Beam test of signal cross-talk and transmission for LMPRC

    Corresponding author: LI Cheng,

Abstract: A new prototype of large area Multi-gap Resistive Plate Chamber (MRPC) with long readout strips was built. This Long-strip Multi-gap Resistive Plate Chamber (LMRPC) is double stacked and has ten 250 μm-thick gas gaps. Signals are read out from the two ends of each strip with an active area of 50 cm×2.5 cm in each. The detector was tested at FOPI in GSI, using the secondary particles of proton beams (E=3.5 GeV) colliding with a Pb target. The results show that the LMRPC prototype has a time resolution of about 60-70 ps; the detecting efficiency is over 98% and the ratio of cross-talk is lower than 2%. The detector also has a good spatial resolution of 0.36 cm along the strip direction.
