Abstract: | The various technologies presented herein relate to incorporating a
wavelength-shifting material in a scintillator to facilitate absorption
of a first electromagnetic particle (e.g., a first photon) having a first
wavelength and subsequent generation and emission of a second
electromagnetic particle (e.g., a second photon) having a second
wavelength. The second electromagnetic particle can be emitted
isotropically, with a high probability that the direction of emission of
the second electromagnetic particle is disparate to the direction of
travel of the first electromagnetic particle (and according angle of
incidence). Isotropic emission of the second electromagnetic particle
enables the second electromagnetic particle to be retained in the
scintillator owing to internal reflection. Accordingly, longer length
scintillators can be constructed, and accordingly, the scintillator array
has a greater area (and volume) over which to detect electromagnetic
particles (e.g., antineutrinos) being emitted from a nuclear reaction. |
