2017, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :As stated, in the present study, we will restrict our discussions to the third factor only: statistical uncertainty. Quantification of the statistical uncertainty of the measurement variance in NMC, naturally, has been studied before, and there are several publications regarding both the estimation ([10–12], to state a few) and the optimization [13,14] of the measurement variance. The outline of the present study is to perform a comparative research between three of the both basic and widely used methods for estimating the statistical uncertainty in the measurements.
Variance estimation in neutron coincidence counting using the bootstrap method
2015, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :Estimating the random variance of in NMC measurements is of utmost importance in estimating the reliability of a detection system. Naturally, the measurement variance has been studied before, and there are several publications regarding both the estimation [1,6,7] and the optimization [8,9] of the measurement variance. The emphasis in previous works is mainly on analytic expressions for the random variance, and the bootstrap method (or any other re-sampling method) was somewhat neglected.
Statistical estimation of the performance of a fast-neutron multiplicity system for nuclear material accountancy
2015, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :To assess the expected performance of the FNMS in the context of nuclear material assay measurements, an analytical comparison was made between the prototype FNMS and a commercial HLNCC (JCC-31, Canberra Industries, Meriden, Connecticut), again using RSD as the figure of merit. For this analysis the HLNCC system parameters were taken from Ref. [37]. A summary of the parameters used in the calculations for both detection systems is shown in Table 4.
