Title (EN) BORON COATED STRAWS FOR NEUTRON DETECTION WITH PIE-SHAPED CROSS-SECTION
(FR) PAILLES REVÊTUES DE BORE POUR LA DÉTECTION DE NEUTRONS, À SECTION TRANSVERSALE EN FORME DE TARTE
Abstract:
(EN) 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.
(FR) L'invention concerne un détecteur à paille recouverte de bore destiné à être utilisé dans un système de détection de neutrons, comprenant une paille revêtue de bore possédant au moins un septum revêtu de bore orienté radialement et s'étendant sur une distance prédéterminée vers le centre de la paille. De préférence, la paille comprend une pluralité de septums comprenant une surface rigide, revêtue des deux côtés d'une composition de bore. De préférence, les septums s'étendent sur la longueur du détecteur à paille d'une extrémité à l'autre de la paille. La zone revêtue sur les septums s'ajoutent à la zone revêtue sur les segments arqués, ce qui permet d'obtenir une amélioration sensible au niveau de la sensiblité du détecteur de neutrons.
