Abstract

A method and apparatus to manufacture a coherent bundle of scintillating fibers is disclosed. A method includes providing a collimated bundle having a glass preform with capillaries therethrough known in the industry as a glass capillary array, and infusing the glass capillary array with a scintillating polymer or a polymer matrix containing scintillating nanoparticles.

First claim

What is claimed is:

1. A method comprising:
providing a collimated bundle having a glass preform with a plurality of capillaries therethrough known in the industry as a glass capillary array;
infusing the glass capillary array with a scintillating polymer;
placing the collimated bundle in a pressure vessel;
applying pressure to the scintillating polymer;
driving it into the capillaries; and
applying a back pressure to the collimated bundle, the back pressure reducing the risk of failure of the collimated bundle.

2. The method of claim 1 wherein the back pressure is applied by a high pressure gas.

3. A method comprising:
providing a micro-capillary plate having a plurality of capillary openings;
filling the plurality of capillary openings with a low index polymer;
blowing out the plurality of capillary openings under pressure to leave a layer of low index wall coating; and
curing the low index wall coating with ultraviolet light.
