Comparison Of Neutron Coincidence And Multiplicity Counting Techniques For Safeguards
Neutron counters have been used by safeguard inspectors worldwide for over 20 years to accurately perform Non-Destructive Assays of pure samples of plutonium and uranium. These systems rely on the neutron coincidence counting technique to separate time-correlated fission neutrons from random, uncorrelated neutrons to determine the fissile mass. Impure samples such as mixed-oxide (MOX) scrap mat...
متن کاملNeutron Detection and Counting Introduction
Plutonium and uranium isotopes decay by alpha particle emission. The alpha particle is absorbed by the nuclei of the low atomic number elements (Li, B, Be, O, F, C, Si, etc.) and a neutron is produced. The yield depends upon the chemical composition of the matrix and the alpha production rate for plutonium and uranium. Neutrons from (α,n) reactions are produced randomly (not time-correlated) an...

متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
AZ Comparison of Deadtime Correction Factors for Passive Neutron Multiplicity Counting of Correlated and Non - Correlated Neutron Sources - 9298
Traditional deadtime correction methods for Passive Neutron Multiplicity Counting (PNMC) have been found to be potentially accuracy limiting at high average (or sustained) count rates and in the case where highly correlated rates occur over a short coincidence gate width (high instantaneous rates associated with high multiplicity bursts). It is costly to retrofit new hardware to existing assay ...
