced medical imaging techniques, such as positron-emission tomography (PET), require tracers that are produced in conventional particle accelerators. This paper focuses on the evaluation of a potential alternative technology based laser-driven ion acceleration for production radioisotopes PET imaging. We report first time use high-repetition rate, ultra-intense laser system carbon-11 multi-shot operation. Proton bunches with energies up to 10–14 MeV were systematically...
Abstract We introduce a versatile high-repetition-rate solid tape target system suitable for relativistic laser-plasma driven secondary sources. demonstrate the operation and stability monitoring based on petawatt laser focused at 1 Hz. Experiments were carried out VEGA-3 of Centro de Láseres Pulsados facility where results different materials thicknesses are presented. Experimental proton spectra recorded by Thomson parabola spectrometer time-of-flight detector. In addition, non-invasive...
The 30 and 44 GHz Back End Modules (BEM) for the Planck Low Frequency Instrument are broadband receivers (20% relative bandwidth) working at room temperature. signals coming from Front Module amplified, band pass filtered finally converted to DC by a detector diode. Each receiver has two identical branches following differential scheme of radiometers. BEM design is based on MMIC Noise Amplifiers using GaAs P-HEMT devices, microstrip filters Schottky diode detectors. Their manufacturing...
In this paper, we performed time domain terahertz spectroscopy (THz- TDS) of two drugs (Paracetamol and Ibuprofen). The THz- TDS is based on a Ti:Sapphire femtosecond laser low-temperature grown GaAs photoconductive antennas for emission detection radiation. A working window from 0.2 to 2.5 THz was obtained. First, spectral response water vapor absorption reported compared HITRAN database. good agreement observed. Finally, the spectra commercial (paracetamol ibuprofen) were peaks Different...
The goal of this paper is to study attitude stability in schizophrenics' relatives, as reflected the expressed emotion (EE) construct. For purpose, EE 32 families schizophrenic patients was assessed by means Camberwell Family Interview (CFI, Brown, Birley, & Wing, 1972; Vaughn Leff, 1976b), both initially and at a 9-month follow-up. results obtained indicate that stable fathers, whereas mothers, high seems be influenced stressful situations, because, when crisis, not stable, but...

Abstract Blast waves have been produced in solid target by irradiation with short-pulse high-intensity lasers. The mechanism of production relies on energy deposition from the hot electrons laser–matter interaction, producing a steep temperature gradient inside target. Hot also produce preheating material ahead blast wave and expansion rear side, which results complex propagation dynamic. Several diagnostics used to characterize electron source, induced velocity wave. Results are compared...
