Designing an Am-Be miniature neutron source
Background: Miniature neutron sources with high neutron flux have abundant applications in medicine, industry and researches. The most important general characteristic of miniature neutron sources is their diameter which is 3mm in average. In this research, we have surveyed and designed an Am-Be miniature neutron source fabrication. Materials and Methods: This investigation resulted in creation...
متن کاملAsphalt and Paraffin Scale Deposit Measurement by Neutron Back Diffusion Using 252Cf and 241Am-Be Sources
Hydrocarbon deposits, often found in oil or polymer industries, are very difficult to detect by the usual inspection techniques of gamma radiography or x-ray radiography methods. The density and atomic number of pipe walls are much higher than that of the scale, therefore, most of the attenuation of gamma rays or x-rays, takes place in the iron, and only a negligible fraction in the scale. This...
متن کاملAn Optimum Landmine Detection System Using Polyethylene Moderator and 241Am-Be as a Neutron Source
In this paper an optimized moderating structure using an 241Am-Be neutron source for detecting landmines (using the PGNAA method) has been investigated by experiment. The experimental set up composed of a Pb cylindrical shell enclosing the neutron source, embedded in a fixed size High-density polyethylene (HDPe) cylinder with the variable thickness of the upper and lower moderator. The optimizi...
متن کاملstudy of neutron yield for the 241am9be source
beryllium chemical combination has a considerable effect on the design and fabrication of the241am9be neutron source. in this investigation the beryllium combinations were studied as a generator ofneutrons with various mass percentage, and the neutron yields were also calculated using the results of thealice and srim codes calculations per unit incident charge. the neutron yields of beryllium ...
