The image camera of the 17 in circle divide MAGIC telescope, an air Cherenk
ov telescope currently under construction to be installed at the Canary isl
and La Palma, is described. The main goal of the experiment is to cover the
unexplored energy window from similar to 10 to similar to 300 GeV in gamma
-ray astrophysics. In its first phase with a classical PMT camera the MAGI
C telescope is expected to reach an energy threshold of similar to 30 GeV.
The operational conditions, the special characteristics of the developed PM
Ts and their use with light concentrators, the fast signal transfer scheme
using analog optical links, the trigger and DAQ organization as well as ima
ge reconstruction strategy are described.
The different paths being explored towards future camera improvements, in p
articular the constraints in using silicon avalanche photodiodes and GaAsP
hybrid photodetectors in air Cherenkov telescopes are discussed. (C) 2001 E
