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.
Claims20
An improved boron-coated straw detector system comprising a boron-coated straw having a diameter and at least one septum extending radially inward from inner surface of the straw, each septum having a boron-coating on two sides.
An improved boron-coated straw detector system comprising a boron-coated straw having a diameter and at least one septum extending radially inward from inner surface of the straw, each septum having a boron-coating on two sides, wherein each septum has a length of about 0.31 times the straw diameter or less.
An improved boron-coated straw detector system comprising a boron-coated straw having a diameter and at least one septum extending radially inward from inner surface of the straw, each septum having a boron-coating on two sides, wherein the straw comprises a plurality of septa and wherein the ratio of the length of each septum to the length of an arch between each septum is less than or equal to the number of septa in the straw divided by 2π.
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 inner surface of the straw, and each septum having a boron-coating on both sides.
A wearable neutron detection system comprising
- a plurality of detector modules, each detection module 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 inner surface of the straw, and each septum having a boron-coating on both sides;
- a controller that collecting and combining signals from the detector modules;
- cables connecting detector modules with the controller for transmitting data;
- a vest, the vest holding the plurality of detector modules, the connecting cables, and the controller.
