Abstract
ROOT is a framework for a physicist to save data, to access the data, to mine the data and to publish results in a graphical interface. As a gamma ray spectroscopist, one of the most useful features of it is to estimate and to calculate the integral of a peak area. When this is done, not always these peaks can be isolated easily. Also, the methods differ the results of the total counts under the peak areas. Regardless of the detector types, the written C++ codes for ROOT can be easily implemented and adjusted for any peak situation. As an example, Maestro, which is a multichannel analyzer (MCA) emulation software package, is one of the most common software for NaI detector type. However, the users of this package mostly do not know the details of its procedure to collect and integrate the total counts for each individual gamma-ray. For that reason, it will be useful to indicate the comparisons for an experimental data by using Covell and Total Peak Area (TPA) methods between ROOT and Maestro.

Covell ve Toplam Pik Alanı Methodlarıyla Gama Işınlarının Analizleri Yapılırken ROOT Uygulamasının Kullanımı
Abstract
ROOT, bir fizikçi için veri depolamak, veriye ulaşmak, veriyi araştırmak ve sonuçları grafiksel bir arayüzle ortaya koymaya yarayan bir çalışma alanıdır. Gama ışını spektroskopisi uzmanı olarak, ROOT uygulamasının en yararlı özelliklerinden biri, bir gama ışını pik alanını tahmin edebilmesi ve hesaplayabilmesidir. Bu işlem yapılırken, her zaman pikler kolaylıkla izole edilemezler. Ayrıca, seçilen yönteme göre toplam pik alanı sonuçları da farklılık gösterecektir. Dedektör tipine bağlı olmaksızın, ROOT için yazılmış C++ kodları herhangi bir pik durumu için kolaylıkla uygulanabilmekte ve ayarlanabilmektedir. Örneğin, çok kanallı analizör örneği olan Maestro yazılım paketi, NaI dedektörleri için en çok kullanılan yazılımlardan biridir. Buna rağmen, bu yazılımın kullanıcıları her bir gama ışını sayım sayısının nasıl toplandığını ve hesaplandığını detaylı bir şekilde bilmemektedir. Bu yüzden, deneysel bir veri üzerinden Covell ve Toplam Pik Alanı metodlarının karşılaştırmasını ROOT ve Maestro arasında yapmak faydalı olacaktır.
