Abstract

Recen% developed near W-photosensors are currently adopted in those applications where high sensitivity and good imaging capabilities are required, especially in fields such as astroparticle physics and medical imaging. An example of such applications is the camera of the Schwarzschild Couder Medium Size Telescope prototype (pSCT) which is in construction within the Cherenkov Telescope Array experiment. The camera consists of 177 photo-detection modules grouped into sectors of 25 modules, each based on matrixes of 64 6mm × 6mm pixels of SiUcon PhotomultipUers (SiPMs). Sensors produced by the Fondazione Bruno Kessler (FBK) in Italy are currently under investigation. Here we present a complete characterization of these highly sensitive near UV sensors, the assembly procedure and metrology results on several focal plane elements.

用于医学成像和天体物理应用的16通道光探测传感器矩阵的开发

最近开发的近w光传感器目前被用于需要高灵敏度和良好成像能力的应用，特别是在天体粒子物理和医学成像等领域。这种应用的一个例子是在切伦科夫望远镜阵列实验中建造的史瓦西德Couder中型望远镜原型(pSCT)的相机。该相机由177个光探测模块组成，每个模块分为25个扇区，每个模块基于64 6mm × 6mm SiUcon PhotomultipUers (sipm)像素的矩阵。意大利布鲁诺凯斯勒基金会(FBK)生产的传感器目前正在接受调查。本文介绍了这些高灵敏度近紫外传感器的完整特性、组装过程和几个焦平面元件的测量结果。
