论文摘要
爱丽丝(Alice)是针对重型离子碰撞中产生的强相互作用物质的研究,并致力于夸克 - 胶原等离子体的表征。为了实现LHC运行3的物理计划,正在进行实验设备的重大升级。升级的一个关键要素是用全新的基于硅的检测器(其2)替换内部跟踪系统(ITS),其功能将允许重建稀有物理通道,而以前的布局无法访问。这种提高性能的能力是采用定制设计的CMOS单片主动像素传感器作为检测元素。在本程序中,将概述采用的技术以及检测器调试的状态。
ALICE is the CERN LHC experiment optimised for the study of the strongly interacting matter produced in heavy-ion collisions and devoted to the characterisation of the quark-gluon plasma. To achieve the physics program for LHC Run 3, a major upgrade of the experimental apparatus is ongoing. A key element of the upgrade is the substitution of the Inner Tracking System (ITS) with a completely new silicon-based detector (ITS 2) whose features will allow the reconstruction of rare physics channels not accessible with the previous layout. The enabling technology for such a performance boost is the adoption of custom-designed CMOS Monolithic Active Pixel Sensor as detecting elements. In this proceedings, an overview of the adopted technologies as well as the status of the detector commissioning will be given.
