WebThe ANTECH Model N2442 Active Well Coincidence Counter (AWCC) is a transportable high efficiency neutron counter for the measurement of plutonium and uranium. The AWCC was originally developed by the Los Alamos National Laboratory (LANL) in the United States. ANTECH has added performance enhancing features including: Webcharacteristics for the FB-Line Neutron Multiplicity Counter (FBLNMC). The FBLNMC 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 (57%) detector that has 113 3He tubes in a high-density polyethylene body.
