Omni-directional solid-state thermal neutron detector

A directional neutron detecting apparatus comprising:

• a first neutron detector, said first neutron detector including
• a planar sheet of neutron-reactive material;
• a first ohmic electrode operably coupled directly to one side of said planar sheet of neutron-reactive material;
• a second ohmic electrode operably coupled directly to a second side of said planar sheet of neutron-reactive material;
• a voltage source operably coupled to said first and second ohmic electrodes;
• and
• an electrical current detector operably coupled in series between said first ohmic electrode and said voltage source, and
• a second neutron detector, said second neutron detector including
• a planar sheet of neutron-reactive material;
• a first ohmic electrode operably coupled directly to one side of said planar sheet of neutron-reactive material;
• a second ohmic electrode operably coupled directly to a second side of said planar sheet of neutron-reactive material;
• a voltage source operably coupled to said first and second ohmic electrodes;
• and
• an electrical current detector operably coupled in series between said first ohmic electrode and said voltage source,
• wherein said first and second neutron detectors are arranged so that their planar sheets of neutron-reactive material are substantially parallel, opposing and are spaced from each other and wherein said planar sheets of neutron-reactive material each have a thickness and a planar face, said planar face having a linear dimension wherein said planar sheet is categorized by an aspect ratio, said aspect ratio being a ratio of said linear dimension to said thickness of said neutron-reactive material sheet, and further wherein said aspect ratio is at least 10.
