Status of the CANGAROO-III project

Abstract

The CANGAROO-III telescope array for sub-TeV gamma-ray astronomy consists of four 10 m atmospheric Cherenkov telescopes. The construction of the fourth telescope was completed in summer, 2003 and a stereoscopic observation with a local trigger system was started in March 2004. In December 2004, a global stereo trigger system was installed and real-time stereoscopic operation was started. The telescope performance is checked using star images taken by a CCD camera, and analyses of stereo data and tuning of Monte Carlo simulations has been carried by use of local muons and observations data of the Crab Nebula.
