A new scintillator for liquid scintillation counting

The International Journal of Applied Radiation and Isotopes, 1967
Abstract This report describes the results of investigations carried out with a new scintillator: 2-(4′-t-Butylphenyl)-5-(4″-biphenylyl)-1,3,4-oxdiazole (Butyl-PBD). Counting efficiencies and background counts of variously quenched toluene and dioxane systems containing Butyl-PBD have been compared with similar systems containing PPO and DM-POPOP as ...

Scintillation Mechanisms in Inorganic Scintillators

2016
Details of energy transfer phenomena and scintillation mechanisms in luminescent media excited by ionizing radiation are discussed in this chapter. The sequence of relaxation of electronic excitations is described: creation of electron-hole pairs, energy transfer to emitting centers of interest and quantum efficiency of these luminescence centers.

Scintillation response of organic and inorganic scintillators

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1999
Abstract A method to evaluate the scintillation response of organic and inorganic scintillators to different heavy ionizing particles is suggested. A function describing the rate of the energy consumed as fluorescence emission is derived, i.e., the differential response with respect to time.

Scintillation response of Y3Al5O12:Pr3+ single crystal scintillators

Radiation Measurements, 2013
Abstract In this paper we present the photoluminescence (PL) and scintillation response of Pr 3+ -doped Y 3 Al 5 O 12 (YAG:Pr) single crystals grown by the Czochralski method with different Pr 3+ concentrations of 0.16, 0.33, and 0.65 mol%. PL spectra and decay curves were measured for both the fast 5d → 4f and slow 4f → 4f emissions.

Scintillation mechanism and efficiency of ternary scintillator thin films

IEEE Transactions on Nuclear Science, 2002
The scintillation mechanism of ternary plastic scintillators, excited by ions, was studied in order to correlate the scintillation efficiency as a function of the thickness to the energy transfer process between the light emitters embedded in the polymer.

Scintillation Proximity Assay

Current Protocols in Neuroscience, 1999
AbstractScintillation proximity assay technologies provide a rapid non‐separation method to measure common biological interactions. This unit identifies potential uses of the technology for the measurement of receptor‐ligand binding, cAMP accumulation, protease activity and cellular uptake.

Polychromatic scintillation

Journal of the Optical Society of America A, 2003
A formula to compute the index of stellar scintillation detected with a finite spectral bandpass and with arbitrary aperture is derived in the limit of weak perturbations. It also applies to differential scintillation (relative fluctuations of light intensity in a pair of apertures), where the effect of finite bandpass turns out to be significant.

Tracking with Scintillating Fibres [PDF]

, 1989
At the end of 1987, the upgraded UA2 experiment [1] took its first data at the SPS pp collider. The scintillating fibre detector (SFD) [1–3] forms the outer part of a new detector, which fits inside the central calorimeter and provides tracking and electron identification.
