Abstract:
A method and apparatus to manufacture a coherent bundle of scintillating fibers is disclosed. In the method and apparatus, a polymer matrix of a transparent polymer and nanoparticle scintillators is placed on top of a collimated bundle having a plurality of capillaries and pressed in a pressure vessel until the polymer matrix is forced into the capillaries. Pressure is applied via an anvil on top of the polymer matrix. To prevent fracturing of the collimated bundle during pressing, back pressure is supplied to the pressure vessel via a valve, which controls a supply of high pressure gas. Alternatively, the back pressure may also be supplied by a press (and or pressure) and support to the collimated bundle is provided by a high melting point thermoplastic. Heat may be applied to the polymer matrix via the anvil to speed the pressing operation due to the viscosity of the polymer.

Abstract:
A molded panel is provided, which includes a body and a plurality of supporting members. The body includes a generally planar top surface and a bottom surface. The supporting members extend from the bottom surface of the body to define a support structure. The support structure includes a top surface adjacent to the bottom surface of the body, a generally planar bottom surface and at least one edge extending therebetween. The support structure also includes at least one channel extending along a central x-axis of the support structure, and at least one additional channel intersecting the at least one central channel and extending along a y-axis of the support. The y-axis is generally perpendicular to the x-axis. A connection system for the molded panel, systems including the molded panel, and methods related to the molded panel are also described.
