Abstract :
A Large Area Avalanche Photodiode was studied, aiming to access its performance as light detector at low temperatures, down to −80°C. The excess noise factor, F, was measured and found to be approximately independent of the temperature. A linear dependence of F on the APD gain with a slope of 0.00239±0.00008 was observed for gains >100. The detection of low intensity light pulses, producing only a few primary electron–hole pairs in the photodiode, is reported.
