探测器系统的设计与TimePix4 ASIC的四个硅传感器组成,并将其数据采集系统,操作基础架构和专用软件进行描述。该系统的空间和时间性能通过CERN SPS的180 GEV/C混合强子束评估,并详细报告。使用四个检测器平面的时空测量进行重建粒子轨道。空间命中分辨率评估为$(15.5 \ pm 0.5)$ $ $ $ m和$(4.5 \ pm0.3)$ $ $ $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m $ m厚的传感器。探测器的时间戳还以良好的精度测量,得出$(452 \ pm10)$ ps,$(420 \ pm10)$ PS,$(639 \ pm10)$ PS,$(631 \ pm10),$(631 \ pm10)$ PS分别分别用于两100 $ $ m $ m $ m $ m $ m $ m $ m $ m $ m $ mm $ $。这些测量值合并到$(340 \ pm 5)$ ps的轨道时间分辨率。
The design of a detector system comprised of four silicon sensors bump-bonded to Timepix4 ASICs is described together with its data acquisition system, operational infrastructure, and dedicated software. The spatial and temporal performance of the system are assessed with a 180 GeV/c mixed hadron beam at the CERN SPS and reported in detail. Particle tracks are reconstructed using time-space measurements from the four detector planes. The spatial hit resolution is assessed to be $(15.5\pm 0.5)$ $μ$m and $(4.5\pm0.3)$ $μ$m for 100 and 300 $μ$m thick sensors, respectively. The timestamps from the detectors are also measured with fine precision, yielding time resolutions of $(452\pm10)$ ps, $(420\pm10)$ ps, $(639\pm10)$ ps, $(631\pm10)$ ps for the two 100 and two 300 $μ$m thick sensors respectively. These measurements are combined to a track time resolution of $(340\pm 5)$ ps.
