Energy Resolution of Scintillators in Connection With Track Structure

Optical simulation and experimental measurement of gamma ray energy spectrum of plastic scintillators with different sizes

The application of large plastic scintillators is widely increasing in the different areas of industry, medicine and security due to technical and economic advantages. One of the main disadvantages of these detectors is the unknown position of Compton edge at gamma ray spectrum. In this research, GEANT4/GATE code has been used to simulate the gamma ray spectrum for different volumes of large pl...

the role of thematic structure in comprehending spoken language

in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Non-proportional response and energy resolution of pure SrI2 and SrI2:5%Eu scintillators

Non-proportional response of the scintillation yield of un-doped SrI2 and SrI2:5%Eu was studied using highly monochromatic synchrotron irradiation ranging from 10.5 keV to 100 keV. Measurements were performed at 80 K and 295 K for SrI2, and at 80 K, 295 K, 450 K, and 600 K for SrI2:5%Eu. By making a dense data sampling around the iodine K-edge and using the recently developed K-dip spectroscopy...
