This paper describes a novel 24-keV monoenergetic neutron source that consists of an iron filter and a thick lithium target. The 24 keV neutrons are obtained with iron filtering of a neutron beam from the {sup 7}Li(p,n){sup 7}Be reaction near threshold energy using the 4 MV Pelletron accelerator. Neutron spectra were calculated using the NRESP-ANT simulation code. This neutron source was investigated using a {sup 3}He cylindrical proportional counter to measure the spatial distribution and neutron flux.
