Abstract
A boron coated straw detector for use in a neutron detection system is disclosed comprising a boron coated straw having at least one boron-coated septum radially oriented and extending a pre-determined distance towards the center of the straw. Preferably, the straw comprises a plurality of septa comprising a rigid surface, coated on both sides with a boron composition. Preferably, the septa run the length of the straw detector from one end of the straw to the other. The area coated on the septa adds to the area coated on the arc segments offering a significant benefit in sensitivity of the neutron detector.
Claims21
An improved boron-coated straw detector system comprising a boron-coated straw having a diameter and a plurality of septa extending radially inward from an inner surface of the straw, each septum having a boron-coating on two sides and a length of about 0.25 times the straw diameter or less, wherein each septum is within about 5% difference in length.
A neutron detection system comprising a plurality of boron-coated straws formed into a panel, each boron-coated straw in the panel having a plurality of septa extending radially inward from an inner surface of the straw, and each septum having a boron-coating on both sides, wherein each septum within a straw is within about 5% difference in length.
A neutron detection system comprising a plurality of boron-coated straws formed into a panel, each boron-coated straw in the panel having a plurality of septa extending radially inward from an inner surface of the straw, and each septum having a boron-coating on both sides, wherein the panel is about 5.0 cm by 10 cm in size.
A neutron detection system comprising a plurality of boron-coated straws formed into a panel, each boron-coated straw in the panel having a plurality of septa extending radially inward from an inner surface of the straw and each septum having a boron-coating on both sides, wherein the panel weighs about 0.1 pounds or less.
