摘要：

This paper describes a procedure for estimating assay variance for the neutron multiplicity counters that are being developed to assay special nuclear materials. The procedure estimates the moments of the expected neutron multiplicity distribution and calculates the expected variance without requiring a sample measurement. Results of the procedure are compared with actual measurements made with existing prototype counters. Assay variance is used as a figure of merit to compare the counters and to identify the most important design parameters. In the future, this procedure can be used to optimize the design of new counters. © 1990.
