Modeling of the new neutron filter with 5.6 keV energy

New filtered neutron beam with the average energy of 5.6 keV was simulated using the latest versions of the evaluated nuclear data libraries ENDF/B-VII.1 and CENDL-3.1. The main components of this new filter are: 60Ni, manganese, sulfur, and cerium oxide. Expected filter characteristics are: the ave...

Summary:New filtered neutron beam with the average energy of 5.6 keV was simulated using the latest versions of the evaluated nuclear data libraries ENDF/B-VII.1 and CENDL-3.1. The main components of this new filter are: 60Ni, manganese, sulfur, and cerium oxide. Expected filter characteristics are: the average energy is 5.62 keV; neutron line width at half maximum is 1.73 keV; the purity of the main line is 84 %; the neutron flux is 2⋅105 n/(s⋅cm2). Experimental testing of the parameters of this new filter will be done during the next campaign of the reactor WWR-M.
