Filed:

Jul 20, 2010

Appl. No.:

12/839656

Inventors:

Haochuan Jiang - Brookfield WI, US
Kevin Alan David - Waterford WI, US

International Classification:

B29C 43/02

US Classification:

264319, 425197

Abstract:

A manufacturing line for fabricating a scintillator that includes a vat configured to receive a mixture of scintillator components. The mixture includes a dissolved acid solution comprising a rare earth element, a gallium compound, an aluminum compound, and a cerium salt. The vat is further configured to react a base solution with the mixture to form a precipitate. The manufacturing line further includes a separator configured to separate the precipitate from a remaining portion of the mixture, and a compaction device configured to compact the precipitate to form a green ceramic wafer.

US Classification:

378 19, 250361 R, 29428, 250367

Abstract:

Systems and method for filtering emissions from scintillators are provided. One system includes a scintillator having a scintillator material portion formed from a base scintillator material. The scintillator also includes a photodetector and a filter portion, The filter portion includes a material blocking near-infrared (IR) emissions. The filter portion is disposed on a surface of one of the scintillator material portion or the photodetector, and wherein the scintillator material portion, the photodetector, and the filter portion are coupled together. The filter portion blocks the near-IR emissions from impinging on the photodetector.
