Abstract
A pulse shape discrimination setup was developed and the pulse shape discrimination method was applied to γ-rays emitted from 137Cs radioisotope to test its discrimination performance. The setup was used to discriminate the photopeak radiations from the non-photopeak ones arising from scattering, backscattering, background, low-energy X-rays and electronic noise etc. To perform this, pulse shape discrimination method which is a kind of timing process was used. The discrimination was performed in the region very close to the photopeak of the radioisotope. The developed setup showed its success in the discrimination of non-photopeak signals from the original photopeak ones.

Abstract
Bu çalışmada, bir puls şekli ayırma devresi geliştirilmiştir ve bu devreyi test etmek için 137Cs radyoizotopunun yayımladığı gamma ışınları üzerine puls şekli ayırma yöntemi uygulanmıştır. Bu devre, elektronik gürültü, düşük enerjili X-ışınları, tabi fon, geri saçılma ve saçılmalar nedeniyle ortaya çıkan diğer etkileri fotopik radyasyonlarından ayırmak için kullanılmıştır. Bunu gerçekleştirmek için bir çeşit zamanlama işlemi olan puls şekli ayırımı metodu kullanılmıştır. Ayırma işlemi radyoizotopun fotopikine yakın enerjideki bölgede gerçekleştirilmiştir. Geliştirilen devre, orijinal fotopik sinyallerinden fotopike ait olmayan sinyallerin ayırt edilmesinde başarılı olduğunu göstermiştir.

Selcuk University Journal of Science Faculty accepts articles in Turkish and English with original results in basic sciences and other applied sciences. The journal may also include compilations containing current innovations.
It was first published in 1981 as "S.Ü. Fen-Edebiyat Fakültesi Dergisi" and was published under this name until 1984 (Number 1-4).
In 1984, its name was changed to "S.Ü. Fen-Edeb. Fak. Fen Dergisi" and it was published under this name as of the 5th issue.
When the Faculty of Letters and Sciences was separated into the Faculty of Science and the Faculty of Letters with the decision of the Council of Ministers numbered 2008/4344 published in the Official Gazette dated 3 December 2008 and numbered 27073, it has been published as "Selcuk University Journal of Science Faculty" since 2009.
It has been scanned in DergiPark since 2016.
