用于TOTEM实验的最终尺寸平面无边缘硅探测器
Final Size Planar Edgeless Silicon Detectors for the TOTEM Experiment
摘要：
TOTEM实验将探测从大型强子对撞机的相互作用点以微弧度角散射的领先质子。这将通过使用边缘死区最小化的探测器来实现。该合作在探测器边缘开发了一种创新结构，将传统的死宽度减少到100微米以下，仍然使用标准的平面制造技术。在这种新的发展中，表面的电流在几十微米内与敏感的体积电流解耦。本文阐述了其基本工作原理。使用这种方法已经生产出最终尺寸的探测器。研究了探测器的电流-电压特性和电流-温度特性，并在惯性流实验中进行了成功的测试。
英文摘要：
The TOTEM experiment will detect leading protons scattered in angles of microradians from the interaction point at the Large Hadron Collider. This will be achieved using detectors with a minimized dead area at the edge. The collaboration has developed an innovative structure at the detector edge reducing the conventional dead width to less than 100 microns, still using standard planar fabrication technology. In this new development, the current of the surface is decoupled from the sensitive volume current within a few tens of micrometers. The basic working principle is explained in this paper. Final size detectors have been produced using this approach. The current-voltage and current-temperature characteristics of the detectors were studied and the detectors were successfully tested in a coasting beam experiment.
