摘要
本文描述了ALICE时间投影室(TPC)的设计、建造和调试。它是CERN LHC上ALICE实验中用于带电粒子模式识别、径迹重建和鉴别的核心设备。TPC呈圆柱形，体积接近90 m^3，在平行于其轴线的0.5 T螺线管磁场中运行。本文详细描述了该探测器在LHC能量下中心Pb-Pb碰撞极端多重数环境中运行的设计考虑。将由此产生的需求实现为硬件（场笼、读出室、电子学）、基础设施（气体和冷却系统、激光校准系统）和软件，带来了许多技术创新，本文对这些创新以及探测器所有主要组件的当前实现进行了描述。我们还报告了完成第一轮独立校准运行后所达到的性能，并展示了接近TPC技术设计报告中规定的指标的结果。
