In this study, the scintillation and optical properties of pure and silver doped potassium chloride (KCl:Ag) single crystals were reported. Pure and doped KCl bulk single crystals with a good optical quality and free from cracks were grown from the melt using Czochralski technique. Different analysis methods were used to study the optical and scintillation properties of the grown crystals. The ...

The use and detection of radiotracers in organic and biological chemistry has benefitted from advances in the efficiency and sophistication of both the chromatographic and the radioactive detection techniques. As a result, the chromatographic separation of radiolabeled compounds, sometimes referred to as “radiochromatography,” is now carried out in many laboratories throughout the world. The ba...

This work examines the potential use of two scintillation detectors for in-situ measurements of alpha and beta particles at various depths in soil. Use of an organic (plastic) scintillator was investigated for beta-particle measurements and a ZnS(Ag) inorganic scintillator was investigated for alpha-particle measurements. Each detector was connected to a photomultiplier tube by varying light-gu...

Abstract This article presents the fundamentals and an overview of optical-fiber-based scintillation detectors, which consist a scintillator optical fiber light guide. type detector is preferentially used in special applications. In these applications, only probe placed severe environment, while photodetector stays mild environment. Additionally, should not disturb irradiated field. As examples...

Abstract Detectors for direct dark matter search using noble gases in the liquid phase as a detection medium need to be coupled liquefaction, purification and recirculation systems. A dedicated cryogenic system has been assembled operated at INFN-Naples laboratory with aim liquefy purify argon used an active target detectors study scintillation ionization signals detected by large SiPM arrays. ...

We propose that neutrino-proton elastic scattering, n1p→n1p , can be used for the detection of supernova neutrinos in scintillator detectors. Though the proton recoil kinetic energy spectrum is soft, with Tp .2En /M p , and the scintillation light output from slow, heavily ionizing protons is quenched, the yield above a realistic threshold is nearly as large as that from n̄e1p→e1n . In addition,...

We have examined long term changes in signal amplitude gain, energy resolution and detection efficiency for the active components of the PIBETA detector system. Beam defining plastic scintillation counters were operated in a ∼ 1 MHz stopped π + beam for a period of 297 days, accumulating radiation doses of up to 2 · 10 6 rad. Detectors in the charged particle tracking system—a pair of cylindric...

We present the design and analysis of a new gamma ray spectrometer for planetary science that uses an array of CdZnTe detectors to achieve the detection efficiency needed for orbital measurements. The use of CdZnTe will provide significantly improved pulse height resolution relative to scintillation-based detectors, with commensurate improvement in the accuracy of elemental abundances determine...
