How to focus a Cherenkov telescope
Cherenkov telescopes image the Cherenkov emission from air showers. A priori, it is not obvious if the ‘best’ images are achieved by measuring Cherenkov photon angles, i.e. focusing the telescope at infinity, or by considering the air shower as an object to be imaged, in which case one might focus the telescope on the central region of the shower. The issue is addressed using shower simulations...
متن کاملIntercalibration of Cherenkov Telescopes in Telescope Arrays
A simple analysis technique is described which allows to intercalibrate the response of imaging atmospheric Cherenkov telescopes in stereoscopic telescope arrays at a level of 1-2%. With the next-generation imaging atmospheric Cherenkov telescopes currently under construction, stereoscopic arrays of telescopes such as VERITAS [1], CANGAROO III [2] and H.E.S.S. [3] play a dominant role. Stereosc...
متن کاملTowards an optimized design for the Cherenkov Telescope Array
The Cherenkov Telescope Array (CTA) is a future instrument for very-high-energy (VHE) gamma-ray astronomy that is expected to deliver an order of magnitude improvement in sensitivity over existing instruments. In order to meet the physics goals of CTA in a cost-effective way, Monte Carlo simulations of the telescope array are used in its design. Specifically, we simulate large arrays comprising...
متن کاملThe MAGIC Cherenkov Telescope for gamma ray astronomy
The Major Atmospheric Gamma ray Imaging Cherenkov Telescope (MAGIC) is in commissioning phase and will start to become fully operative by the end of 2003. Located at El Roque de los Muchachos in La Palma (Canary Islands, Spain), it has the largest reflector area (17 m diameter) of all the existing Cherenkov telescopes. New technologies have been used to reduce the energy threshold for gamma-ray...
متن کاملPrecision Measurement of Optical Pulsation using a Cherenkov Telescope
During 2003, a camera designed to measure the optical pulsations of pulsars was installed on a telescope of the H.E.S.S. array. The array is designed for γ-ray astronomy in the ∼ 100 GeV 100 TeV energy regime. The aims of this exercise were two-fold: to prove the pulsar timing capabilities of H.E.S.S. on all relevant time-scales, and to explore the possibility of performing sensitive optical pu...
