Abstract
Scintillation crystals are the most widely used detector components for radiation detection, especially for X-ray detection, in the fields of nuclear and particle physics and for space and medical applications. We measured the X-ray energy by using a detector that consisted of a Ce-doped silicate scintillation crystal and a photosensor. The silicate scintillation crystal is either a Yttrium Silicon Oxide (YSO) crystal or a Lutetium Yttrium Silicon Oxide (LYSO) crystal, and the photosensor is a silicon photomultiplier with its photon-detection efficiency optimized for the emission spectrum of the scintillation crystals. We used the detector to observe the full-energy distribution of X-rays in the range of 11.9 and 26.3 keV with an average energy of 17.1 keV, as well as the full-energy distribution of X-rays with an energy of 59.5 keV from an
섬광결정체는 핵, 입자물리, 우주관측 및 의료진단 분야에서 방사선 검출 특히 X-선의 검출에 널리 사용되는 검출기의 하나이다. 본 연구에서는 세륨이 도핑된 실리케이트 섬광결정체와 광 센서로 구성된 검출기를 사용하여 X-선의 에너지를 측정하였다. 실리케이트 섬광결정체로는 Yttrium Silicon Oxide (YSO) 혹은 Lutetium Yttrium Silicon Oxide (LYSO)를 사용하였으며, 광 센서로는 광 검출효율이 이들 섬광결정체의 방출 스펙트럼에 최적화된 실리콘 광전자증배 소자를 사용하였다. 이 검출기를 사용하여
