Spontaneous scalarization in proto-neutron stars

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Proto-neutron stars are born when a highly evolved and massive star collapses under gravity. In this paper, we investigate the spontaneous scalarization in proto-neutron stars.

Finite-temperature equation of state with hyperons [PDF]

open access: yesEPJ Web of Conferences, 2022
We present the novel finite-temperature FSU2H* equation-of-state model that covers a wide range of temperatures and lepton fractions for the conditions in proto-neutron stars, neutron star mergers and supernovae.

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

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.

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

Decoupling of a neutron interferometer from temperature gradients

open access: yesReview of Scientific Instruments, 2016
Neutron interferometry enables precision measurements that are typically operated within elaborate, multi-layered facilities which provide substantial shielding from environmental noise. These facilities are necessary to maintain the coherence requirements in a perfect crystal neutron interferometer which is extremely sensitive to local environmental ...

Neutron matter at finite temperature [PDF]

open access: yesNuclear Physics A, 2008
We calculate the neutron matter equation of state at finite temperature based on low-momentum two- and three-nucleon interactions. The free energy is obtained from a loop expansion around the Hartree-Fock energy, including contributions from normal and anomalous diagrams.

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 ...

Development of a powerful UCN source at PNPI's WWR-M reactor [PDF]

open access: yesEPJ Web of Conferences, 2019
The WWR-M reactor at PNPI is planned to be equipped with a high-flux source for ultracold neutrons (UCNs). The method of UCN production is based on neutron conversion in superfluid helium, exploiting the particular qualities of that quantum liquid.
