Keywords: | Photodetectors; Excess noise factor; Avalanche photodiode | Issue Date: | 2003 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 504:1-3 (2003) 53-57 | 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. | URI: | https://hdl.handle.net/10316/4476 | Rights: | openAccess |
