Beam test of signal cross-talk and transmission for LMPRC

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 $\mu$m-thick gas gaps. Signals are read out from two ends of strip with an active area of 50 cm$\times$2.5 cm in each. The detector was tested at FOPI in GSI, using the secondary particles of proton beams ($E=3.5GeV$) colliding with a Pb target. The results show that the LMRPC prototype has a time resolution of about 60$\sim$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.
