Abstract
In order to achieve sub-millimeter position resolution for tracking cosmic ray muon for building muon tomography system, a prototype of MRPC with narrow strips readout is designed and assembled. The width of readout pitch of the module is 2.54mm. Experiments by cosmic rays and X-rays have been carried out. After the calibration for each channel, the position is reconstructed by charge distribution across strips using central gravity. The results shows that the time resolution is about 50ps and the spatial resolution can reach 0.36mm. By this detector, we can not only get the muon track, but also get the muon momentum, which will provide more information for image reconstruction.
