文摘

Multi-gap Resistive Plate Chambers (MRPCs) were selected to construct the barrel Time of Flight (TOF) detector for the STAR experiments. Its mass production started in 2006. The production procedure and related quality control (QC) are described. A summary of the MRPC production status (2006–2008) and the test results with cosmic rays is given. With strict QC throughout the production process, over 95 % of the constructed MRPC modules meet the criteria required by STAR experiments.
