Ultracold neutron detection with 6Li-doped glass scintillators, NANOSC: a fast ultracold neutron detector for the nEDM experiment at the Paul Scherrer Institute [PDF]

open access: yes, 2016
This paper summarizes the results from measurements aiming to characterize ultracold neutron detection with 6Li-doped glass scintillators. Single GS10 or GS20 scintillators, with a thickness of 100-200 micrometer, fulfill the ultracold neutron detection requirements with an acceptable neutron-gamma discrimination.

Effect of Scintillation Cocktail and Quenching Calibration Method on Measurement of 55Fe by LSC

open access: yesHe huaxue yu fangshe huaxue
In order to optimize the measurement conditions of 55Fe by liquid scintillation counting, the effect of three kinds of commercial scintillation cocktail and two efficiency correction methods on LSC measurements of 55Fe was tested.

Liquid Scintillator Time Projection Chamber Concept

open access: yes, 2012
Results are presented from a small-scale experiment to investigate the use of room temperature organic liquid scintillators as the active medium for a time projection chamber (TPC). The optical properties of liquid scintillators have long been known, but

Radon emanation rate measurements using liquid scintillation counting [PDF]

open access: yesJINST 20 P01020 (2025)
This article describes a radon emanation measurement technique using liquid scintillator counting. A model for radon loading and transport is described, along with its calibration. Detector background and blank have been studied and quantified. The Minimal detectable activity has been determined for the counting setup using a toy Monte Carlo simulation.

Scintillation characteristics of the EJ-299-02H scintillator [PDF]

open access: yesarXiv, 2023
A study of the dead layer thickness and quenching factor of a plastic scintillator for use in ultracold neutron (UCN) experiments is described. Alpha spectroscopy was used to determine the thickness of a thin surface dead layer, and the relative light outputs from the decay of $^{241}$Am and Compton scattering of electrons were used to extract the ...

Use of Silicon Photomultipliers in ZnS:6LiF scintillation neutron detectors: signal extraction in presence of high dark count rates [PDF]

open access: yes, 2014
We report on the possibility of using Silicon Photomultipliers (SiPMs) to detect the scintillation light from neutron conversion in ZnS:6LiF scintillators. The light is collected by wavelength-shifting fibers embedded into the scintillator. The difficulty of extracting neutron signals in the presence of high dark count rates of the SiPMs is addressed ...

A Compton polarimeter using scintillators read out with MPPCs through Citiroc ASIC [PDF]

open access: yes, 2019
In recent years, a number of purpose-built scintillator-based polarimeters have studied bright astronomical sources for the first time in the hard X-ray band (tens to hundreds of keV). The addition of polarimetry can help data interpretation by resolving model-dependent degeneracies. The typical instrument approach is that incident X-rays scatter off a

Combined pyrolysis and radiochemical gas chromatography for studying the thermal degradation of polymers [PDF]

open access: yes, 1968
Pyrolysis gas chromatography and radioactive tracer techniques have been used independently to study the thermal degradation of polymers. In these laboratories the two techniques have been combined to elucidate some of the mechanisms of the thermal ...

Measurement of the scintillation time spectra and pulse-shape discrimination of low-energy beta and nuclear recoils in liquid argon with DEAP-1 [PDF]

open access: yes, 2016
The DEAP-1 low-background liquid argon detector was used to measure scintillation pulse shapes of electron and nuclear recoil events and to demonstrate the feasibility of pulse-shape discrimination (PSD) down to an electron-equivalent energy of 20 keV.
