A conceptual design of an advanced 23 m diameter IACT of 50 tons for ground-based gamma-ray astronomy

摘要

A conceptual design of an advanced Imaging Air Cherenkov Telescope with a 23m diameter mirror and of 50 tons weight will be presented. A system photondetection efficiency of 15-17%, averaged over 300-600 nm, is aimed at to lowerthe threshold to 10-20 GeV. Prospects for a second generation camera withGeiger-mode Avalanche Photo Diodes will be discussed.
