Spectral unmixing applied to fast identification of γ-emitting radionuclides using NaI(Tl) detectors
The neutron capture cross sections of 107 Pd were measured using the Accurate Neutron-Nucleus Reaction Measurement Instrument (ANNRI) at Japan Proton Accelerator Research Complex (J-PARC). Capture γ-rays detected with a NaI(Tl) spectrometer. incident energy was determined by time-of-flight method. preliminary section derived from thermal to resonance region. In region, parameters analysis REFIT ...
In this paper, an algorithm base on Monte Carlo simulation for pileup effect in gamma spectrum of a detection system is presented whose its code was written in FORTRAN language. The code can be run in paralayzable and nonparalazable mode to obtain the pileup distortion and value of pulses pileup for any detection system. The result show, that the computed spectrum of 137Cs is in good agreement...
The SND is a non-magnetic detector deployed at the VEPP-2000 e + − collider (BINP, Novosibirsk) for hadronic cross-section measurements in center of mass energy range below 2 GeV. important part hodoscopic electromagnetic calorimeter (EMC) with three layers NaI(Tl) counters. EMC signal shaping and digitizing electronics based on FADC allow us to obtain both deposition arrival time. We demonstra...
The DAMA/LIBRA observation of an annual modulation in the detection rate compatible with that expected for dark matter particles from galactic halo has accumulated evidence more than twenty years. It is only hint a direct elusive matter, but it strong tension negative results other very sensitive experiments, requiring ad-hoc scenarios to reconcile all present experimental results. Testing resu...
The 63Cu(α,γ)67Ga reaction cross-section was measured in the energy range between 5 and 9 MeV, which is relevant to p-process nucleosynthesis. experiment conducted at Dynamitron Tandem Laboratory, of Ruhr-University Bochum Germany, by applying 4π γ-summing method, using a 12"×12" NaI(Tl) single crystal scintillator. preliminary results are compared with previous measurements theoretical TALYS c...
Interaction of fast neutrons with oxygen atoms of cooling water in reactor core leads to the production of 16N isotope which emits 6.13 MeV gamma ray. A system is developed to measure the 16N gamma ray activity using a5.08cm ×5.08cm NaI(Tl) detector. A suitable electronic system is used to count 16N gamma rays in different reactor powers in order to calibrate the 16N system in terms of reacto...
