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.

Abstract: A stabilizing upper tray for stabilizing cartridges during automated filling operations includes fill ports matching cartridge support locations in a lower support tray. Each fill port includes a bore, a circular recess to engage the upper rim of a cartridge, and an inwardly tapered needle-engaging surface adapted to be engaged by a fluid injection needle; a counterbore extends between the bore and the circular recess. As the upper tray is lowered over the cartridges, the enlarged recess of each fill port engages a corresponding cartridge and guides it into a vertical orientation within the counterbore. During filling operations, a mis-aligned fluid injection needle engages the inwardly tapered needle-engaging surface of the stabilizing upper tray and is guided through the fill port toward the cartridge. A method is also disclosed to form such a stabilizing upper tray through conversion of a conventional lower support tray.
