DESCRIPTION:Speakers: Alexander Makeev (National Research Nuclear Universi
 ty MEPhI\, Moscow\, Russia)\nSemiconductor radiation detectors provide hig
 h energy resolution\, with silicon PIN photodiodes being widely utilized d
 ue to their technological simplicity and affordability. This study investi
 gates the feasibility of using the commercially available BPW34 silicon PI
 N photodiode as a low-cost semiconductor detector for X-ray and soft gamma
 -ray spectrometry. A method for determining the optimal reverse bias volta
 ge was developed based on the analysis of $^{241}\\text{Am}$  energy spect
 ra. The optimal operating voltage was established at 60 V\, ensuring the f
 ormation of a depletion region sufficient for complete charge collection w
 hile minimizing noise. Spectra of $^{241}\\text{Am}$\, $^{133}\\text{Ba}$\
 , $^{137}\\text{Cs}$\, and $^{152}\\text{Eu}$ sources were measured at roo
 m temperature using an experimental setup comprising a charge-sensitive pr
 eamplifier and an SBS-79 spectrometric analyzer. A linear calibration was 
 performed based on photopeak positions within the energy range from 5 to 1
 20 keV. The detector's energy resolution (FWHM) was found to be between 1.
 26 and 1.96 keV\, depending on the gamma-ray energy. The results confirm t
 he linearity of the response and the stable operation of the BPW34 PIN pho
 todiode in spectrometric mode\, making it a promising\, cost-effective alt
 ernative to specialized detectors for scientific and educational applicati
 ons.\n\nhttps://indico.particle.mephi.ru/event/626/contributions/6413/
