Development and Verification of Hexagonal Quasi-diffusion Code Based on Variational Nodal Method

Yuanzineng kexue jishu, 2023
New type reactors usually adopt advanced fuel types and more anisotropic fuel arrangements, the neutron spectrum is very different from that of pressurized water reactor, and the neutron anisotropy is stronger.

Non-classical transport with angular-dependent path-length distributions. 2: Application to pebble bed reactor cores

, 2013
We describe an analysis of neutron transport in the interior of model pebble bed reactor (PBR) cores, considering both crystal and random pebble arrangements.

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

A field determination method of D-T neutron source yields based on oxygen prompt gamma rays

Nuclear Engineering and Technology, 2023
A field determination method for small D-T neutron source yield based on the oxygen prompt gamma rays was established. A neutron-gamma transport equation of the determination device was developed. Two yield field determination devices with a thickness of

Numerical simulations of neutron star-black hole binaries in the near-equal-mass regime [PDF]

, 2019
Simulations of neutron star-black hole (NSBH) binaries generally consider black holes with masses in the range $(5-10)M_\odot$, where we expect to find most stellar mass black holes.

On nonlinear neutron transport equations

Journal of Mathematical Analysis and Applications, 1973
AbstractThe purpose of this paper is to investigate a class of time-dependent neutron transport equations in which the total and differential scattering cross sections are nonlinear functions of neutron density function. Sufficient conditions on the nonlinear cross sections are given to insure the existence, uniqueness and asymptotic stability of a ...

In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device

Advanced Functional Materials, EarlyView.
In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

Consideration of a ultracold neutron source in two-dimensional cylindrical geometry by taking simulated boundaries

AIP Advances, 2014
A new idea to calculate ultracold neutron (UCN) production by using Monte Carlo simulation method to calculate the cold neutron (CN) flux and an analytical approach to calculate the UCN production from the simulated CN flux was given.

Relativistic kinetic equation for Compton scattering of polarized radiation in strong magnetic field

, 2012
We derive the relativistic kinetic equation for Compton scattering of polarized radiation in strong magnetic field using the Bogolyubov method. The induced scattering and the Pauli exclusion principle are taken into account.

The Influence of Nuclear Composition on the Electron Fraction in the Post-Core-Bounce Supernova Environment [PDF]

, 1996
We study the early evolution of the electron fraction (or, alternatively, the neutron-to-proton ratio) in the region above the hot proto-neutron star formed after a supernova explosion.
