SLHC一级触发的像素检测器

A Pixel Detector for Level-1 Triggering at SLHC

J. Jones, G. Hall, C. Foudas, A. Rose

摘要:

我们报告的初步设计研究的像素探测器CMS在超级大型强子对撞机。这些研究的目的是调查设计内部跟踪器像素探测器的可能性,其数据可用于在第一级触发时选择事件。所考虑的检测器由两层20 × 50 × 10 μ m3的像素组成,彼此径向非常接近,使得两层之间的命中的重合相当于轨道横向动量(pT)切割。这种削减减少了大量的低动量数据预计在SLHC,同时保持跟踪效率非常高的高pT轨道。这种探测器的性能的初步结果。

英文摘要:

We report on preliminary design studies of a pixel detector for CMS at the Super-LHC. The goal of these studies was to investigate the possibility of designing an inner tracker pixel detector whose data could be used for selecting events at the First Level Trigger. The detector considered consists of two layers of 20x50x10 um3 pixels at very close radial proximity from each other so that coincidences of hits between the two layers amount to a track transverse momentum (pT) cut. This cut reduces the large amount of low-momentum data expected at SLHC while keeping the tracking efficiency very high for the high pT tracks. Preliminary results on the performance of such a detector are presented.
