Solar Cycle Variations of GPS Amplitude Scintillation for the Polar Region

Space Weather, 2020
Global Positioning System (GPS) L1 amplitude data, obtained using the Canadian High Arctic Ionospheric Network (CHAIN) during the period 2008–2018, is used to study the seasonal and solar cycle dependence of high‐latitude amplitude scintillation.

The Sensitization of Scintillation in Polymeric Composites Based on Fluorescent Nanocomplexes

Nanomaterials, 2021
The sensitization of scintillation was investigated in crosslinked polymeric composite materials loaded with luminescent gold clusters aggregates acting as sensitizers, and with organic dye rhodamine 6G as the emitting species.

Scintillation reduction by use of multiple Gaussian laser beams with different wavelengths [PDF]

, 2006
We study the scintillation index of N partially overlapping collimated lowest order Gaussian laser beams with different wavelengths in weak atmospheric turbulence. Using the Rytov approximation we calculate the initial beam separation that minimizes the longitudinal scintillation.

A Model of Nuclear Recoil Scintillation Efficiency in Noble Liquids [PDF]

Astropart.Phys.30:12-17,2008, 2007
Scintillation efficiency of low-energy nuclear recoils in noble liquids plays a crucial role in interpreting results from some direct searches for Weakly Interacting Massive Particle (WIMP) dark matter. However, the cause of a reduced scintillation efficiency relative to electronic recoils in noble liquids remains unclear at the moment.

A Python package for fast GPU‐based proton pencil beam dose calculation

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Open‐source GPU‐based Monte Carlo (MC) proton dose calculation algorithms provide high speed and unparalleled accuracy but can be complex to integrate with new applications and remain slower than GPU‐based pencil beam (PB) methods, which sacrifice some physical accuracy for sub‐second plan calculation.

Amplitude scintillation detection with geodetic GNSS receivers leveraging machine learning decision tree

Satellite Navigation
The amplitude scintillation detection is typically achieved by using the scintillation index generated by dedicated and costly ionospheric scintillation monitoring receivers (ISMRs).

Luminescence and scintillation properties of CsI: A potential cryogenic scintillator [PDF]

physica status solidi (b), 2015
Caesium iodide is one of the most extensively studied scintillators. Here, we present X‐ray luminescence spectra, scintillation light output and decay curves as a function of temperature, from room temperature down to below 10 K. Features of the observed intrinsic luminescence are explained in terms of radiative recombination of on‐ and off‐center STE.

Characterization and Optimization of Vesicle Properties in bioPISA: from Size Distribution to Post‐Assembly Loading

Advanced Biology, EarlyView.
The paper explores the creation and characterization of vesicles through biocatalytic Polymerization‐Induced Self‐Assembly (bioPISA), focusing on achieving size uniformity using centrifugation techniques. It examines the effects of stirring speed on vesicle morphology and analyses the internal polymer‐rich structure using fluorescence correlation ...

Highly Luminous Scintillating Nanocomposites Enable Ultrafast Time Coincidence Resolution for γ‐rays Detection with Heterostructured Multilayer Scintillators

Advanced Functional Materials, EarlyView.
A scintillating polymeric composites loaded with hafnia nanoparticles is engineered to obtain a highly luminous material, thus achieving a 400% improvement of the scintillation yield under soft X‐rays. The nanocomposite is employed to realize a multilayer heterostructured prototype scintillator than enable for ultrafast time coincidence resolution in ...

Cherenkov and Scintillation Light Separation Using Wavelength in LAB Based Liquid Scintillator [PDF]

Journal of Instrumentation. 14 (2019) 1-15, 2018
Linear alkyl benzene (LAB) has in recent years been used as a solvent for PPO in large-scale scintillation detectors, like Daya Bay and SNO+. The combination has several nice properties, including high light yield, good materials compatibility, and excellent pulse shape discrimination.
