Abstract

In this study, the effect of the lead (Pb) shielding on the rate of cosmic rays generally charged particles coming through the atmosphere were studied. The measurements were all done indoors by using a prototype detector consisting of a 20 × 20 × 1.4 cm 3 KURARAY organic scintillator read by 3 mm 2 SensL silicon photomultiplier. The measurements were carried out by using lead plates of different thickness in order to shield the charged particles and investigate Rossi transition curve by using this system. The detector was placed under the lead block and then recorded the coincidence only when both detectors were triggered simultaneously. The Cosmic ray fluxes over the building (sea level firstly simulated by using the CRY software and then the attenuation effect of the construction elements on the measured cosmic ray rate was carried out by using GEANT4 simulation program and this effect was taken into account in the given results.

Özet

Bu çalışmada kurşun (Pb) blok çoğunlukla yüklü parçacıklardan oluşup atmosferden gelen kozmik ışın oranı üzerindeki etkisi çalışmıştır. Ölçümler 3mm 2 SensL silikon fotoçoğaltıcı tarafından okunan 20 × 20 × 1.4 cm 3 KURARAY organik sintilatörden oluşan bir prototip detektörü kullanılarak bina içinde yapılmıştır. Farklı kalınlıklardaki kurşun tabakalar yüklü parçacıklara karşı kalkan görevi görmesi ve Rossi geçiş eğrisini elde etmek amacıyla ölçümlerde kullanılmıştır. Kurşun blok detektörler arasına yerleştirilerek her iki detektörden gelen eş zamanlı tetiklenmeler kaydedilmiştir. İlk olarak kozmik ışın üretim, CRY yazılımı kullanılarak binadaki (deniz seviyesi) kozmik ışın akısı benzetim edilmiş ve daha sonra yapı malzemelerinin ölçülen kozmik ışın oranı üzerindeki zayıflatma etkisi dikkate alınarak GEANT4 programında benzetimi yapılmış ve bu etki verilen sonuçlarda dikkate alınmıştır.
