<p><P>PROBLEM TO BE SOLVED: To provide an apparatus and method, which manufacture a microchannel plate having an asymmetric packing pattern for a higher open area ratio (OAR). <P>SOLUTION: A boule for making a microchannel plate includes (a) at least two sets of rows of fibers, each set arranged to form a hexagonally shaped boundary of fibers, and (b) an additional row of fibers disposed between two sets of hexagonally shaped boundary fibers. The additional row of fibers includes a horizontally oriented row of fibers, which is packed on the top of a horizontally oriented boundary fibers. A fiber of the horizontally oriented row of boundary fibers is packed adjacent to two consecutive fibers of the additional row of fibers, forming a triangular shape of fibers. The triangular shape of fibers form a maximum open area ratio (OAR) of at least 90%. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
