Plutonium scrap multiplicity counter operation manual
Technical Report
·
OSTI ID:10115560
This manual describes the design features and performance and operating characteristics for the plutonium scrap multiplicity counter (PSMC). It counts neutron multiplicities to quantitatively assay plutonium in many forms, including impure scrap and waste. Monte Carlo neutronic calculations were used to design the high-efficiency (55%) detector using eighty {sup 3}He tubes in a high-density polyethylene body. The new multiplicity shift-register electronics can sort multiplicities up to 256. The PSMC can be applied to plutonium masses in the range from a few milligrams to 5 kg; both conventional coincidence counting and multiplicity counting are used as appropriate. This manual gives the performance data and preliminary calibration parameters for the PSMC.
