Özet
Abstract Currently, plastic (organic) scintillators are using in new type positron emission tomography (PET) devices such as J-PET. But, these type scintillators have low gamma energy detection performance. Therefore, an experimental method was proposed to improve gamma ray energy resolution of an organic scintillation detector composed of a BC-420 type crystal. To do this, a timing spectrometer using constant fraction discrimination method was used. Gamma rays from a 137Cs radioactive source were first detected directly then through the timing method, and the obtained results were compared. The results showed that used method is considerably successful in increasing the energy resolution of this type detector. So, it is believe that the J-PET detection performance will be able to enhance if the proposed method can be used in its electronics.
