High-Efficiency Resonant RF Spin Rotator with Broad Phase Space Acceptance for Pulsed Polarized Cold Neutron Beams [PDF]

open access: yes, 2007
We have developed a radio-frequency resonant spin rotator to reverse the neutron polarization in a 9.5 cm x 9.5 cm pulsed cold neutron beam with high efficiency over a broad cold neutron energy range. The effect of the spin reversal by the rotator on the

Model-Based Deep Learning Algorithm for Pulse Shape Discrimination in High Event Rates [PDF]

open access: yesEPJ Web of Conferences, 2023
Pulse shape discrimination (PSD) is at the core of radioactive particles monitoring. Conventional PSD methods are geared towards low event rates, and struggle in the presence of pileups resulting from high rate.

Double neutron/proton ratio of nucleon emissions in isotopic reaction systems as a robust probe of nuclear symmetry energy [PDF]

open access: yes, 2005
The double neutron/proton ratio of nucleon emissions taken from two reaction systems using four isotopes of the same element, namely, the neutron/proton ratio in the neutron-rich system over that in the more symmetric system, has the advantage of ...

Neutrons and Gamma-Ray Dose Calculations in Subcritical Reactor Facility Using MCNP

open access: yesAtoms, 2016
In nuclear experimental, training and teaching laboratories such as a subcritical reactor facility, huge measures of external radiation doses could be caused by neutron and gamma radiation.

Effect of a Moving Mirror on the Free Fall of a Quantum Particle in a Homogeneous Gravitational Field

open access: yesQuantum Reports, 2022
We investigate the effect of time-dependent boundary conditions on the dynamics of a quantum bouncer—a particle falling in a homogeneous gravitational field on a moving mirror.

Benchmark shielding calculations for fusion and accelerator-driven sub-critical systems

open access: yesFrontiers in Energy Research, 2023
We conducted benchmark calculations of neutron-shielding experiments for fusion applications such as (1) Neutron spectra in iron shields with 14 MeV neutrons; and (2) Leakage neutron spectra from various sphere piles by 14 MeV neutrons, and for ...

Initial data for black hole-neutron star binaries, with rotating stars [PDF]

open access: yes, 2016
The coalescence of a neutron star with a black hole is a primary science target of ground-based gravitational wave detectors. Constraining or measuring the neutron star spin directly from gravitational wave observations requires knowledge of the ...

Survey of radiation monitoring system for magnetic confinement fusion device

open access: yesHe jishu, 2023
The nuclear fusion reaction using deuterium and tritium fuel produces a large number of neutrons, γ rays and activation products, which have an impact on the radiation safety of people and the environment.

Enhanced Production of Neutron-Rich Rare Isotopes in Peripheral Collisions at Fermi Energies [PDF]

open access: yes, 2003
A large enhancement in the production of neutron-rich projectile residues is observed in the reactions of a 25 MeV/nucleon 86Kr beam with the neutron rich 124Sn and 64Ni targets relative to the predictions of the EPAX parametrization of high-energy ...
