The resulting stream of raw data at 3.5 TB/s has to be processed with a set of lossy and lossless compression and data reduction techniques to a storage data rate of 90 GB/s while preserving relevant data for physics analysis. This contribution presents a custom lossless data compression scheme based on entropy coding as the ﬁnal component in the data reduction chain which has to compress the data rate from 300 GB/s to 90 GB/s. A ﬂexible, multi-process architecture for the data compression scheme is proposed that seamlessly interfaces with the data reduction algorithms of earlier stages and allows to use parallel processing in order to keep the required ﬁrm real-time guarantees of the system. The data processed inside the compression process have a structure that allows the use of an rANS entropy coder with more resource eﬃcient static distribution tables. Extensions to the rANS entropy coder are introduced to eﬃciently work with these static distribution tables and large but sparse source alphabets consisting of up to 25 Bit per symbol. Preliminary performance results show compliance with the ﬁrm real-time requirements while oﬀering close-to-optimal data compression.","PeriodicalId":20428,"journal":{"name":"Proceedings of 40th International Conference on High Energy physics — PoS(ICHEP2020)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86825105","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}

Such beams have the potential to carry the search for new phenomena in lepton-antilepton collisions to extremely high energy and also to provide uniquely well-characterised neutrino beams. A muon beam may be created through the decay of pions produced in the interaction of a proton beam with a target. To produce a high-brightness beam from such a source requires that the phase space volume occupied by the muons be reduced (cooled). Ionization cooling is the novel technique by which it is proposed to cool the beam. The Muon Ionization Cooling Experiment collaboration has constructed a section of an ionization cooling cell and used it to provide the ﬁrst demonstration of ionization cooling. We present these ground-breaking measurements.","PeriodicalId":20428,"journal":{"name":"Proceedings of 40th International Conference on High Energy physics — PoS(ICHEP2020)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77300841","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}

After the ongoing long shutdown and eventually after LS3 in 2026, the accelerator luminosity will be increased up to 7 times as compared to design luminosity (1034 cm−2s−1). To meet the requirements of higher rates environment of HL-LHC era, the muon system of ATLAS detector needs to be upgraded. Therefore, the present small wheel will be replaced by the New Small Wheel, which will be constituted by MicroMegas micro-pattern gaseous detectors and small-strip Thin Gap Chambers. The methods adopted to achieve the challenging required geometrical precision of Micromegas chambers are presented. Specific measurement devices have been developed in the last few years to determine the mechanical metrology quality of Micromegas chambers, required for NSW. Planarity measurements of panels as well as modules after assembly are done with a specifically developed co-ordinate measuring machine. The methodology and the results will be presented. Results of in-plane measurements performed using Rasnik masks etched on the PCBs are also reported.","PeriodicalId":20428,"journal":{"name":"Proceedings of 40th International Conference on High Energy physics — PoS(ICHEP2020)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80086777","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}
