Developing a Virtual Counter for Radiation Detection Systems

Abstract

A virtual counter was developed to count the signals from a scintillation detector. After the signals were processed by some electronic devices, they were counted by the virtual counter and a real counter. The counts obtained from both counters were accumulated via different amplifier gains and source-to-detector distances to investigate their effects on the recorded counts. The results from the virtual counter were compared with those of the real one. It was concluded that the developed virtual counter could be used to count the radiation detector signals like a real counter.

Radyasyon Dedeksiyon Sistemleri için Bir Sanal Sayıcı Geliştirilmesi

Abstract

Bu çalışmada, sintilasyon dedektöründen gelen sinyalleri saymak için bir sanal sayıcı geliştirilmiştir. Sinyaller bazı elektronik cihazlar tarafından işlendikten sonra sanal ve gerçek sayıcılar tarafından sayılmıştır. Farklı yükseltici kazançları ve kaynak dedektör mesafeleri için her iki sayıcıdan sayımlar alınmıştır. Sanal sayıcıdan alınan sonuçlar gerçek sayıcıdan alınan sonuçlarla karşılaştırılmıştır. Geliştirilen sanal sayıcının gerçek bir sayıcı gibi radyasyon dedektör sinyallerini saymak için kullanılabileceği sonucuna varılmıştır.
