The light-yield response of a NE-213 liquid-scintillator detector

[K W Geiger; C K Hargrove; NATIONAL RESEARCH COUNCIL OF CANADA OTTAWA (Ont.) DIV OF APPLIED PHYSICS.;] -- The neutron energy spectrum of an alloyed source was determined with a proton recoil spectrometer. The spectrum shows fairly broad maxima at 3.5 and 5 MeV and extends up to 11.5 MeV. The performance of wax neutron howitzers has been studied using a 200 mCi Am-Be neutron source. A smaller mouth diameter produces a greater thermal to epithermal ratio, and a higher thermal flux close to the source; however, small mouth diameters also produce large Section III (neutron measurements) of the Comité Consultatif des Rayonnements Ionisants, CCRI, conducted a key comparison of primary measurements of the neutron emission rate of an 241Am-Be(α,n) radionuclide source. A single 241Am-Be(α,n) source was circulated to … 2012-03-20 2004-12-01 The Am–Be neutron source was measured over the effective centre varies with energy; so it has to be neutron spectral distribution obtained using measured for the energy spectrum in which it is FLUKA and it is found to be 3.08 counts/(n cm ). used.

2011-04-16 Am/Be neutron source was modelled as an isotropic point source placed inside the moderator. Also, the detector was modelled as a helium gas filled spherical material, with diameter 20.8 cm. The neutron source and the detector were place 90 cm apart inside a rectangular world as shown in Figure 1 In the absence of a formal program to handle {sup 238}Pu/Be and {sup 241}Am/Be neutron sources, Los Alamos has responded to several emergency requests to receive andmore » This presentation will: (1) review the established {sup 239}Pu neutron source recovery program at Los Alamos, (2) detail plans for a more extensive neutron source disposal program, and (3) focus on recent emergency 2020-05-01 2007-02-02 2020-08-13 Get this from a library!

I am also particularly proud over the very high quality and creative thinking infrastructure based on the world's most powerful neutron source.

The DD110.5MB is a unique in that it uses four beams directed at a central hybrid target to produce the high thermal neutron flux available for a moderated DD fusion neutron source. 14.1 MeV Neutron Sources Thermal neutrons are produced with an 241 Am-Be neutron source (148 GBq) at the center of a graphite pile.
