Abstract
This invention relates to an apparatus for detecting hydrogeneous material on a ship's deck comprising a neutron source located below the surface of the ship's deck and emitting fast/energy-rich neutrons, and a detector device that is located below the surface of the ship's deck and detecting thermal neutrons. The invention further relates to a corresponding method of detecting hydrogeneous material on a ship's deck. Hereby an apparatus and a method are provided for detecting occurrences of water on a ship's deck, wherein these occurrences appear in particular when travelling in rough weather conditions. The apparatus being located below the ship's deck, it is consequently not exposed to wear due to rough weather conditions.
Claims10
An apparatus (100) for detecting water on a ship's deck (110), where that the apparatus comprises:
- a neutron source (103) located below the surface of the ship's deck (110), and emitting fast/energy-rich neutrons (111);
- and
- a detector device (102, 102a, 102b) located below the surface of the ship's deck (110) and detecting thermal neutrons,
- characterized in that the apparatus further comprises:
- a light-emitting unit (102b) that emits light upon a nuclear event/reaction with a thermal neutron;
- a light-recording unit (102a) that emits an electrical pulse or an electrical signal (106) upon registration of a flash of light;
- and
- a moderator (104′, 104″) that is located below the surface of the ship's deck (110) and brakes and reflects neutrons upon collision;
- wherein the moderator (104′;
- 104″) is a light-conductive unit provided between the light-emitting unit (102b) and the light-recording unit (102a).
A method of detecting water on a ship's deck (110), comprising the following steps:
- emission of energy-rich neutrons (111) from a neutron source (103) that is located below the surface of the ship's deck (110);
- and
- detection of thermal neutrons by means of a detector device (102;
- 102a;
- 102b) that is located below the surface of the ship's deck (110), characterized in that the method further comprises the following:
- emission of light from a light-emitting unit (102b) upon a nuclear event/reaction with a thermal neutron;
- emission of an electric pulse or an electrical, signal (106) by a light-recording unit (102a) upon registration of a flash of light;
- conduction of light from said light-emitting unit (102b) to the light-recording unit (102a) by a light-conductive unit arranged between the light-emitting unit (102b) and the light-recording unit (102a), wherein the moderator (104′;
- 104″) is the light-conductive unit;
- and
- braking and reflecting neutrons upon collision by means of a moderator (104′;
- 104″) that is located below the surface of the ship's deck (110).
