The recoil proton telescope in non-coincidence mode for neutron fluence measurements

The paper describes an alternative approach to use the Los Alamos-type Recoil Proton Telescope for fluence measurements of mono-energetic neutrons with energies above 1 MeV. Traditionally, this type of detectors are used in a 3-coincidence acquisition mode (proportional counter–proportional counter–end detector). This study shows that by only using the end detector and a background reduction method similar results are obtained, with considerably less complexity in the measurement set-up but with larger uncertainties.
