Determination of the emission rate of an Am–Be neutron source with a Bonner sphere spectrometer

Characterization of neutron fields from bare and heavy water moderated 252Cf spontaneous fission source using Bonner Sphere Spectrometer

“…Similar studies were conducted earlier where a number of (α, n) sources were characterized with different instruments. In particular, in 2010 Méndez-Villafañe et al (2010) used Bonner Sphere Spectrometer (BSS) to characterize Am Be 241 -source at the Technical Engineering University of Madrid (UPM). In 2013, a group from National Physical Laboratory (Roberts et al, 2014) measured neutron spectra from B Am 241 -and Am F 241 -using BSS, while a decade earlier, at the same laboratory (Tagziria et al, 2003) characterized Am Li 241 -source using three different spectrometers: BSS, a set of proton recoil proportional counters and a 3 He ionization chamber.…”
