Development of an atmospheric Cherenkov imaging camera for the CANGAROO-III experiment
نویسندگان
چکیده
A Cherenkov imaging camera for the CANGAROO-III experiment has been developed for observations of gamma-ray induced air-showers at energies from 1011 to 10 eV. The camera consists of 427 pixels, arranged in a hexagonal shape at 0.17◦ intervals, each of which is a 3/4-inch diameter photomultiplier module with a Winston-cone–shaped light guide. The camera was designed to have a large dynamic range of signal linearity, a wider field of view, and an improvement in photon collection efficiency compared with the CANGAROO-II camera. The camera, and a number of the calibration experiments made to test its performance, are described in detail in this paper.

Status of an Atmospheric Cherenkov Imaging Camera for the CANGAROO–III Experiment and Perspective of the Field
CANGAROO–III is an experiment aiming at studying the properties of very high energy gamma rays from celestial objects in the southern sky. We use an array of 4 imaging atmospheric Cherenkov telescopes in Australia. The observation with the first telescope (CANGAROO–II) started in 1999 and the data have been analyzed. The second telescope was constructed in 2002 and stereoscopic observations sta...
