论文摘要
本论文报告了在CGEM-IT项目的背景下开发的圆柱形宝石检测器生命周期的各个阶段。这代表了意大利升级BESIII Inner Tracker的意大利提议，该升级者由于高光度而遭受了老化现象的困扰。详细描述了在Frascati国家实验室的检测器及其调试的早期阶段的建设。在最后两章中，将介绍使用CGEM检测器收集的数据，并在BEPC-II相互作用点附近具有完整的读取链收集的数据，从探测器电子设备的质量保证测试开始。实现测量值以利用BEPC-II存储环的不同操作阶段，并旨在估算由于周围环境而引起的噪声水平变化。
This thesis reports the various phases of the life cycle of a cylindrical GEM detector, developed within the context of the CGEM-IT project. This represents the Italian proposal for the upgrade of the BESIII inner tracker, which has been suffering from aging phenomena due to the high luminosity. The construction of the detector at Frascati National Laboratories and the early phases of its commissioning at IHEP are described in detail. In the last two chapters, noise studies on data collected using a CGEM detector with a full readout chain near the BEPC-II interaction point will be presented, starting from the quality assurance tests of the on-detector electronics. The measurements are realized exploiting the different operative phases of the BEPC-II storage ring and aim to provide an estimate of the noise level variation due to the surrounding environment.
