With the goal of measuring precise gamma-ray intensities for short-lived (< 5 s) accelerator-produced activities, we have calibrated the efficiency of an HPGe detector between 53 and 1836keV to sub-percent precision with a combination of source measurements and Monte Carlo calculations. Using known or independently measured detector dimensions, we have achieved both relative and absolute agreem...
Triglycine sulfate, TGS, and its phosphated counterpart, TGSP, have been grown by saturation solution method and were investigated for growth conditions and crystallographic parameters.Structural analysis equipments such as X-ray diffraction and back-scattering laser micro-Raman spectroscopy have been employed for the investigation of the grown crystals and the experimental results obtained for...
The first true coaxial 18–fold segmented n–type HPGe prototype detector produced by Canberra–France for the GERDA neutrinoless double beta-decay project was tested both at Canberra–France and at the Max–Planck–Institut für Physik in Munich. The main characteristics of the detector are given and measurements concerning detector properties are described. A novel method to establish contacts betwe...
A measurement station dedicated for quantitative radiological characterisation of naturally occurring radionuclides in a metallurgical company and based on gamma-ray spectrometry was developed. The station is intended for performing quality control of final non-ferrous metal products and for radiological checks of incoming materials. A low-background point-contact HPGe-detector was used and the...
حساسیت آشکارساز فلز از نوع میدان الکترومغناطیسی مستقیما به پایداری آن بستگی دارد و هر اندازه که حساسیت مورد نظر بیشتر باشد بهمان اندازه تکرار تنظیم پیچ های کنترل برای تعادل دستگاه افزایش می یابد.بنابراین برای دسترسی به حساسیت ماکزیمم ، استفاده از شبکه جبران خود کار((برای از بین بردن هرگونه جابجائی تغییرات دما)) ضروری است .زیرا گرچه این نوع سیگنال بوجود آمده در ورودی آشکار ساز کوچک است ولی پس از...
