Abstract
A radiation detection apparatus can include a radiation sensor having a corresponding radiation sensing region, and a photosensor that is optically couple to the radiation sensor. The radiation sensing region can include optical fibers. In an embodiment, some or all of the optical fibers can be coated. The coating can include a phosphorescent material. In an embodiment, the optical fibers can be arranged in a manner such that optical substrates have substantially no bends.
Claims13
A radiation sensor having a radiation sensing region, wherein the radiation sensor comprises:
- optical fibers comprising optical substrates including a particular optical substrate,
- wherein:
- a coating is adjacent to the particular optical substrate;
- the coating includes a phosphorescent material that includes a neutron sensitive material,
- wherein the phosphorescent material includes a first material and a second material;
- the first material includes 6Li or 10B;
- and
- the second material includes a ZnS, a CdWO4, a Y2SiO5, a ZnO, a ZnCdS, or any combination thereof;
- and
- from a cross-sectional view, the coating substantially completely surrounds a perimeter of the particular optical substrate,
- wherein the radiation sensor does not include a dedicated neutron moderator surrounding radiation sensor.
A radiation sensor having a radiation sensing region, wherein the radiation sensor comprises:
- optical fibers comprising optical substrates, wherein:
- coatings are adjacent to at least some individual optical substrates;
- each of the coatings includes a phosphorescent material and is an exterior surface of the optical fiber;
- wherein the phosphorescent material includes a first material and a second material;
- the first material includes 6Li or 10B;
- and
- the second material includes a ZnS, a CdWO4, a Y2SiO5 a ZnO, a ZnCdS or any combination thereof;
- and
- within the radiation sensing region of the radiation sensor, the optical fibers are arranged such that a majority of the optical fibers contact at least three other optical fibers.
