Abstract
(EN)
The present invention relates to a structure for mounting a photomultiplier tube (PMT) to a scintillator, which is provided with a fixing means for fixing, to a scintillator panel (30) for generating visible light by means of radiation collision, a PMT (10)for detecting the visible light, wherein the fixing means: comprises a clamp (20) on a front surface part (21) of which a holder (25) for keeping the PMT (10) in contact with the scintillator panel is provided; and fixes the clamp (20)with respect to the top surface and the bottom surface of the scintillator panel (30). Accordingly, the present invention allows the PMT to be easily mounted without damaging the scintillator panel and consequently enables more accurate radiation detection without any light loss which used to occur when mounting a PMT due to a crack in a scintillator panel and a screw inserted into the crack.

La présente invention concerne une structure de montage d'un tube photomultiplicateur (PMT) sur un scintillateur, qui est pourvu d'un moyen de fixation pour fixer, à un panneau de scintillateur (30) pour générer une lumière visible au moyen d'une collision de rayonnement, un PMT (10) pour détecter la lumière visible, dans laquelle le moyen de fixation : comprend une pince (20) sur une partie de surface avant (21) dont un support (25) pour maintenir le PMT (10) en contact avec le panneau de scintillateur est disposé; et fixe la pince (20) par rapport à la surface supérieure et à la surface inférieure du panneau de scintillateur (30). En conséquence, la présente invention permet de monter aisément le PMT sans endommager le panneau de scintillateur et, par conséquent, permet une détection de rayonnement plus précise sans perte de lumière qui survient couramment lors du montage d'un PMT en raison d'une fissure dans un panneau de scintillateur et d'une vis insérée dans la fissure.

본 발명은 방사선의 충돌에 의해 가시광을 발생하는 섬광체 패널(30)에 상기 가시광을 검출하기 위한 PMT(10)를 고정하기 위한 고정수단을 구비한 섬광체에의 광증배관(PMT) 장착구조에 관한 것으로, 상기 고정수단은 전면부(21)에 PMT(10)을 섬광체 패널에 접촉되게 유지하는 홀더(25)를 구비한 클램프(20)로 구성되고, 상기 클램프(20)를 섬광체 패널(30)의 상면과 저면에 대해 고정하는 고정수단을 포함하는 것을 특징으로 하여 구성됨으로써, 섬광체 패널을 손상시키지 않고 PMT를 간편하게 장착할 수 있고, 이에 따라 종래 PMT 장착시 섬광체 패널의 크랙과 그 속에 삽입되는 스크류로 인한 광손실이 발생되지 않아 방사선 측정을 보다 정확히 할 수 있는 효과가 있다.
