| Sumario: | Avalanche Photodiodes (APDs) will be used as photodetectors for the CMS crystal barrel calorimeter, made of lead tungstate (PWO) scintillating crystals. After two years of strong R&D effort a significant progress was achieved, in collaboration with manufacturers, in the relevant properties of the device for LHC applications. Quantum efficiency, noise contributions and radiation resistance measurements of APDs are presented. |
