Reproducibility of Subcritical Measurements: Five Years of Plutonium Sphere Data

摘要

This report compiles neutron data on Beryllium Reflected Plutonium (BeRP) ball measurements that have taken place at the Device Assembly Facility (DAF) from July 2007 through May 2012. The measurement setups, detectors used and results are discussed. The main purpose of this report is to compare measured results on configurations that were measured using the same (or similar) setups during different measurement campaigns. This information can be used to estimate reproducibility of subcritical experiments.
