论文摘要
Belle II的硅顶点探测器是一种基于双面硅条带传感器的最先进的跟踪和顶点系统，该系统由2012年 - 2018年期间的大型国际合作设计和制造。自2019年以来，它一直在运行中提供高质量的数据，其中有少数有缺陷的通道（<1％），较大的击球效率（> 99％），良好的信噪比（对于所有传感器配置和轨道，超过10个）。加上对对齐方式的良好控制，这些都是实现良好跟踪重建和物理性能的基本因素。在本文的论文中，我们试图以向更广泛的社区提供信息的精神记录SVD挑战和成就的所有方面，并帮助开发高质量的检测器系统，这是进行物理学研究的基本工具。
The Silicon Vertex Detector of Belle II is a state-of-the-art tracking and vertexing system based on double-sided silicon strip sensors, designed and fabricated by a large international collaboration in the period 2012--2018. Since 2019 it has been in operation providing high quality data with a small number of defective channels (<1%), a large hit-finding efficiency (>99%), a good signal-to-noise ratio (well in excess of 10 for all sensor configurations and tracks). Together with the good control over the alignment, these are all essential factors to achieve good tracking reconstruction and physics performance. In this extended paper we try to document all the aspects of the SVD challenges and achievements, in the spirit of providing information to the broader community and help the development of high quality detector systems, which are fundamental tools to carry out physics research.
