X-ray spectrometry with Peltier-cooled large area avalanche photodiodes
نویسندگان
چکیده
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 slower improvements are achieved for temperatures below 10 C. 2003 Elsevier B.V.

Application of large-area avalanche photodiodes to energy-dispersive x-ray fluorescence analysis
The performance of several large-area avalanche photodiodes (LAAPDs) for application to x-ray spectrometry at room temperature was investigated. Optimum detector performance was obtained for gains of about 50–70. Good energy linearity of the LAAPDs’ response to x-rays was observed up to energies of about 25 keV. For this energy range the space charge effects are negligible for gains below 100–1...
متن کاملApplication of large-area avalanche photodiodes to X-ray spectrometry of muonic atoms
Large-area avalanche photodiodes have been investigated as 1.9-keV X-ray detectors for the muonic hydrogen Lamb-shift experiment. We report experimental tests carried out for evaluation of the avalanche photodiode capabilities for X-ray detection in the intense radiation and low counting rate environment of experiments with muonic atoms. Several muonic atoms were used and it was shown that the ...
متن کاملResponse of large area avalanche photodiodes to low energy x rays.
For an experiment to study neutron radiative beta-decay, we operated large area avalanche photodiodes (APDs) near liquid nitrogen temperature to detect x rays with energies between 0.2 keV and 20 keV. Whereas there are numerous reports of x ray spectrometry using APDs at energies above 1 keV, operation near liquid nitrogen temperature allowed us to reach a nominal threshold of 0.1 keV. However,...
متن کاملRecent progress of avalanche photodiodes in high-resolution X-rays and γ-rays detection
We have studied the performance of large area avalanche photodiodes (APDs) recently developed by Hamamatsu Photonics K.K, in high-resolution X-rays and γrays detections. We show that reach-through APD can be an excellent soft X-ray detector operating at room temperature or moderately cooled environment. We obtain the best energy resolution ever achieved with APDs, 6.4 % for 5.9 keV X-rays, and ...
متن کاملNon-linear behaviour of large-area avalanche photodiodes
The characterisation of photodiodes used as photosensors requires a determination of the number of electron–hole pairs produced by scintillation light. One method involves comparing signals produced by X-ray absorptions occurring directly in the avalanche photodiode with the light signals. When the light is derived from light-emitting diodes in the 400–600 nm range, significant non-linear behav...
