چکیده

Ground based Cherenkov γ-ray telescopes are sensitive to unpredictable changes in the atmospheric transparency which are difficult to measure and interpret in the absence of a calibrated beam of high energy γ-rays. We use the detector response to Cherenkov emission from cosmic ray initiated air showers to obtain a relative calibration for data obtained under different instrumental and atmospheric conditions as well as over a range of source angles to the Zenith.

The Cosmic Ray Background as a Tool for Relative Calibration of Atmospheric Cherenkov Telescopes

The atmosphere is an intrinsic part of any ground based Cherenkov γ-ray telescope, and the telescope response is therefore sensitive to unpredictable changes in the atmospheric transparency which are difficult to measure and interpret in the absence of a calibrated beam of high energy γ-rays. In this paper, we use the detector response to Cherenkov emission from cosmic ray initiated air showers...

Cosmic-Ray Events as Background in Imaging Atmospheric Cherenkov Telescopes

The dominant background for observations of γ-rays in the energy region above 50 GeV with Imaging Atmospheric Cherenkov telescopes are cosmic-ray events. The images of most of the cosmic ray showers look significantly different from those of γ-rays and are therefore easily discriminated. However, a small fraction of events seems to be indistinguishable from γ-rays. This constitutes an irreducib...

Usa-shepherd-n-abs1-og27-oral Absolute Calibration of Imaging Atmospheric Cherenkov Telescopes

A calibrated laser pulse propagating through the atmosphere produces a flash of Rayleigh scattered light with an intensity that can be calculated very accurately when atmospheric conditions are good. This is used in a technique developed for the absolute calibration of ultra high energy cosmic ray fluorescence telescopes, and it can also be applied to imaging atmospheric Cherenkov telescopes (I...

Minimal Stereoscopic Analysis for Imaging Atmospheric Cherenkov Telescope Arrays

The trajectory of a primary γ-ray detected with an array of at least four atmospheric Cherenkov imaging telescopes can be reconstructed from the shower image centroid positions and geometrical considerations independent of the primary energy. Using only the image centroid positions some cosmic-ray discrimination is also possible. This minimal approach opens the possibility of pushing the analys...

30TH INTERNATIONAL COSMIC RAY CONFERENCE Future imaging atmospheric telescopes: performance of possible array configura- tions for gamma photons in the GeV-TeV range

The future of ground based gamma ray astronomy lies in large arrays of Imaging Atmospheric Cherenkov Telescopes (IACT) with better capabilities: lower energy threshold, higher sensitivity, better resolution and background rejection. Currently, designs for the next generation of IACT arrays are being explored by various groups. We have studied possible configurations with a large number of teles...
