CMS电磁量能器的时间重构与性能

Time Reconstruction and Performance of the CMS Electromagnetic Calorimeter

CMS Collaboration

摘要:

本文以实验束电子、宇宙射线和束生μ子为例,研究了CMS电磁量能器时间测量的分辨率和线性度。由此产生的时间分辨率测量钨酸铅晶体是优于100 ps的能量存款大于10 GeV。晶体与晶体的同步精度为500 ps,是使用2008年第一个LHC光束产生的μ子进行的。

英文摘要:

The resolution and the linearity of time measurements made with the CMS electromagnetic calorimeter are studied with samples of data from test beam electrons, cosmic rays, and beam-produced muons. The resulting time resolution measured by lead tungstate crystals is better than 100 ps for energy deposits larger than 10 GeV. Crystal-to-crystal synchronization with a precision of 500 ps is performed using muons produced with the first LHC beams in 2008.
