Abstract

In the study, we demonstrate the implementation of the "bootstrap" method for a reliable estimation of the statistical error in Neutron Multiplicity Counting (NMC) on plutonium samples. The "bootstrap" method estimates the variance of a measurement through a re-sampling process, in which a large number of pseudo-samples are generated, from which the so-called bootstrap distribution is generated. The outline of the present study is to give a full description of the bootstrapping procedure, and to validate, through experimental results, the reliability of the estimated variance. Results indicate both a very good agreement between the measured variance and the variance obtained through the bootstrap method, and a robustness of the method with respect to the duration of the measurement and the bootstrap parameters.
