The latter then rapidly de-excite by emitting scintillation light (fast component).
The avalanche of electrons also creates a great deal of scintillation light, which passes through the wire mesh.
The delayed de-excitation of those metastable impurity states again results in scintillation light (slow component).
The scintillation light produced in scintillation volume will be detected with those photomultiplier tubes.
Charge and/or scintillation light produced in this way can be collected to produce a detected signal.
Two photomultiplier tubes are used to detect the scintillation light produced by a particle interacting with the argon.
Optical fibers doped with a wavelength shifter collect scintillation light in physics experiments.
The energy of the particle may be then measured by the intensity of scintillation light produced by the various scintillator slices.
Transitions made by the free valence electrons of the molecules are responsible for the production of scintillation light in organic crystals.
A portion of the scintillation light propagates through the glass fiber, which acts as a waveguide.
