X-ray spectrometry with Si photodiodes

Creators

Description

This work envisages the development of a high resolution electromagnetic radiation spectrometry system, based on the use of low cost commercial silicon photodiodes (Siemens SFH00206 and Hamamatsu S2506-02). In order to improve the performance of these photodiodes for high resolution X-ray spectrometry, a cooling system using Peltier cells was developed to decrease the temperature of both photodiode and preamplifier's FET. The best values of the resolution for the 59.5 keV 241 Am γ-ray line, at 9 deg C, were found to be 2.10 keV and 1.82 keV for the Siemens SFH00206 and Hamamatsu S250602 photodiodes respectively.
