Am-be neutron source

The neutron source used was a sealed 241Am-Be(α,n) source (model AMN22, serial number AMN1000/1096) owned by the NPL, which had a nominal activity of 37 GBq (1 Ci). It is in an X3 capsule (outer length 31 mm, outer diameter 22.4 mm) a type currently manufactured by QSA Global. The source was chosen for its long half-life and stable decay process, and also because it is An Am/Be neutron source, installed recently at the Rajshahi University, is described. Neutron flux mapping was done using the nuclear reactions (197)Au(n,gamma)(198)Au, (113)In(n,gamma)(114m)In, (115)In(n,n'gamma)(115m)In and (58)Ni(n,p)(58)Co. Safe, cost-effective and homemade design of diminutive Am–Be neutron source is obtained by combining an alpha source as an active component and a disk of light metal as a target. 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. This is similar to the published spectra of Po-210Be(alpha, neutron) sources. In neutron C/O and neutron porosity logs, fast neutrons, usually generated by a deuterium-tritium (D-T) accelerator or Am–Be isotopic sources, are used.

Radiation Protection in the 2000s - Julkari

With its more intense, brighter source of neutrons and world-class instrument suite, SNS provides the neutron scattering community with unprecedented research opportunities. The facility allows for measurements of greater sensitivity, higher speed, and higher resolution and in more complex sample environments than have been possible at other neutron facilities around the world. The present work targeted the study of the isomeric state formation in (n,n ' ) and (n,p) reactions using the spectral emission of an 241 Am-Be neutron source which favors the (neutron, nucleon) reactions over the (n, γ) and (n,2n) ones.

An Am/Be neutron source, installed recently at the Rajshahi University, is described. Neutron flux mapping was done using the nuclear reactions (197)Au (n,gamma) (198)Au, (113)In (n,gamma) 241Am–Be(α,n) neutron sources provide one of the most commonly used neutron fields for routine calibration of neutron sensitive devices. The neutron energy distribution of the IRSN standard 241Am–Be source was measured in the energy region above 1.65 MeV using a BC501A proton-recoil liquid scintillator. A neutron source is any device that emits neutrons, irrespective of the mechanism used to produce the neutrons. Neutron sources are used in physics, engineering, medicine, nuclear weapons, petroleum exploration, biology, chemistry, and nuclear power.
