Evaluation of response matrix of a multisphere neutron spectrometer with water moderator
Neutron energy responses of water sphere spectrometers (WSS) to 30 MeV have been
calculated by means of Monte Carlo calculations, using the computer code MCNP4C with ENDF/B-VI.0 neutron cross-section. The calculations ...
Neural network unfolding of neutron spectrum measured by gold foil-based Bonner sphere
Bonner sphere spectrometer (BSS) based on gold foils, as thermal neutron detectors, is one of the
common device for neutron spectrometry. In this paper, the response functions of the Bonner spheres were determined for neutrons with energies...
MEASUREMENT OF THE NEUTRON SPECTRUM BY THE MULTI-SPHERE METHOD USING A BF3 COUNTER
The multi-sphere method, a neutron detection technique, has been improved with a BF3 long
cylindrical counter as a thermal detector located in the center of seven spheres with a diameter
range of 3.5 to 12 inches. Energy response...
Peak shifted properties of the low background NaI(Tl) detectors: An experimental study of response function behavior in different temperature and acquisition time
Due to the necessity of using low background NaI detector in sensitive and accurate measurements, study on the response function variations in different conditions is very important. These types of detectors have different responses in various...
Optimal designs for contingent response models with application to toxicity–efficacy studies
Statistical analysis of autoregressive fractionally integrated moving average models in R
Light transport feature for SCINFUL
An extended version of the scintillator response function prediction code SCINFUL has been developed by incorporating PHOTRACK, a Monte Carlo light transport code. Comparisons of calculated and experimental results for organic scintillators exposed...
Modelling NE213 scintillator response to neutrons using an MCNPX-PHOTRACK hybrid code
This paper reports on how to generate the response function of an NE213 scintillator when exposed to mono-energetic neutrons using the PTRAC card of the MCNPX code. The light transport part of the simulation has been undertaken with the Monte Carlo...
Survey the dynamic trade relations between Iran and South Korea (J-shaped curve
In this paper, using a vector error correction model VECM and impulse response functions, Iran and South Korea\\'s trade balance dynamics during the period 1996 -2008 using quarterly data has reviewed and J-shaped curve for current account tested. The results...
Effects of the Detector-Collimator on the Gamma-Ray Response Function for a NaI(Tl) Detector in a Constant Time of Counts
This study describes the effects of the detector-collimator on the gamma-ray response function for NaI(Tl) detectors with 2 x2 , 3 x3 and 5 x5 dimensions. In present study we have used five different detector-collimators and three gamma ray...
