Title (EN) PHOTOMULTIPLER-BASED NEUTRON DETECTOR
(FR) DÉTECTEUR DE NEUTRONS BASÉ SUR UN TUBE PHOTOMULTIPLICATEUR
Abstract: front page image
(EN)A neutron detector is provided which may include a neutron converting layer, and a scintillator layer adjacent the neutron converting layer. The neutron detector may further include a photomultiplier adjacent the scintillator layer. By way of example, the neutron detector may be used in a well logging apparatus to determine a neutron flux incident upon the neutron converting layer, and thereby determine the neutron porosity of a geological formation around a wellbore.
(FR)L'invention concerne un détecteur de neutrons, qui peut comprendre une couche de conversion de neutrons et une couche de scintillateur adjacente à la couche de conversion de neutrons. Le détecteur de neutrons peut comprendre en outre un tube photomultiplicateur adjacent à la couche de scintillateur. A titre d'exemple, le détecteur de neutrons peut être utilisé dans un appareil de diagraphie afin de déterminer un flux de neutrons incident sur la couche de conversion de neutrons et déterminer ainsi la porosité aux neutrons d'une formation géologique autour d'un puits de forage.
