论文摘要
我们使用Brookhaven National Laboratory生产的Fermilab测试梁设施和传感器，使用Fermilab测试梁设施和传感器提出了第一个光束测试结果。对于需要经济通道计数的大区块精度4D跟踪覆盖范围的应用，设想了这种类型的传感器，包括电子离子对撞机（EIC）和空间粒子实验的定时层。提出了传感器设计的调查，目的是优化电极几何形状，以进行空间分辨率和时序性能。讨论了一些设计考虑因素，以维持越来越大的电极维持理想的信号特性。提出了用几个原型获得的分辨率，从1厘米长的条和500微米的螺距中达到了18微米和32 ps分辨率。仅通过轻微的修改，这些传感器将是EIC 4D时层的理想候选者。
We present the first beam test results with centimeter-scale AC-LGAD strip sensors, using the Fermilab Test Beam Facility and sensors manufactured by the Brookhaven National Laboratory. Sensors of this type are envisioned for applications that require large-area precision 4D tracking coverage with economical channel counts, including timing layers for the Electron Ion Collider (EIC), and space-based particle experiments. A survey of sensor designs is presented, with the aim of optimizing the electrode geometry for spatial resolution and timing performance. Several design considerations are discussed towards maintaining desirable signal characteristics with increasingly larger electrodes. The resolutions obtained with several prototypes are presented, reaching simultaneous 18 micron and 32 ps resolutions from strips of 1 cm length and 500 micron pitch. With only slight modifications, these sensors would be ideal candidates for a 4D timing layer at the EIC.
