Abstract

The invention discloses a high-counting-rate multi-gap resistive plate chamber detector. The high-counting-rate multi-gap resistive plate chamber detector comprises a plurality of MRPCs (multi-gap resistive plate chambers), at least one insulated baffle block which is used for mutually isolating the MRPCs by a preset distance, a plurality of connectors, two insulated films and two reading circuit boards, wherein at least one insulated baffle block and the MRPCs are arranged between the two insulated films, the two insulated films are arranged between the two reading circuit boards, and the two reading circuit boards are connected through the connectors. According to the high-counting-rate multi-gap resistive plate chamber detector, the MPRCs are spliced between the two reading circuit boards without being stacked, so that the cost is low, the needed space (or thickness) is small; moreover, the detecting efficiency for each MRPC can be as high as 95%, and the time resolution is superior to 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...
