Thick gas electron multiplier having multilayer-structure single film

Abstract

The application discloses a thick gas electron multiplier having a multilayer-structure single film. The thick gas electron multiplier comprises a membrane plate formed by alternating lamination of copper layers and insulating layers; the copper layers and the insulating layers are in tight contact; and the copper layers are arranged at the bottom and top of the membrane plate. A plurality of through straight holes are formed in the membrane plate and penetrate the top layer and the bottom layer; and insulating rings are arranged at the inner walls of the through straight holes and are used for isolating the copper layers from the inner cavities of the through straight holes. Because the membrane plate formed by alternating lamination of copper layers and insulating layers is arranged andthe copper layers and the insulating layers are in tight contact, the through zone formed between the conventional multilayer superposed structures is removed and thus the thickness of the multi-layerstructure is reduced; and the through straight holes are formed in the membrane plate in an overall manner and thus hole alignment is ensured and deformation and parallelism between layers are the same, so that problems of misalignment of the holes of the multi-layer structure and large multi-layer deformation and parallelism difference are solved.

Description

Technical field [0001] The present disclosure generally relates to the field of particle physics experiments and radiation detection, in particular to the field of gas detectors, and in particular to a thick gas electron multiplier with a single film with a multilayer structure. Background technique [0002] In the fields of particle physics experiments (ie high-energy physics experiments) and radiation detection, gas detectors are important detection methods. The latest development direction of gas detectors is Micro-Pattern Gaseous Detector (MPGD), such as gas electron multiplier (Gaseous Electron Multiplier, GEM), thick gas electron multiplier (thick GEM), MicroMegas (MM), etc. Among them, the thick GEM is a relatively comprehensive microstructure gas detector developed in China. It has not only realized localization, but also has developed diversified. Thick GEM has the advantages of high gain, low cost, strong and durable. With the application of thick GEM in the TPC track...
