Abstract

The invention discloses a high-counting-rate multi-air-gap resistive plate chamber detector, which comprises: a plurality of MRPCs; at least one insulating stopper, at least one insulating stopper is used to separate the plurality of MRPCs from each other by a predetermined distance; a plurality of MRPCs Connector; two insulating films and two readout circuit boards, at least one insulating stopper and a plurality of MRPCs between the two insulating films, two insulating films between the two readout circuit boards, two readout The circuit boards are connected by a number of connectors. In the high count rate multi-air-gap resistive plate chamber detector of the present invention, multiple MRPCs are spliced ​​between two readout circuit boards, without stacking, low cost, small required space (or thickness), and the detection efficiency of each MRPC Can be as high as 95%, with a time resolution better than 100ps.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a high count rate multi-air-gap resistive plate chamber detector. Background technique [0002] The multi-gap resistive plate chamber detector (Multi-gap Resistive Plate Chamber, MRPC) is a new type of gas detector, which was first developed by the LHC-ALICE experimental group of CERN in 1996. Due to its excellent time performance, simple structure, cheap materials, and ease of large-area use and mass production, it is widely used in the construction of large time-of-flight devices in high-energy physics and nuclear physics experiments. For example, in addition to the ALICE time-of-flight detector on the Large Hadron Collider LHC, there are also the STAR time-of-flight detector on the Relativistic Heavy Ion Collider RHIC and the time-of-flight detector used for CBM experiments on the FAIR device. [0003] MRPC is mainly composed of glass electrodes, narrow air gap, i...
