为在相对论重离子对撞机（RHIC）上进行的星星实验中的大面积μ子望远镜探测器（MTD）研制了一种新型的多间隙电阻板室（MRPC）。这些长读出条形多间隙电阻板室（MRPC）（LMRPC）具有87.0× 17.0cm 2的有效面积和10个250μ m厚的气隙排列成双叠层。每个读出条宽2.5厘米，长90厘米。信号在每个条带的两端读出。宇宙线测试表明，时间分辨率为1070 ps，探测效率大于95%。在费米实验室T963进行的束流测试表明，沿条带方向的时间分辨率为60- 70 ps，空间分辨率为沿着1 cm。
A new kind of Multi-gap Resistive Plate Chamber (MRPC) has been built for the large-area Muon Telescope Detector (MTD) for the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). These long read-out strip Multi-gap Resistive Plate Chambers (MRPCs) (LMRPCs) have an active area of 87.0×17.0cm2and ten 250μm-thick gas gaps arranged as a double stack. Each read-out strip is 2.5cm wide and 90cm long. The signals are read-out at both ends of each strip. Cosmic ray tests indicate a time resolution of ∼70ps and a detection efficiency of greater than 95%. Beam tests performed at T963 at Fermilab indicate a time resolution of 60–70ps and a spatial resolution of ∼1cm along the strip direction.
