scintillator

[′sint·əl‚ād·ər]
(nucleonics)
A material that emits optical photons in response to ionizing radiation.

Scintillator

 

a luminophor in which the flashes of light known as scintillations occur under the action of ionizing radiation. Among the many substances that are scintillators are inorganic crystals, such as zinc sulfide and sodium iodide; organic crystals, such as anthracene and stilbene; solutions of plastics; and inert gases. Scintillators used in scintillation counters should be transparent to their own radiation.

Technavio's analysts forecast the global scintillator market to grow at a CAGR of 5.
This results suggest that the replacement of liquid scintillators by plastic scintillators for applications challenged by the well known problems of liquids such as toxicity, flammability, high freezing points, among others is now possible [3, 4].
It is superior to conventional scintillators in terms of luminescence, refractive index and density.
This then allows the tuning of the wavelength of light emission in the 328-375 nm region when OMMT and HNTs are added to amine-cured epoxy resins to overlap with the dye absorption spectrum in plastic scintillators based on this polymer.
Scintillators are materials that, when struck by photons of higher energy, such as gamma rays, capture this energy and release it as photons of lower energy, usually visible light.
Nonetheless, in 2005, this experiment, called KamLAND (short for Kamioka Liquid Scintillator Anti-Neutrino Detector), provided the first glimpse of geoneutrinos and a first approximation of uranium and thorium's contribution to the Earth's heat.
Scintillators convert detected X-ray photons into visible light.
These new detectors can be used for direct, detection and spectrometry of beta particles and low energy X-rays, or, when coupled with scintillators, for sensing gamma rays and higher energy X-rays.
Plastic scintillators, in contrast, are made of a plastic to which fluor is added so that the material has the ability to emit light, or scintillate, when hit by radiation.
The material described in this document is in connection with this development; In particular with the construction of a scintillating fiber tracker, a particle detector based on the principle of plastic fiber scintillators.
