Performance testing of a long-strip two-end readout multi-gap resistive plate chamber

Multi-gap Resistive Plate Chamber (MRPC) is a new generation of gas detector with good tim-ing and spacial resolution, whose technique is widely applied in some recent high energy (nuclear) physics experiments. In this letter, we report a long-strip two-end readout MRPC and its test beam performance. The measurements show that the long-strip performs a transmission line characteristic and the impedance is independent of the length of strip. The MRPC module we developed is presented to gain a timing resolution of ～80 ps and a spacial resolution of ～6.4 mm. The possible application of the MRPC is also discussed.
