30TH INTERNATIONAL COSMIC RAY CONFERENCE A Measurement of the Average Longitudinal Development Profile of Cosmic Ray Air Showers from 10eV to 10eV by HiRes-II
نویسنده
چکیده
A method to calculate the Average Longitudinal Shower profile has been applied to the High Resolution Fly’s Eye Detector (HiRes) data. A complete detector simulation was used to throw CORSIKA (QGSJET) showers which are then analyzed using the same technique. The main features of the average showers are compared to the Monte Carlo as a function of energy. Systematic errors in the reconstruction of the profile are considered.

A study on the lateral distribution of Cherenkov light in extensive air showers
The dependence of the lateral distribution of Cherenkov light in simulated extensive air showers to the energy and the mass of the primary cosmic rays has been studied. It has been shown that a previous claim about mass independent proportionality of shower energy to the total Cherenkov photon number is not valid in energies below EEAS ~ 1014 eV. We have found that the core distance of the so c...
متن کاملThe Anisotropy of Cosmic Ray Arrival Directions around 10eV
Anisotropy in the arrival directions of cosmic rays with energies above 10eV is studied using data from the Akeno 20 km array and the Akeno Giant Air Shower Array (AGASA), using a total of about 114,000 showers observed over 11 years. In the first harmonic analysis, we have found strong anisotropy of ∼ 4% around 10eV, corresponding to a chance probability of ∼ 0.2% after taking the number of in...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE Shower size spectrum reconstructed with KASCADE-Grande
The Grande array as main part of the KASCADE-Grande experiment consists of 37×10 m scintillation detectors spread over an area of 700×700 m. Grande enables triggers and reconstruction of primary cosmic rays in the energy range of ∼ 3 · 10eV to 10eV. The detectors and the shower size (i.e.: total number of charged particles) reconstruction accuracies are discussed. The KASCADEGrande set-up allow...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE An upper limit on the electron-neutrino flux from the HiRes instrument
Air-fluorescence detectors such as the High Resolution Fly’s Eye (HiRes) instrument are very sensitive to upward-going, Earth-skimming ultrahigh energy electron-neutrino-induced showers. This is due to the relatively large interaction cross sections of these high-energy neutrinos and to the LandauPomeranchuk-Migdal (LPM) effect. The LPM effect is responsible for a significant decrease in the cr...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE Search for Intermediate-Scale Anisotropy by the HiRes Experiment
The HiRes collaboration has searched for intermediate-scale anisotropy of ultrahigh energy cosmic rays in two ways: first a search for variation with declination of the flux of cosmic rays, and second in their arrival directions. The data of the HiRes-II detector was used in the search.
