A measurement of the flux, angular distribution and energy spectra of cosmic ray induced neutrons at fission energies

Abstract

When searching for SNM simply designing a better detector to optimize the signal S from the source is not enough. It is important to know the background B to maximize S/N, where N is the noise in B. Cosmic rays are a dominant source of neutron background. It is therefore important to know their flux, angular and energy distribution. Over the last 50 years… (More)
