Scintillator

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.

The scintillator material in the IV was less dense than the buffer fluid by about 0.1% with the original DMP concentration of 5 g/L; this resulted in a slight upward buoyancy force on the IV, implying the need of thin, low-background ropes made of ultrahigh density polyethylene to hold the nylon vessels in place.
In scintillators, the number of emitted photons per unit energy differs according to the excitation energy, and such a relation is called the energy nonproportional response of a scintillator, or simply nonproportionality.
The pilot measurement conducted with the J-PET detector demonstrated the possibility of identifying candidates of annihilation photons interactions in the plastic scintillator strips by means of the time over threshold measure of deposited energy and angular dependencies between relative azimuthal angles of [gamma] interaction points specific to event spatial topology.

In CT, the light yield of the scintillators has to be as high as possible, the frequently used scintillator [Gd.sub.2][O.sub.2]S:Pr has a light yield of some 40000 ph/MeV.
However, the induced current of the solar cell can be considerably improved by coupling it to a CsI(Tl) scintillator. The electric current generated by solar cells has been enhanced by improving the spectral response of the solar cells and enlarging their sensitive area [8].
