High efficiency proportional neutron detector with solid liner internal structures

A neutron detector comprising:

• at least one panel including a plurality of channels therethrough and spaced from each other along a first direction, wherein each of said plurality of channels is laterally surrounded by a coating layer of a neutron-absorbing material and extends along said first direction;
• at least one cathode plate located at least on one side of each of said at least one panel;
• and
• a first array of first substantially parallel wire anodes located on another side of each of said at least one panel and extending along a second direction that is perpendicular to said first direction and spaced from said each of said at least one panel along said first direction by a first distance;
• and
• a second array of second substantially parallel wire anodes located on said another side of each of said at least one panel, spaced from said first array and extending along a third direction that is perpendicular to said first direction and said second direction and spaced from said each of said at least one panel along said first direction and spaced from said each of said at least one panel along said first direction by a second distance that is different from said first distance.
