Monte Carlo Calculation of Sensitivity Coefficients.

摘要

A Monte Carlo procedure is presented which allows the evaluation of a complete sensitivity matrix r/sub ilambda/ (= delta r/sub i//deltap/sub lambda/; i numbers the counting rates, lambda the system-parameters) playing a normal (unperturbed) game only. The essential points are: (1) a normal game for the unperturbed system is played according to given transport and collision kernels; (2) the running particle carried a weight - vector with as many components as we have derivatives plus one; (3) during transport and at each collision the weight-vector becomes modified by a weight-matrix; and (4) at each collision point a contribution to the counting rate and its derivatives of each detector is evaluated separately.
