论文摘要
该事件平面检测器(EPD)安装在位于布鲁克黑文国家实验室的相对论重型离子对撞机上的螺线管跟踪器中,是一种基于塑料闪烁的设备,可测量相对主义重型离子碰撞的正向区域的反应中心性和事件平面。我们使用硅光电层层(SIPM)阵列来检测闪烁体通过纤维连接产生的光子。来自SIPM阵列的信号通过前端电子(费用)板放大,并发送到模数转换器(ADC)板,以通过接收器(RX)板进行进一步处理。完整的EPD系统由24个超级领域(SSS)组成;每个SS都配备了两个SIPM板,两个费用板和两个RX板,它们对应于744个读取频道。所有这些董事会都是在中国科学技术大学生产的,采用了专门的质量保证(QA)程序,用于在部署前确定任何问题。本文介绍了质量检查方法和相关测试系统的详细信息。 QA测试结果与讨论一起介绍。
The event plane detector (EPD), installed in the Solenoid Tracker at the Relativistic Heavy-Ion Collider located at the Brookhaven National Laboratory is a plastic scintillator-based device that measures the reaction centrality and event plane in the forward region of the relativistic heavy-ion collisions. We used silicon photomultiplier (SiPM) arrays to detect the photons produced in the scintillator via the fiber connection. Signals from the SiPM arrays were amplified by the front-end electronic (FEE) board, and sent to the analog-to-digital converter (ADC) boards for further processing via the receiver(RX) board. The full EPD system consisted of 24 super-sectors (SSs); each SS was equipped with two SiPM boards, two FEE boards and two RX boards, and they corresponded to 744 readout channels. All these boards were mass produced at the University of Science and Technology of China, with a dedicated quality assurance (QA) procedures applied to identify any problems before deployment. This article describes the details of the QA method and the related test system. The QA test results are presented along with the discussions.
