چکیده

Atmospheric Čerenkov telescopes are used to detect electromagnetic showers from primary gamma rays of energy > 300 GeV and to discriminate these from cascades due to hadrons using the shape and orientation of the Čerenkov images. The geomagnetic field affects the development of showers and diffuses and distorts the images. When the component of the field normal to the shower axis is sufficiently large (> 0.4 G) the performance of gamma ray telescopes may be affected.

Geomagnetic effects on atmospheric Čerenkov images

Atmospheric Čerenkov telescopes are used to detect electromagnetic showers from primary gamma rays of energy ∼ 300 GeV – ∼ 10 TeV and to discriminate these from cascades due to hadrons using the Čerenkov images. The geomagnetic field affects the development of showers and is shown to diffuse and distort the images. When the component of the field normal to the shower axis is sufficiently large ...

Monte Carlo studies on the sensitivity of the HEGRA imaging atmospheric Čerenkov telescope system in observations of extended γ-ray sources

In this paper, we present the results of Monte Carlo simulations of atmospheric showers induced by diffuse γ-rays as detected by the high-energy gamma-ray astronomy (HEGRA) system of five imaging atmospheric Čerenkov telescopes (IACTs). We have investigated the sensitivity of observations on extended γ-ray emission over the entire field of view of the instrument. We discuss a technique to searc...

Pachmarhi Array of Čerenkov Telescopes

Very High Energy (VHE) γ−ray Astronomy observations are planned to be carried out at Pachmarhi in the central Indian state of Madhya Pradesh using the well known atmospheric Čerenkov technique. An array of 25 Čerenkov telescopes is currently under construction. Using this array it is proposed to sample the Čerenkov light pool at various distances from the shower core in order to estimate the la...

Atmospheric Čerenkov Telescopes: A Next-Generation Detector for Ground-Based High Energy Gamma-ray Astronomy

The construction of the H.E.S.S. (High Energy Stereoscopic System), a superior system of four 12 m imaging atmospheric Čerenkov telescopes, has been completed recently in the Namib desert close to Windhoek, at 1800 m above sea level. This new generation of ground-based gamma-ray detectors has an energy threshold of about 100 GeV in observations at zenith and a sensitivity of about 1% Crab flux ...
