CMS带材跟踪器安装前的性能研究

Performance studies of the CMS Strip Tracker before installation

CMS Tracker Collaboration

摘要:

2007年3月,在欧洲核子研究中心的跟踪器集成设施完成了硅带跟踪器的组装。近15%的探测器使用电缆,纤维光学,电源和电子设备用于LHC的操作。使用局部冷却器来循环冷却剂以进行低温操作。为了了解条带跟踪器模块的效率和对准,实施了宇宙射线触发。从3月到7月,记录了450万次触发。这段时间被称为部门测试,提供了跟踪器操作的实际经验,特别是安全、数据采集、电力和冷却系统。本文描述了在扇形试验期间带材系统的性能,该试验由五个由冷却剂温度定义的不同时期组成。重要的重点是放在从蒙特卡洛研究的数据和结果之间的比较。

英文摘要:

In March 2007 the assembly of the Silicon Strip Tracker was completed at the Tracker Integration Facility at CERN. Nearly 15% of the detector was instrumented using cables, fiber optics, power supplies, and electronics intended for the operation at the LHC. A local chiller was used to circulate the coolant for low temperature operation. In order to understand the efficiency and alignment of the strip tracker modules, a cosmic ray trigger was implemented. From March through July 4.5 million triggers were recorded. This period, referred to as the Sector Test, provided practical experience with the operation of the Tracker, especially safety, data acquisition, power, and cooling systems. This paper describes the performance of the strip system during the Sector Test, which consisted of five distinct periods defined by the coolant temperature. Significant emphasis is placed on comparisons between the data and results from Monte Carlo studies.
