The neutron moderation theory, taking into account a moderating medium temperature

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2017
In this paper, in the framework of the gas model, based on the solution of the kinematic problem of the neutron elastic scattering on the nucleus in the “L” system in the general case, that is, when prior to the scattering not only the neutron, but also

A new thermography using inelastic scattering analysis of wavelength-resolved neutron transmission imaging

open access: yesScientific Reports, 2023
Thermography using energy-dependent neutron transmission imaging can non-invasively and non-destructively visualize a real-space distribution of interior temperatures of a material in a container.

Influence of the main neutron absorbers poisons coupled to the Point Kinetics model by the Rosenbrock’s method

open access: yesBrazilian Journal of Radiation Sciences, 2022
In this work, the Neutron Point Kinetics equations are solved for six groups of delayed neutron precursors and different types of ramp reactivity, considering the temperature effects by the Rosenbrock’s method, to verify the methodology. Furthermore, the

Molecular dynamics decomposition of temperature-dependent elastic neutron scattering by a protein solution [PDF]

open access: yes, 2003
Molecular dynamics simulations are performed of bovine pancreatic trypsin inhibitor in a cryosolution over a range of temperatures from 80 to 300 K and the origins identified of elastic dynamic neutron scattering from the solution. The elastic scattering

Magnetic and electric properties of bismuth ferrite lead titanate ceramics [PDF]

open access: yes, 2010
Solid solutions of multiferroic BiFeO3 doped with ferroelectric PbTiO3 (BFPT) can be prepared by conventional mixed oxide processing to produce a range of polycrystalline ceramics ranging throughout the xBiFeO3 - (1-x)PbTiO3 series. Sintered ceramics are

Enzyme dynamics and activity: timescale dependence of dynamical transitions in glutamate dehydrogenase solution [PDF]

open access: yes, 1999
We have examined the temperature dependence of motions in a cryosolution of the enzyme glutamate dehydrogenase (GDH) and compared these with activity.

Fusion Based Neutron Sources for Security Applications: Neutron Techniques [PDF]

open access: yes, 2014
The current reliance on X-Rays and intelligence for na- tional security is insufficient to combat the current risks of smuggling and terrorism seen on an international level. There are a range of neutron based security techniques which have the potential

Investigation on the heat resistance of neutron shielding materials for reactor cavity

open access: yesHe jishu, 2021
BackgroundHigh temperature neutron shielding of the reactor cavity in the third generation nuclear power plant requires a high temperature resistant shielding material, but there is no suitable material that meets the design requirements in the market ...

Numerical simulation of neutron radiation effects in avalanche photodiodes [PDF]

open access: yes, 2000
A new one-dimensional (1-D) device model developed for the simulation of neutron radiation effects in silicon avalanche photodiodes is described. The model uses a finite difference technique to solve the time-independent semiconductor equations across a ...
