Description

The LEMC Large Epi-Thermal Multiplicity Counter is a high performance neutron coincidence counter designed for measuring the multiplicity of the neutron emission from both spontaneous fission and induced-fission reaction in plutonium and uranium. The LEMC system was developed to measure impure plutonium and mixedoxide (MOX) scrap materials for safeguards and inventory control applications. Intended for the measurement of items up to 40 liters (10 gallons) in volume, the counter is designed to provide improved measurement precision through the use of multiple cadmium layers and high pressure (10 atm) 3He proportional tubes.
