Abstract

Bu çalışmada kurşun (Pb)
blok çoğunlukla yüklü parçacıklardan oluşup atmosferden gelen kozmik ışın oranı
üzerindeki etkisi çalışmıştır. Ölçümler 3mm2 SensL silikon
fotoçoğaltıcı tarafından okunan 20
× 20 × 1.4
cm3 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.

Study of Shielding Effects on Cosmic Ray Rate

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 cm3 KURARAY organic scintillator read by 3 mm2
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.
