Abstract

In this study, the zenith angle distribution of the ground level cosmic ray flux have been measured at 900 meters above the sea level by using the developed prototype detector. The mea- surements have been done in Experimental Particle Physics Laboratory, Department of Physics, AIBU Bolu. The method used to carry out the experiment is by using simultaneous particle hits on two scintillator boxes that are arranged in tower mode then counts will accumulate in the scin- tillator counter boxes. This detector prototype provides a simpler, cheaper and suitable alternative to the common cosmic ray detectors for the detection of particles at ground level. The orientation of module is in the south-east direction. The fluxes and rates were measured for different zenith angles between 0and 90o. The attenuation effect of the architectural components on the mea- sured cosmic ray flux was carried out by using GEANT4 simulation program and this effect was taken into account in the given results.

Deniz Seviyesinin 900 m Üstünde Kozmik Işın Akısının Açısal Bağımlılık Çalışması

Abstract

Bu çalışmada, zemin seviyesindeki kozmik ışın akısının zenit açısı dağılımı, geliştirilen prototip detektörü kullanılarak deniz seviyesinden 900 metre yukarıda ölçülmüştür. Ölçümler, Bolu Abant İzzet Baysal Üniversitesi Fizik Bölümü Deneysel Parçacık Fiziği Laboratuvarında yapılmıştır. Ölçümleri gerçekleştirmek için kullanılan yöntem, kule modunda düzenlenmiş iki sintilatör kutusu üzerindeki eşzamanlı parçacık darbelerini kullanmaktır, daha sonra sayımlar sintilatör sayaç kutularında birikecektir. Bu detektör prototipi, parçacıkların yer seviyesinde tespit edilebilmesinde bilinen kozmik ışın detektörlerine göre daha basit, daha ucuz ve uygun bir alternatif sunar. Akılar ve oranlar, 0o ve 90o arasındaki farklı zenit açıları için ölçülmüştür. Mimari bileşenlerin ölçülen kozmik ışın akısı üzerindeki zayıflama etkisi, GEANT4 simülasyon programı kullanılarak gerçekleştirilmiş ve bu etki verilen sonuçlarda dikkate alınmıştır.
