ABSTRACT:
The present invention discloses a method for manufacturing a photon detector and image generator. First, a screen operable to display a visual image based on a received signal is provided. The screen is then scrubbed. Next, an unfilmed microchannel plate having an input face and an output face is provided. The microchannel plate is baked in a vacuum chamber and a tube assembly is formed by attaching the microchannel plate to the screen. The tube assembly is scrubbed using an electron gun. Next, a photocathode, having an input side and an output side, is attached to the assembly such that the output side of the photocathode faces the input face of the microchannel plate in order to form a final tube, wherein the tube has a lifetime greater than 7,500 hours.
