It\u0000utilises ~100 t of low radioactivity argon from an underground source (UAr) in\u0000its inner detector, with half serving as target in a dual-phase time projection\u0000chamber (TPC). The UAr cryogenics system must maintain stable thermodynamic\u0000conditions throughout the experiment's lifetime of >10 years. Continuous\u0000removal of impurities and radon from the UAr is essential for maximising signal\u0000yield and mitigating background. We are developing an efficient and powerful\u0000cryogenics system with a gas purification loop with a target circulation rate\u0000of 1000 slpm. Central to its design is a condenser operated with liquid\u0000nitrogen which is paired with a gas heat exchanger cascade, delivering a\u0000combined cooling power of >8 kW. Here we present the design choices in view of\u0000the DS-20k requirements, in particular the condenser's working principle and\u0000the cooling control, and we show test results obtained with a dedicated\u0000benchmarking platform at CERN and LNGS. We find that the thermal efficiency of\u0000the recirculation loop, defined in terms of nitrogen consumption per argon flow\u0000rate, is 95 % and the pressure in the test cryostat can be maintained within\u0000$pm$(0.1-0.2) mbar. We further detail a 5-day cool-down procedure of the test\u0000cryostat, maintaining a cooling rate typically within -2 K/h, as required for\u0000the DS-20k inner detector. Additionally, we assess the circuit's flow\u0000resistance, and the heat transfer capabilities of two heat exchanger geometries\u0000for argon phase change, used to provide gas for recirculation. We conclude by\u0000discussing how our findings influence the finalisation of the system design,\u0000including necessary modifications to meet requirements and ongoing testing\u0000activities.","PeriodicalId":501374,"journal":{"name":"arXiv - PHYS - Instrumentation and Detectors","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The measured $^8$B solar neutrino flux of\u0000$(4.7_{-2.3}^{+3.6})times 10^6,mathrm{cm}^{-2}mathrm{s}^{-1}$ is consistent\u0000with results from dedicated solar neutrino experiments. The measured neutrino\u0000flux-weighted CE$nu$NS cross-section on Xe of\u0000$(1.1^{+0.8}_{-0.5})times10^{-39},mathrm{cm}^2$ is consistent with the\u0000Standard Model prediction. This is the first direct measurement of nuclear\u0000recoils from solar neutrinos with a dark matter detector.","PeriodicalId":501374,"journal":{"name":"arXiv - PHYS - Instrumentation and Detectors","volume":"161 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141935025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first application of MAPS\u0000in high energy physics has been the PXL detector, installed in 2014 as the\u0000vertexer of the STAR experiment at BNL. In the same years, ALICE Collaboration\u0000started the development of a new MAPS with improved performances, to assemble a\u0000new detector to replace the Inner Tracking System used during LHC Run 1 and 2.\u0000This effort lead to the ALPIDE sensor, today successfully equipped in a large\u0000variety of systems. Starting from 2019, profiting from the experience acquired\u0000during the design of the ALPIDE sensor, the ALICE Collaboration embarked on a\u0000new development phase, the ITS3 project. Here the goal is to design the first\u0000truly cylindrical detector based on wafer-size sensors in 65 nm CMOS node. This\u0000new detector is expected to take data during LHC Run 4. ALICE Collaboration\u0000submitted a proposal for a new experiment, to be installed in place of the\u0000present detector system before the LHC Run 5. Building on the experience on\u0000MAPS acquired in the recent years, the idea is to design a compact all silicon\u0000detector, that will give unprecedented insight into the quark-gluon plasma\u0000characterization.","PeriodicalId":501374,"journal":{"name":"arXiv - PHYS - Instrumentation and Detectors","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141935032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
