星星时间投影室（TPC）是相对论重离子对撞机上用来记录碰撞过程的装置。TPC是围绕交互顶点的一套探测器中的中心元件。TPC提供围绕束线的完全覆盖，并且提供对质心系的伪快度的+/-1.8单位内的带电粒子的完全跟踪。记录到动量大于100 MeV/c的带电粒子。每个事件超过3000个轨迹的多重性在软件中常规重建。TPC直径4米，长4.2米，是世界上最大的TPC。(C)2002 Elsevier Science B. V.保留所有权利。
The STAR Time Projection Chamber (TPC) is used to record the collisions at the Relativistic Heavy Ion Collider. The TPC is the central element in a suite of detectors that surrounds the interaction vertex. The TPC provides complete coverage around the beam-line, and provides complete tracking for charged particles within +/- 1.8 units of pseudo-rapidity of the center-of-mass frame. Charged particles with momenta greater than 100 MeV/c are recorded. Multiplicities in excess of 3000 tracks per event are routinely reconstructed in the software. The TPC measures 4 m in diameter by 4.2 m long, making it the largest TPC in the world. (C) 2002 Elsevier Science B.V. All rights reserved.
