摘要

- ALICE@LHC是一个研究重离子碰撞(Pb-Pb高达5.5 ATeV)的优化实验。主要目的是寻找一种新的物质状态(称为QGP),其中夸克和胶子被定义。粒子识别是由一组探测器保证的:其中,飞行时间系统在识别动量范围[0.5,4]GeV/c的带电强子(π, K, p)方面起着重要作用。宇宙射线的第一个数据采集周期是检查实验装置和开发的用于描述、模拟、重建、可视化和分析的软件性能的好机会。对这些宇宙射线数据进行了初步的时间分辨率研究。

The TOF detector of ALICE experiment: Analysis of the first cosmic data
— ALICE@LHC is an experiment optimized for study of heavy-ions collisions (Pb-Pb up to 5.5 ATeV). The main aim is the search for a new state of matter (called QGP) where quarks and gluons are deconfined. Particle identification is guaranteed by a set of detectors: one of these, the time-of-flight system plays an important role in the identification of charged hadrons (π, K, p) in the momentum range [0.5, 4] GeV/c. The first data-taking periods with cosmic rays have been a great chance to check the performance of the experimental apparatus and of the developed software for description, simulation, recostruction, visualization and analysis. A preliminary time resolution study on this cosmic rays data is presented.
