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.

In other words, bright scintillator materials are dark in storage luminescence, and vice versa.
Technavio's report, Global Scintillator Market 2016-2020, has been prepared based on an in-depth market analysis with inputs from industry experts.
It was meant to test the response of the organic plastic scintillator EJ 299-33, the same scintillator used in the in-beam experiment.
5m megapixel image sensor with a pixel pitch of 125 microns and offer a cesium iodide (CsI) or gadolinium oxysulfide (GSO) scintillator, respectively.
Scintillator materials are used to detect, and in some cases identify, gamma rays.
It produces a lot of light, and it's very transparent, but it's a safer scintillator," says SNO+ director Mark Chen.
X-rays are converted into light using a Kasei DRZ Standard, DRZ Plus, or a CsI scintillator.
Indirect conversion, shown in Figure 2, uses a scintillator material to convert the photons to light, then converts the light to an electrical signal with photodiodes, CCD, or CMOS imaging sensors.
The former enables DX-S to capture sharper images by minimizing scattering, caused by light spread in the scintillator layer.
The proton detector, a CsI scintillator, is situated on top of the storage volume; the decay protons are accelerated and focused onto it through a potential difference in the storage volume and an additional focusing coil around the detector.
To make the devices, "students taped short photomultiplier tubes to special plastic scintillator panels and carefully wrapped the whole apparatus in black electrical tape to keep out light," the Times reports.
