Scintillator array for radiation detection
| DWPI Title: Making radiation detector involves cooling amorphous scintillator material within interior cavity to form scintillator, and coupling the mold to photodetector such that photodetector receives light that is emitted by the scintillator responsive to incidence of radiation at the scintillator |
| Abstract: A radiation detector includes a photodetector and a scintillator coupled thereto. The scintillator is formed of a scintillator material comprising an organic glass scintillator (OGS) material and at least one of a polymer additive or a plasticizer additive. The scintillator emits light when radiation is received at the scintillator, and the light is received by the photodetector. The radiation detector can further include a frame that has an interior cavity that holds the scintillator in position with respect to the photodetector, such that the light emitted by the scintillator is transmitted to the photodetector. The scintillator can be formed by casting amorphous scintillator material in the interior cavity of the frame. The frame can then be coupled to the photodetector to form the radiation detector. |
| Use: Method for making a radiation detector. |
| Advantage: The method employs non-subtractive methods such as mold casting or extrusion to form scintillator elements, which improves the manufacturing yield, reliability, and performance of the radiation detectors relative to conventional radiation detectors that rely on stilbene or plastic scintillators. |
| Novelty: The method involves providing a photodetector; providing a mold, having an interior cavity; flowing an amorphous scintillator material into the interior cavity of the mold; cooling the amorphous scintillator material within the interior cavity to form a scintillator; and coupling the mold to the photodetector such that the photodetector receives light that is emitted by the scintillator responsive to incidence of radiation at the scintillator. The amorphous scintillator material comprises an organic glass scintillator (OGS) material and at least one of a plasticizer additive or a polymer. |
