Description

Geiger-mode Avalanche Photo Diodes (G-APD) bear the potential to significantly improve the sensitivity of Imaging Air Cherenkov Telescopes (IACT). Therefore we are currently building the First G-APD Cherenkov Telescope (FACT) by refurbishing an old IACT with a mirror area of 9 square meters and construct a new, fine pixelized camera using novel G-APDs. The main goal is to evaluate the performance of a complete system. This is an important field test to check the feasibility of G-APD based cameras to replace at some time the PMT-based cameras of planned future IACTs like AGIS and CTA. In this talk, we present the basic design of such a camera as well as some important details to be taken into account. Additionally, we will make a critical comparison of PMTs and G-APDs concerning their use in IACTS.
Please indicate "poster" or "plenary" session. Final decision will be made by session coordinators. plenary
