A cosmic ray test platform based on high time resolution MRPC technology

【摘要】 In order to test the performance of detector prototypes in a laboratory environment, we design and build a large area(90 cm×52 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～80 ps, and the position resolution along the strip is～5mm, while the position resolution perpendicular to the strip is～12.7 mm. The platform constructed by four MRPC modules can be used for tracking cosmic rays with a spatial resolution of～6.3 mm, and provide a reference time～40 ps.更多还原
