Organic–inorganic hybrid perovskite scintillators for mixed field radiation detection

InfoMat, 2022
Sensitive and fast detection of neutrons and gamma rays is vital for homeland security, high‐energy physics, and proton therapy. Fast‐neutron detectors rely on light organic scintillators, and γ‐ray detectors use heavy inorganic scintillators and ...

A propelling neutron star in the enigmatic Be-star $\gamma$~Cassiopeia [PDF]

, 2016
The enigmatic X-ray emission from the bright optical star, $\gamma$ Cassiopeia, is a long-standing problem. $\gamma$ Cas is known to be a binary system consisting of a Be-type star and a low-mass ($M\sim 1\,M_\odot$) companion of unknown nature orbiting ...

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories

Advanced Engineering Materials, EarlyView.
Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...

Investigating Thermal and Fast Neutron Shielding Properties of B4C, B2O3, Sm2O3, and Gd2O3 doped Polymer Matrix Composites using Monte Carlo Simulations

Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2021
In this study, thermal (2.53*10-8 MeV) and fast (2 MeV) neutron total macroscopic cross-sections of paraffin, polycarbonate, and polyester matrix polymers doped with B4C, B2O3, Sm2O3, and Gd2O3 (at weight percentages of 5%, 10%, 15%, 20%, and 25%) were ...

Effects of Neutron Irradiation on Pinning Force Scaling in State-of-the-Art Nb3Sn Wires

, 2013
We present an extensive irradiation study involving five state-of-the-art Nb3Sn wires which were subjected to sequential neutron irradiation up to a fast neutron fluence of 1.6 * 10^22 m^-2 (E > 0.1 MeV).

Phenomenological and Physically Based Modeling of Flow Stress and Strengthening Mechanism of Inconel 718

Advanced Engineering Materials, EarlyView.
Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.

Radiation shielding for a nuclear fusion device with inertial electrostatic confinement

Brazilian Journal of Radiation Sciences, 2022
In an inertial electrostatic confinement nuclear fusion device, IECF, thermal neutron population is created near the neutron shielding that is proportional to the fast neutrons generation rate; nevertheless, this proportionality varies with the ...
