Neutrons production on the IPHI accelerator for the validation of the design of the compact neutron source SONATE [PDF]
EPJ Web of Conferences, 2020 We aim at building a compact accelerator-based neutron source (CANS) which would provide a thermal neutron flux on the order of 4x1012 n.s-1.cm-2.sr-1. Such a brilliance would put compact neutron sources on par with existing medium flux neutron research ...

Eurasian Journal of Physics and Functional Materials, 2021 Neutrons are produced in accelerators by irradiating heavy targets with an electron or proton beam. Produced neutrons are of high energy. The purpose of our work is optimization the neutron flux by MCNP-6 code for production the thermal neutron flux ...

Measurement of the neutron flux at spallation sources using multi-foil activation [PDF]
Nuclear Instruments and Methods in Physics Research Section A : Accelerators, Spectrometers, Detectors and Associated Equipment, 2018 Activation analysis is used in this work to measure the flux of a fast neutron beamline at a spallation source over a wide energy spectrum, extending from thermal to hundreds of MeV.

Tolerance Flux of Thermal Neutrons [PDF]
Nature, 1949 THE danger of neutrons on the human body arises from two factors : the slowing down of fast neutrons and the absorption of neutrons. In the case of thermal neutrons, only absorption can take place, either in hydrogen to form a deuteron with emission of a 2.2-MeV. γ-ray, or by nitrogen-14 to form a carbon, with the emission of a 0.7-MeV. proton.

Current compensation for material consumption of cobalt self-powered neutron detector
Nuclear Engineering and Technology, 2020 Co Self-Powered Neutron Detector (SPND) is confronted with the problem of material consumption, which causes the response current can neither reflect the change of neutron flux in time nor be proportional to the neutron flux.

Journal of Radiation Research and Applied Sciences, 2018 Comparative studies for conversion of the fuel from high enriched uranium (HEU) to low enriched uranium (LEU) in the reactor (MNSR) were performed using DRAGON code deterministic. In this work the HEU fuel (UAl4-Al, 90% enriched with Al-clad) and LEU (12.
