Alfa Parçacık Dedektörleri için YAG:Ce Kompozit Sintilatörlerde Kalınlık ve Bileşimin Etkisi

Öz

Bu çalışma, karışık radyasyon alanlarında YAG:Ce kompozit sintilatörler kullanan görüntüleme tabanlı alfa parçacık dedektörlerinin performansını değerlendirmektedir. Farklı kalınlıklara (0,1 mm, 0,5 mm ve 1,0 mm) ve YAG:Ce ile epoksi oranlarına (5%, 15% ve 20%) sahip sintilatörler, algılama verimliliği, ışık çıktısı ve enerji çözünürlüğünü analiz etmek amacıyla GEANT4 simülasyon paketi kullanılarak modellenmiştir. Sonuçlar, 0,5 mm kalınlığında ve %90 YAG:Ce ile %10 epoksi içeren sintilatörün, simüle edilen sintilatörler arasında bir alfa parçacık dedektörü için en uygun yapılandırma olduğunu göstermektedir. Ayrıca, fantom tabanlı simülasyonlar, dedektörün alfa parçacıklarını net bir şekilde görüntüleyebildiğini ortaya koymuştur.

Impact of Thickness and Composition on YAG:Ce Composite Scintillators for Alpha Particle Detectors

Öz

This study evaluates the performance of imaging-based alpha particle detectors using YAG:Ce composite scintillators in mixed radiation fields. Scintillators with varying thicknesses (0.1 mm, 0.5 mm, and 1.0 mm) and YAG:Ce to epoxy ratios (5%, 15%, and 20%) were modeled using the GEANT4 simulation package to analyze the detection efficiency, light output, and energy resolution of the alpha particle detectors. The results indicate that a 0.5 mm thick scintillator with 90% YAG:Ce and 10% epoxy is the optimal configuration among the simulated scintillators for an alpha particle detector. Additionally, phantom-based simulations demonstrated that the detector is capable of producing clear imaging of alpha particles.
