A neutron detector includes a shell bounding an interior volume. A portion of the neutron detector serves as a cathode. The detector includes a central structure located within the interior volume and serving as an anode. The detector includes a boron coating on the interior of the wall wherein at least some of the boron coating is heat diffused into the wall from a boron-containing powder to form the boron coating which is sensitive to neutrons. The detector includes an electrical connector operatively connected to the central structure for transmission of a signal collected by the central structure. An associated method of heat diffusing the boron includes subjecting boron-containing powder to an elevated temperature so that a quantity of the boron-containing powder heat diffuses. |
