A Cosmic Ray Test Platform Based on the High Time Resolution MRPC Technology

In order to test the performance of detector prototypes in a: laboratory environment, we design and build a large area (90 cmx52 cm) test platform for cosmic rays based on a well-designed Multi-gap Resistive Plate Chamber (MRPC) with excellent time resolution and a high detection efficiency for minimum ionizing particles. The time resolution of the MRPC module used is tested to be similar to 80 ps, and the position resolution along the strip is mm, while the position resolution perpendicular to the strip is similar to 12.7 mm. The platform constructed by four MRPC modules can be used for tracking cosmic rays with a spatial resolution of similar to 6.3 mm, and provide a reference time similar to 40 ps.
