Velocity-space sensitivity and tomography of scintillator-based fast-ion loss detectors

Plasma Physics and Controlled Fusion, 2018
A simple model for the instrument function of scintillator-based fast-ion loss detectors (FILD) has been developed which accounts for the orbit trajectories in the 3D detector geometry and for the scintillator response.

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

High‐Security X‐Ray Imaging Encryption Based on Irreversible Acid‐Responsive Radioluminescence Memory Scintillator

Advanced Science, EarlyView.
An irreversible acid‐responsive radioluminescence memory scintillator, Zn1.3Ga1.4Ge0.3O4:Cr3+@Zn2GeO4:Eu3+ (ZGGO@ZGO), is developed in this work. The engineered dual‐layer security system composed of ZGGO@ZGO and ZGO achieves a combined effect of visual misdirection and sequential logic gates requiring acid treatment and CCD detection, significantly ...

Halide‐Exchange Arrest Enables Reabsorption‐Free CsPbCl3/CsPbI3 Perovskite Core/Shell Nanocrystals

Advanced Science, EarlyView.
Achieving large Stokes shifts in perovskite nanocrystals is challenging due to halide mobility that disrupts stable core–shell structures. Using CdCl2 passivation, this work stabilizes CsPbCl3/CsPbI3 heterostructures, yielding a ≈1.2 eV Stokes shift, high quantum yield, and fast exciton transfer, enabling reabsorption‐free emitters for advanced ...

Study on the Characteristics of a Scintillator for Beta-ray Detection using Epoxy Resin

EPJ Web of Conferences, 2017
A thin plate of a plastic scintillator for detecting a beta-ray was developed. The plastic scintillator was made using epoxy resin and organic scintillators such as 2.5-diphenyloxazole (PPO) and 1,4-bis [5-phenyl-2-oxazole] benzene (POPOP).
