We have converted the former solar electrical plant THEMIS (French Pyrenees) into an atmospheric Cerenkov detector called CELESTE, which records gamma rays above 30 GeV (7 × 1024 Hz). Here we present first sub-100 detection by a ground-based telescope of gamma-ray source, Crab Nebula, in energy region between satellite measurements and imaging telescopes. At our analysis threshold 60 ± 20 measure rate 6.1 0.8 minute-1. Allowing for 30% systematic uncertainties error on scale yields integral...
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...
Abstract This paper deals with computation of mean speckle size in a pattern generated through numerical simulation after reflection Gaussian beam off rough object’s surface. Within this various patterns are obtained by means change parameter the beam. The is computed two approaches using both two-dimensional and one-dimensional normalized autocorrelation function intensity. Additionally, we propose distinct optimization determination reduction intensity values representing detected...
Abstract The paper describes the possibility of using speckle pattern decorrelation for determination small deformation tensor components an elementary object surface area in optical image field. relationship between small-deformation and field displacement is analysed detail. studied problem presented from approximation viewpoint both wave geometrical optics.
We present the results of studies devoted to development and optimization optical part a high precision time-of-flight (TOF) detector for Large Hadron Collider (LHC). This work was motivated by proposal use such in conjunction with silicon tag measure protons from interactions type p + → X p, where two outgoing are scattered very forward directions. The fast timing uses fused silica (quartz) bars that emit Cherenkov radiation as relativistic particle passes through emitted photons detected...
The paper introduces a modified approach of time resolved in-situ diagnostics highly reactive discharges (C2H2 in our case) usually used for deposition process various non-conductive thin films. Reactive plasma could create an insulating film onto inserted diagnostic tools, which distorts measured data and makes their processing unreliable; typical problem Langmuir probe measurements. proposed utilizes so-called radiofrequency (rf) Sobolewski ion flux measurement is further to also obtain...
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.
