82. Measurement of the energy spectrum of cosmic rays at the highest energies using data from Pierre Auger Observatory

Gonzalo Rodriguez Fernandez (ROMA2)

23/05/2013, 16:45

We report a measurement of the cosmic ray energy spectrum based on the high statistics collected by the surface detector of the Pierre Auger Observatory. Based on the combination of fluorescence detector (FD) and surface detector (SD) and do not rely on detailed numerical simulation or any assumption about the chemical composition. The energy calibration of the observables, which exploits the...

51. Proof of feasibility of the Vacuum Silicon PhotoMultiplier Tube (VSiPMT)

Daniele Vivolo (NA)

VSiPMT (Vacuum Silicon PhotoMultiplier Tube) is an innovative hybrid photon detector combining the performances and the potential of SiPM technology with a hemispherical glass PMT standard envelope. Our purpose is to combine the key features of a SiPM (high quantum efficiency, low operation voltages, insensitivity to magnetic fields and robustness) with the large sensitive area of a...

36. SiPM application for a detector for UHE neutrinos tested at Sphinx Station

Mr Ali Yilmaz (Abant Izzet Baysal University 14250, Bolu, Turkey)

23/05/2013, 17:25

We present the preliminary test results of the prototype detector, working at Sphinx Observatory Center, Jungfraujoch ($\sim$3800 m a.s.l.) HFSJG - Switzerland. This prototype detector is designed to measure a large angle cosmic rays flux emerging from the Earth crust. This station provides us an opportunity to understand if the prototype detector works safely under harsh environmental...

83. Multi-TeV Gamma astronomy: The Tunka-HiSCORE project

Ralf Wischnewski (DESY)

23/05/2013, 17:45

The new HiSCORE detector concept is based on Cerenkov air-shower detection, using the non-imaging technique. HiSCORE is build for gamma-ray astronomy from 10 TeV to several PeV, and cosmic rays studies from 100 TeV to 1 EeV. It will search for "pevatrons" (ultra-high energy gamma-ray sources), and measure cosmic ray composition and spectrum in the transition range from a supposed Galactic to...
