(EN) GAMMA-RAY SPECTROMETER CALIBRATION SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS D'ÉTALONNAGE DE SPECTROMÈTRE À RAYONS GAMMA
Abstract
(EN)
A gamma-ray spectrometer calibration system comprises a light guide, a photomultiplier tube, a laser, and analysis electronics. The light guide is optically coupled to the scintillation crystal, the laser and the photomultiplier tube, such that the laser can provide reference signals to the photomultiplier tube. In some embodiments, one or more temperature sensors are provided, such that the analysis electronics determine initial settings and adjust the initial settings based on the temperatures measured by the temperature sensors. Additional apparatus, methods, and systems are disclosed.

L'invention concerne un système d'étalonnage de spectromètre à rayons gamma qui comprend un guide de lumière, un tube photomultiplicateur, un laser, et une électronique d'analyse. Le guide de lumière est optiquement couplé au cristal à scintillation, au laser et au tube photomultiplicateur, de telle sorte que le laser puisse fournir des signaux de référence au tube photomultiplicateur. Dans certains modes de réalisation, un ou plusieurs capteurs de température sont prévus, de telle sorte que l'électronique d'analyse détermine des paramétrages initiaux et ajuste les paramétrages initiaux sur la base des températures mesurées par les capteurs de température. La présente invention concerne également un appareil, des procédés et des systèmes supplémentaires.
