在本文中，一个基于计算机的分析进行研究的布局解决方案，旨在提高硅微带探测器的击穿电压。对于最佳性能，它是至关重要的，以实现最大的击穿电压硅探测器工作在非常高的偏置，由于下一代实验，如大型强子对撞机的极端恶劣的辐射环境。硅微带探测器的性能可以通过在有源探测器区域周围实现浮动场限制环来改善。已经进行了模拟研究，以评估作为保护环间距（GS）的函数的击穿电压的分布。本工作的目的是找到一个标准，以优化GS的多个环结构，包括各种物理和几何参数作为设计优化的援助。利用该准则，得到了多环结构中保护环的最佳间距。该判据具有很强的鲁棒性，对保护环数目、结深和辐射损伤不敏感。七环设计的仿真结果与实验测量结果吻合良好。
In this paper, a computer-based analysis is performed to study layout solutions aimed at increasing the breakdown voltage in Si-microstrip detectors. For optimum performance it is crucial to achieve maximum breakdown voltage for Si detectors operating at very high bias due to the extremely hostile radiation environment of next generation experiments such as LHC. The performance of Si-microstrip detectors can be improved by implementing floating field-limiting rings around the active detector area. A simulation study has been carried out to evaluate the distribution of breakdown voltage as a function of guard-ring spacing (GS). The purpose of this work is to find a criterion to optimize GS for multiple ring structures incorporating various physical and geometrical parameters as an aid to design optimization. Using this criterion the optimum spacing of guard rings for multiple ring structures was obtained. The proposed criterion is very robust and is insensitive to the number of guard rings, junction depth and radiation damage. The simulation results for the seven-ring design agree well with experimental measurements.
