Problems solved by technology

[0005] In order to overcome the problem that the spacer (spacer) in the existing resistive plate chamber detector (RPC) is easy to be glued and the dead zone is large, the present invention designs a new type of resistive plate chamber detector, which not only Abandoning the traditional sealing gasket, there is no problem of glue opening, and the detection dead zone is smaller than that of the sealing gasket, and the air gap uniformity is better

Embodiment Construction

[0022] The present invention provides a novel resistive plate chamber detector. The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] The structure of the present invention is as figure 1 As shown, several polyethylene tetrafluoro tubes 1 are arranged side by side, and each polyethylene tetrafluoro tube 1 is divided into multiple sections, which are threaded on a nylon wire 2 in sequence, and adhesive glue is injected into the polyethylene tetrafluoro tube 1 to make It is fixed on the nylon thread 2. The diameter of the polyethylene tetrafluoro tube 1 is 2 mm, the distance between each polyethylene tetrafluoro tube is 80-100 mm, and the length of each segment of the polyethylene tetrafluoro tube is 5-12 mm. The polyethylene tetrafluoro tube 1 is used as the sealing gasket of the resistive plate chamber detector, sandwiched between two pieces of float glass 4, and the outer sides of the two pieces...

Abstract

The invention relates to a novel resistive plate chamber detector and belongs to the technical field of radiation detection. A polyethylene tube sleeving a nylon wire is fixed between two parallel pieces of resistive glass, a graphite layer and a circuit board at the outer sides of the glass are insulated and separated from each other by a Mylar membrane, and a honeycomb plate for supporting and fixing is connected to the outer side of the circuit board. The novel resistive plate chamber detector is put in an airtight gas flow box in working. The resistive plate chamber detector does not comprise a traditional sealing gasket and thus is free of the problem of glue failure, and a detection dead region caused by the novel resistive plate chamber detector is smaller than that caused by the sealing gasket, and moreover, the novel resistive plate chamber detector is better in air gas uniformity.

Description

technical field [0001] The invention relates to a novel resistive plate chamber detector, which belongs to the technical field of radiation detection. Background technique [0002] Since RPC was invented in the 1980s, it has been widely used in the fields of high-energy physics and nuclear physics experiments due to its simple and robust structure, high detection efficiency, and superior time and space performance. Such as the BaBar experiment in the SLAC National Accelerator Laboratory in the United States, the CMS and ATLAS detectors on the Large Hadron Collider (LHC) built by the European Organization for Nuclear Research (CERN), and the ARGO-YBJ cosmic ray in Yangbajing, Tibet. Experiments, etc., use a lot of RPC. [0003] RPC is a parallel plate gas detector, generally composed of two layers of high-impedance parallel electrode plates, leaving a gap of 2 mm in the middle to fill the working gas; the outer surface of the electrode plate is covered with resistive electro...
