Characterization of 244Cm neutron sources

Applied Radiation and Isotopes, 2020
There is a need to find a replacement for the 252Cf sources currently used in Standards-based performance testing of neutron instrumentation. This is a result of its relatively short half-life, concerns about future availability and recent increases in cost.

Sensitized Triplet Exciton Generation in Nanostructured Polymer Scintillators: Toward Improved γ/Neutron Discrimination

Advanced Functional Materials, EarlyView.
Rapid γ/neutron discrimination through PSD is achieved in liquid droplet containing nanostructured polymeric scintillator where a TTA‐active dye is dissolved. The inclusion of a properly selected and dosed sensitizer metalated porphyrin enhances discrimination sensitivity and speed by doubling the density of annihilating triplets and increasing the ...

Absence of dynamic strain aging in an additively manufactured nickel-base superalloy

Nature Communications, 2018
Detrimental serrated plastic flow via dynamic strain aging (DSA) in conventionally processed nickel superalloys usually occurs during high temperature deformation.

Dynamical Analysis and Periodic Solution of a Chaotic System with Coexisting Attractors

Complexity, 2021
Chaotic attractors with no equilibria, with an unstable node, and with stable node-focus are presented in this paper. The conservative solutions are investigated by the semianalytical and seminumerical method.

Young neutron stars with soft gamma ray emission and anomalous X-ray pulsar

, 2017
The observational properties of Soft Gamma Repeaters and Ano\-malous X-ray Pulsars (SGR/AXP) indicate to necessity of the energy source different from a rotational energy of a neutron star.

Detector development for spin-echo SANS techniques using ZnS:Ag/6LiF and 6Li glass scintillators

Scientific Reports
Neutron spin-echo techniques exploit Larmor precession of the neutron spin to encode either the scattering angle or energy. These are powerful means to extend the measurable momentum transfer (Q) and energy (E) range in neutron scattering measurements ...
