Equilibria and oscillations of magnetised neutron stars

, 2010
We investigate equilibrium configurations and oscillation spectra of neutron stars,modelled as rotating magnetised fluid bodies in Newtonian gravity. We also explorethe idea that these model neutron stars could have dynamics analogous to rigid-bodyfree ...

Time-resolved fast-neutron imaging with a pulse-counting image intensifier [PDF]

, 2006
A new imaging method that combines high-efficiency fast-neutron detection with sub-ns time resolution is presented. This is achieved by exploiting the high neutron detection efficiency of a thick scintillator and the fast timing capability and ...

Neutron activation analysis of plantinum converter and furnace mattes using a D-T sealed tube neutron generator [PDF]

, 2013
Neutron activation analysis (NAA) has been applied to furnace matte and converter matte samples with the objective of studying the natural variation in the elemental composition of the samples, with a view to characterize the samples for their source of ...

Measurement of fusion neutron yields in laser–cluster fusion experiments using binomial statistics

Nuclear Fusion
Accurate neutron-yield measurement is essential for fusion plasma diagnostics. In laser-driven fusion experiments, short-pulse quasi-monoenergetic neutrons can overlap within a narrow time-of-flight (TOF) window, leading to an underestimation of the ...

The effect of scattered neutrons on the ion temperature measurement with different line-of-sight on the SGIII laser facility

AIP Advances, 2019
Two neutron time-of-flight (nToF) detectors have been employed to measure the neutron time-of-flight spectrum in different lines-of-sight, i.e., at the equator plane and the south pole, on Shenguang-III (SG-III) laser facility.

Helium effect on temperature-displacement rate equivalence in radiation-induced swelling of iron: A study by improved stochastic cluster dynamics

Nuclear Materials and Energy
In nuclear energy systems, understanding material behavior (e.g., swelling) under irradiation is critical for ensuring long-term stability and safety. While direct neutron irradiation experiments pose significant challenges, ion irradiation serves as an ...

Core Optimization for Extending the Graphite Irradiation Lifespan in a Small Modular Thorium-Based Molten Salt Reactor

Journal of Nuclear Engineering
The lifespan of core graphite under neutron irradiation in a commercial molten salt reactor (MSR) has an important influence on its economy. Flattening the fast neutron flux (≥0.05 MeV) distribution in the core is the main method to extend the graphite ...
