Description
A small arrangement of Geiger-mode avalanche photodiodes (G-APDs) and
two PMTs has been set up on an air Cherenkov telescope for gamma-ray
astronomy in order to test if it is possible to detect Cherenkov light from
cosmic air showers. The aim of this test, a possible proof of concept, is to
evaluate the use of G-APDs as a replacement of PMTs in future imaging air
Cherenkov telescopes. First test results will be presented and advantages
and problems discussed.
