SUMMARY:Construction and commissioning of the ATLAS new small wheel
DESCRIPTION:The ATLAS experiment is currently upgrading the first muon station in the high-rapidity region with the New Small Wheels (NSW)\, based on large-size multi-gap resistive strips Micromegas technology and small-strip Thin Gap Chambers (sTGC). The NSW system is going to be installed in the ATLAS underground cavern during the LHC long shutdown 2 (2021) to enter in operation for Run3 (starting in February 2022). 128 Micromegas quadruplets\, each composed by four measurement layers two square meters in size\, are needed to build the two New Small Wheels\, covering a total active area of about 1280 m2. The construction of all MM modules\, carried out in France\, Germany\, Italy\, Russia and Greece\, is completed. Their mechanical integration into sectors\, the installation of on-detector services and electronics\, along with all validation and acceptance tests\, have also been completed for the first NSW. The preparation of the second NSW is very well advanced. The status of the project\, in view of the imminent installation of the two NSW in ATLAS by the fall of 2021 will be reported. The integration workflow of Micromegas detector into sectors will be described and the results obtained with cosmic rays data during the final validation tests will be presented. Finally\, the impressive steps of the wheel assembly completion\, will be shown. \n  \nMore ways to join: \n\nJoin from the meeting link \nhttps://infn-lnf.webex.com/infn-lnf/j.php?MTID=mccfa590852bcf2973b74223ef7178a98 \nJoin by meeting number \nMeeting number (access code): 152 673 7038 \nMeeting password: 05082021
