Reconstruction of a 6-MeV bremsstrahlung spectrum by multi-layer absorption based on LiF:Mg, Cu, P

“…The values of the energy absorption coefficients µ e for water are about 0.0165 cm −1 to 0.0330 cm −1 in the energy range from 0.1 MeV to 10 MeV. [9] Besides, the thickness of the equivalent aquatic layer is 50 µm, so the deposited energy ∆ε x in the thin aquatic layer approximates to E x µ e (E x )d, where d is the thickness of the thin aquatic layer, E x is the energy of incident photons. The mass ∆m of the thin aquatic layer is ρSd, where ρ is the mass density of water, S is the cross-sectional area.…”

[8] M i j means the absorbed dose in the TLD detector when the unit fraction of bremsstrahlung with energy E j between energy interval (E j − 1 2 ∆E j , E j + 1 2 ∆E j ) transmitted through a medium with a thickness of x i .…”

Optimization of a microreactor core's dimensions using metaheuristic methods

“…The microscopic cross-section values of transport σtr, fission σf, radiative capture σγ, scattering to another group σsg'g and ν for 235 U and 238 U, for each of the 4 energy groups, were extracted directly from Argonne National Laboratory publications [5].…”
