使用光纤传感器的跟踪器和顶点系统的结构和环境监测

Structural and environmental monitoring of tracker and vertex systems using Fiber Optic Sensors

David Moya, Iván Vila

摘要:

光纤传感器(FOS)是土木工程、航空航天和能源等多个领域的环境和变形监测的成熟技术。它们对电磁和磁场以及核环境的免疫力、其小尺寸、多路复用能力以及嵌入的可能性使它们成为对撞机粒子物理实验的结构和环境监测的有吸引力的技术。在所有可能的光纤传感器中,FBG(光纤布拉格光栅)似乎是HEP应用的最佳解决方案。第一步是表征FBG传感器,以便在高能物理环境中使用。在过去的两年中,我们已经检查了光纤光栅传感器的抗辐射性。在CNA(Centro Nacional de Acceleradores)进行了两次质子辐照活动。在不久的将来,这些传感器计划用于探测器(最近的一个Belle II)。对Belle II PXD-SVD的集成问题以及探测器内部的环境和变形监测进行了一些工作。

英文摘要:

Fibre optic sensors (FOS) are an established technique for environmental and deformation monitoring in several areas like civil engineering, aerospace, and energy. Their immunity to electromagnetic and magnetic fields and nuclear environments, its small size, multiplexing capability and the possibility to be embedded make them an attractive technology for the structural and environmental monitoring of collider particle physics experiments. Between all the possible Fibre Optic sensors FBGs (Fiber Bragg Grating) seems to be the best solution for HEP applications. The first step was to characterize FBG sensors for it use in High Energy Physics environment. During last two years we have checked the resistance of the Fibre Bragg Grating sensors to radiation. Two irradiation campaigns with protons have been done at CNA (Centro Nacional de Aceleradores). In the near future these sensors are being planned to be used in detectors (the closest one Belle II.). Several work on integration issues in Belle II PXD-SVD, and checking for environmental and deformation monitoring in the detectors inner part has been done.
