For the muon trigger, three layers of thin-gap Resistive Plate Chambers (RPCs) will be added to the Barrel Inner (BI) region. This new generation of RPCs features a thin-gap design that significantly enhances their rate capabilities. However, it poses significant challenges for detector production, Quality Assurance and Quality Control. Our Chinese ATLAS group undertook the construction of 912 readout panels, the fabrication of 72 BI gas gaps, and the assembly of 360 singlets for the upgrade. To successfully implement the BI-RPC project in China, we have developed and refined a vacuum-bag-based method for producing honeycomb readout panels in our laboratory. This method is also utilized in the production of readout panels in the Chinese industry. The speed and quality of readout panel production have significantly improved. The procedures for gas gap production and the assembly of RPC singlets are outlined in detail. The gas gaps are treated with oil at a temperature of around 40 degrees Celsius and flushed with heptane before the application of linseed oil. This process can greatly enhance the quality of linseed oiling on the inner surfaces of the Bakelite RPC. The quality of the gas gaps is assessed and the results are very promising.</div></div>","PeriodicalId":19359,"journal":{"name":"Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment","volume":"1075 ","pages":"Article 170400"},"PeriodicalIF":1.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
