研制了一种用于RHIC/星星实验中快度大面积μ子望远镜探测器飞行时间测量的双间隙长读出带电阻板室（LMRPC）。LMRPC的有效面积为87 cm × 17 cm，10个250 μm的气隙排列成2个叠层，读出带宽2.5 cm，长90 cm。本文讨论了LMRPC设计中与其性能有关的考虑因素。原型LMRPC的宇宙线测试结果表明，探测效率>95%，时间分辨率≤ 70 ps。
A new kind (two end readout) of Multi-gap Resistive Plate Chamber with long readout-strip (LMRPC) is developed to be used at the large-area Muon Telescope Detector (MTD) at mid-rapidity at RHIC/STAR experiment for Time-of-Flight (TOF) measurement. The LMRPC has an active area of 87 cm × 17 cm, 10 gas gaps of 250 μm arranged in 2 stacks, with readout strips of 2.5 cm wide and 90 cm long. The considerations in LMRPC design related to its performance are discussed in this paper. The cosmic ray test results of a prototype LMRPC show a detection efficiency >95% and the time resolution ∼70 ps.
