摘要： An apparatus and a process is disclosed for applying a boron coating to a thin foil. Preferably, the process is a continuous, in-line process for applying a coating to a thin foil comprising wrapping the foil around a rotating and translating mandrel, cleaning the foil with glow discharge in an etching chamber as the mandrel with the foil moves through the chamber, sputtering the foil with boron carbide in a sputtering chamber as the mandrel moves through the sputtering chamber, and unwinding the foil off the mandrel after it has been coated. The apparatus for applying a coating to a thin foil comprises an elongated mandrel. Foil preferably passes from a reel to the mandrel by passing through a seal near the initial portion of an etching chamber. The mandrel has a translation drive system for moving the mandrel forward and a rotational drive system for rotating mandrel as it moves forward. The etching chamber utilizes glow discharge on a surface of the foil as the mandrel moves through said etching chamber. A sputtering chamber, downstream of the etching chamber, applies a thin layer comprising boron onto the surface of the foil as said mandrel moves through said sputtering chamber. Preferably, the coated foil passes from the mandrel to a second reel by passing through a seal near the terminal portion of the sputtering chamber.

摘要： A neutron detector includes an exterior shell (20) bounding an interior volume. The neutron detector includes at least a wall portion (30) serving as a cathode. In one example the wall portion has microfeatures. The neutron detector includes a central structure (54) located within the interior volume and serving as an anode. The neutron detector includes a boron coating (60) on the wall portion (30). In on example, the boron coating is applied by an electrostatic spray process. In one example, the boron coating conforms to the microfeatures on the wall portion. In one example, the wall portion (30) has a thickness of between 2 to 5 microns. The neutron detector includes an electrical connector (61) operatively connected to the central structure (54) for transmission of a signal collected by the central structure. An associated method provides for depositing the boron coating.

摘要： The present invention discloses a boron-coated neutron detector, comprising a cathode tube with a plurality of passages formed therein along its longitudinal direction, the inner wall of each passage being coated with boron material; an electrode wire serving as an anode and arranged longitudinally in each of the passages, the electrode wire adapted to be applied with high voltage; and an insulating end plate to which each end of the cathode tube is fixed, the electrode wire being fixed to the cathode tube via the insulating end plate. Preferably, the cathode tube is formed by jointing a plurality of boron-coated substrates. By arranging in the cathode tube a plurality of passages coated with boron material on their inner walls, the boron-coated neutron detector increases the detection efficiency of the neutron detector, which may reach or even exceed the detection efficiency of the 3 He neutron detector of the same size, and the cost thereof is much cheaper than the 3 He neutron detector.
