LHC的ALICE跃迁辐射探测器

The Transition Radiation Detector for ALICE at LHC

M. J. Kweon

摘要:

大型强子对撞机(LHC)ALICE实验的跃迁辐射探测器(TRD)可识别p+p中以及具有挑战性的高多重性重离子碰撞环境中的电子,并为ALICE Level 1触发提供快速在线跟踪。TRD被设计成具有出色的位置分辨率和π介子抑制能力。目前,18个TRD超级模块中的6个安装在ALICE中央桶中。2008年,安装了四个超级模块,并成功调试了利用宇宙射线轨迹的探测器。我们简要地描述了检测器的设计和报告的性能和目前的理解,基于这些数据的检测器。

英文摘要:

The Transition Radiation Detector (TRD) for the ALICE experiment at the Large Hadron Collider (LHC) identifies electrons in p+p and in the challenging high multiplicity environment of heavy-ion collisions and provides fast online tracking for the ALICE Level1 trigger. The TRD is designed to have excellent position resolution and pion rejection capability. Presently, six of the 18 TRD supermodules are installed in the ALICE central barrel. In 2008, four supermodules were installed and commissioning of the detector using cosmic ray tracks was successfully performed. We briefly describe the design of the detector and report on the performance and current understanding of the detector based on these data.
