The multi-gap resistive plate chamber detector provided by the embodiment of the invention has the advantages of large detection area, high applicability, low cost, small dead zone, high detection efficiency, small occupied space and the like.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a multi-air-gap resistive plate chamber detector. Background technique [0002] Multi-gap resistive plate chamber detector (Multi-gap Resistive Plate Chamber, MRPC) is a new type of gas detector. MRPC plays an important role in large baryon collision experiments due to its high time resolution, high detection efficiency and low cost. It plays an important role and is widely used in the construction of large time-of-flight devices in high-energy physics and nuclear physics experiments. It was first developed by the LHC-ALICE experimental group of CERN in 1996 and used in the ALICE time-of-flight detector on the Large Hadron Collider LHC. In addition, the STAR time-of-flight detector on the relativistic heavy ion collider RHIC and the time-of-flight detector of the CBM experiment on the FAIR device all use MRPC. [0003] The main structure of MRPC is glass electrode, ...
