标题： Amplitude Walk in Fast Timing: The Role of Dual Thresholds

摘要： 为HL-LHC运行做准备，正在建造一些新的探测器系统，其物理对象的时间精度为$\leq50$皮秒。 这些时间戳将减少堆叠引起的背景水平，因为每束流的相互作用数量将达到100-200的数量级。 在本报告中我们注意到，这种高堆叠水平将需要一种新的方法来校准这些大型时间阵列（通常具有几个$\times10^5$通道），因为在常规数据获取中很难获得单一的t$_{0}$参考。 我们证明，通过增加第二个阈值时间来增强通常的时间ASIC数据（即阈值时间和幅度或过阈值时间），可以大大简化幅度行走的分析。 由于阈值处的斜率直接与幅度行走相关，第一天的行走校准通常可以有解析解。 显示英文摘要

摘要： In preparation for HL-LHC operation, a number of new detector systems are being constructed with timing precision on physics objects of $\leq50$ picoseconds. These time stamps will reduce the level of pileup induced backgrounds as the number of interactions per crossing will reach of order 100-200. In this report we note that this high pileup level will necessitate a new approach to calibration of these large timing arrays (typically with several $\times10^5$ channels) since a single t$_{0}$ reference is hard to come by in regular data taking. We demonstrate that enhancing the usual pair of timing ASIC data (ie threshold time and amplitude or time-over-threshold) with a 2nd threshold time greatly simplifies the analysis of amplitude walk. Since slope at threshold is directly relevant for amplitude walk, day-1 walk calibration can often have an analytical solution.
