RHIC的STAR实验计划实施一个60平方米的飞行时间(TOF)系统。多间隙电阻板室(MRPC)具有高达60ps的时间分辨率和97%以上的效率，是STAR TOF系统的理想选择。我们用6个220cm2的气隙和20cm2的焊盘面积组成的模块得到了这一结果。在本文中，我们报告了这种MRPC组件的性能，并介绍了原型托盘星形结构和安装的现状。
The STAR experiment at RHIC plans to implement a 60 m2Time-of-Flight (TOF) system. The Multigap Resistive Plate Chamber (MRPC) is a suitable candidate for the STAR TOF system due to its time resolution of order of 60 ps with efficiencies in excess of 97%. We obtained this result with modules composed of 6 gas gaps of 220 μm and pad area of 20 cm2. In this paper, we report on the performance of this MRPC module and present the current status of the construction and installation into STAR of a prototype tray.
