We report a measurement of the energy spectrum cosmic rays above $2.5{\times} 10^{18}$ eV based on $215,030$ events. New results are presented: at about $1.3{\times} 10^{19}$ eV, spectral index changes from $2.51 \pm 0.03 \textrm{ (stat.)} 0.05 (sys.)}$ to $3.05 (stat.)}\pm 0.10\textrm{ (sys.)}$, evolving $5.1\pm0.3\textrm{ 0.1\textrm{ beyond $5{\times} while no significant dependence features declination is seen in accessible range. These can be reproduced models with energy-dependent mass...
ELI-Beamlines will be a high-energy, repetition-rate laser pillar of the ELI (Extreme Light Infrastructure) project. It an international facility for both academic and applied research, slated to provide user capability since beginning 2016. The main objective Project is delivery ultra-short high-energy pulses generation applications high-brightness X-ray sources accelerated particles. system delivering with length ranging between 10 150 fs petawatt 10-PW peak powers. For high-field physics...
The Cherenkov Telescope Array (CTA) is the next generation very high-energy gamma-ray observatory, with at least 10 times higher sensitivity than current instruments. CTA will comprise several tens of Imaging Atmospheric Telescopes (IACTs) operated in array-mode and divided into three size classes: large, medium small telescopes. total reflective surface could be up to 10,000 m<sup>2</sup> requiring unprecedented technological efforts. properties reflector directly influence telescope...
We present a discovery and observation of an extraordinarily bright prompt optical emission the GRB 060117 obtained by wide-field camera atop robotic telescope FRAM Pierre Auger Observatory from 2 to 10 minutes after GRB. found rapid average temporal flux decay alpha = -1.7 +- 0.1 peak brightness R 10.1 mag. Later observations other instruments set strong limit on radio transient fluxes, unveiling unexpectedly further decay. interpretation featuring relatively steep electron-distribution...
The Fluorescence detector Array of Single-pixel Telescopes is a proposed low-cost, large-area, next-generation experiment for the detection ultrahigh-energy cosmic rays via atmospheric fluorescence technique. design involves deployment several hundred large field-of-view telescopes on regular grid thousand square kilometers in ground area. This paper describes optical prototype telescope, as well its mechanical support structure.

The SST-1M project, run by a Consortium of institutes from Czech Republic, Poland and Switzerland, has been proposed as solution for implementing the small-size telescope array southern site Cherenkov Telescope Array. technology is pathfinder efficient production cost-effective imaging air telescopes. We report on main system features recent upgrades, performances validation operation campaign carried out in 2018.
Diffuse and specular characteristics of the Tyvek 1025-BL material are reported with respect to their implementation in Geant4 Monte Carlo simulation toolkit. This toolkit incorporates UNIFIED model. Coefficients defined by model were calculated from bidirectional reflectance distribution function (BRDF) profiles measured a scatterometer for several angles incidence. Results amended profile measurements made profilometer.
