Abstract
Description
Geigermode avalanche photodiodes (G-APD) are novel photodetectors, which can detect single photons. This type of diodes might become an alternative to photomultipliers (PMT) in next-generation Imaging Air Cherenkov Telescopes. Prospects, limitations and development directions are be discussed. Results from first tests are reported.
