Neutron features at the UPM neutronics hall [PDF]

open access: yesApplied Radiation and Isotopes, 2012
The neutronics hall of the Nuclear Engineering Department at the Polytechnical University of Madrid has been characterized. The neutron spectra and the ambient dose equivalent produced by an (241)AmBe source were measured at various source-to-detector distances on the new bench.

Neutron-mirror neutron mixing and neutron stars [PDF]

open access: yesThe European Physical Journal C, 2021
AbstractThe oscillation of neutron n into mirror neutron $$n'$$ n ′ , its mass degenerate partner from dark mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter. In quark stars $$n-n'$$

Towards automatic CAD defeaturing for fusion neutronics

open access: yes
A typical neutronics simulation process may involve the conversion of a detailed CAD model into a modified analysis model. This conversion process almost always requires prior defeaturing or modification of the detailed model’s geometry, whether it is ...

Neutron–Mirror-Neutron Oscillation and Neutron Star Cooling

open access: yesPhysical Review Letters, 2022
It was pointed out in a recent paper that the observed cooling rate of old, cold neutron stars (NS) can provide an upper limit on the transition rate of neutron to mirror neutron ($n-n'$). This limit is so stringent that it would preclude any discovery of $n \to n'$ oscillation in the current round of terrestrial searches for the process.

A MLEM-TV-MRP Algorithm for Fast Neutron Computed Tomography Reconstruction of High Statistical Noise and Sparse Sampling

open access: yesIEEE Access, 2020
Fast neutron computed tomography (FNCT) generally needs a longer measurement time because of low source strength and low detection efficiency. In order to reduce measurement time, methods of reducing single measurement time and the numbers of projection ...

Verification and application of SuperMC3.3 to lead-bismuth-cooled fast reactor [PDF]

open access: yesNuclear Technology and Radiation Protection, 2019
Lead-cooled fast reactors have multilayered designs and large internal temperature differences, which cause challenges in simulating reactor physics. SuperMC, a large-scale integrated software system for neutronics design, is inherently able to address ...
