Neutron features at the UPM neutronics hall [PDF]
Applied 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 241AmBe source were measured at various source-to-detector ...

Neutron-mirror neutron mixing and neutron stars [PDF]
The 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 $$n-n'$$

Neutron–Mirror-Neutron Oscillation and Neutron Star Cooling
Physical 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.

IEEE 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]
Nuclear 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 ...

Neutron-neutron and neutron-photon correlations withFREYA [PDF]
EPJ Web of Conferences, 2017 For many years, the state of the art for modeling fission in radiation transport codes has involved sampling from average distributions. However, in a true fission event, the energies, momenta and multiplicities of emitted particles are correlated. The FREYA (Fission Reaction Event Yield Algorithm) code generates complete fission events. Event-by-event

Search for Neutron-to-Hidden-Neutron Oscillations in an Ultracold Neutron Beam
Physical Review Letters, 2023 Models that postulate the existence of hidden sectors address contemporary questions, such as the source of baryogenesis and the nature of dark matter. Among the possible mixing processes, neutron-to-hidden-neutron oscillations have been repeatedly tested with ultra-cold neutron storage and passing-through-wall experiments in the range of small ($δm<
