我们进行了详细的研究的LHCb VELO Timepix 3望远镜的定时性能与180 GeV/c的混合强子束在欧洲核子研究中心SPS。为了提高单平面时间测量的分辨率，提出了一种双重方法，从而使整个轨道时间测量更加精确。第一步使用重构轨道的空间信息结合传感器中的测量信号电荷来校正不同效应的混合：电荷载流子漂移时间的变化;信号感应的变化，这是像素中的非均匀加权场的结果;最后，模拟前端中的时间游走。第二步校正Timepix 3中的系统时序偏移，范围为− 2至2 ns。应用该方法，跟踪时间分辨率从438（16）ps提高到276（4）ps。
We performed a detailed study of the timing performance of the LHCb VELO Timepix3 Telescope with a 180 GeV/c mixed hadron beam at the CERN SPS. A twofold method was developed to improve the resolution of single-plane time measurements, resulting in a more precise overall track time measurement. The first step uses spatial information of reconstructed tracks in combination with the measured signal charge in the sensor to correct for a mixture of different effects: variations in charge carrier drift time; variations in signal induction, which are the result of a non-uniform weighting field in the pixels; and lastly, timewalk in the analog front-end. The second step corrects for systematic timing offsets in Timepix3 that vary from− 2 to 2 ns. By applying this method, we improved the track time resolution from 438 (16) ps to 276 (4) ps.
