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.
