Low-temperature performance of a large area avalanche photodiode
نویسندگان
چکیده
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 0.0023970.00008 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. r 2003 Elsevier Science B.V. All rights reserved.

Performance characteristics of the response of a Peltier-cooled large-area avalanche photodiode are investigated. Detector gain, energy linearity, energy resolution and minimum detectable energy are studied at different operation temperatures. Detector energy resolution and lowest detectable X-ray energy present a strong improvement as the operation temperature is reduced from 25 to 15 C and sl...
متن کاملExcess noise factor in large area avalanche photodiodes for different temperatures
The excess noise factor (ENF) of a large area avalanche photodiode was measured as a function of gain for different temperatures, in the 40 to 27 C range. Results show that ENF does not depend significantly with temperature attaining values of about 1.8 and 2.3 for gains of 50 and 300, respectively. r 2004 Elsevier B.V. All rights reserved.

Two large-area, low noise, high speed fluorescence detectors have been built. One detector consists of a photodiode with an area of 28 mm x 28 mm and a low noise transimpedance amplifier. This detector has a input light-equivalent spectral noise density of less than 3 pW/ √ Hz, can recover from a large scattered light pulse within 10 μs, and has a bandwidth of at least 900 kHz. The second detec...
