Gamma Ray Astronomy from 1011 to 1014 EV Using the Atmospheric Cerenkov Technique

Book Description
The atmospheric Cerenkov technique has been widely used over the past two decades to search for point sources of 1011 to 1014 eV gamma rays. In this technique the gamma rays are detected by the Cerenkov light emission from the small air showers that they create in the atmosphere. The basic principles underlying the technique are reviewed with particular reference to the experiments performed to date, (September 1977). The production and absorption processes that pertain to this energy region are discussed. There is strong evidence for the detection of 10^12 eV gamma rays from NP0532, Centaurus A and Cygnus X-3. Models for these, and other sources for which upper limits have been derived, are outlined. There appears to be no other technique that can compete with the atmospheric Cerenkov technique in this energy range. The methods by which the present flux sensitivity can be reduced by factors of 10 - 100 are discussed; it is also possible to extend observations into the previously unexplored 10 - 100 Gev energy range.

Category : Cosmic rays
Languages : en
Pages : 158
Book Description
A gamma-ray detector consisting of scintillation counters and a spark chamber to convert gamma rays to electron-positron pairs was flown with a balloon to an altitude of 125,000 feet for 7 hours on 28 May 1966. The photon spectrum at 4 g cm-2 atmospheric depth is reported. The angular resolution of the detector and method of determining statistical upper limits of fluxes are thoroughly discussed.
