ATLAS Lecce group is taking part to this experiment since its birth in the ’90’s. The group has designed, built, installed and tested the detectors which give the muon trigger in the barrel region of the apparatus, the Resistive Plate Chambers (RPC). For these detectors we also have taken care of the cabling and the geometric description, of the data decoding, the monitoring and data quality assessment, as well as timing and performance measurement.  We have given a relevant contributions to the study, the development and the performances measurement of the muon High Level Trigger. Last but not least we work on the development of the methodologies and the techniques needed for the Physics Data Analysis. In particular we are interested in the discovery of SuperSymmetric (SUSY) particles and in the measurement of their characteristics (as for example the spin), as well as searching for Exotics production.

A new item regards the Micromegas gas Chambers which will be installed for the Phase I LHC upgrade for which we designed and we are building part of the mechanics structure, while participating to the Micromegas/sTGC integration at CERN for the New Small Wheel Project.  Finally we are involved in the new Phase II upgrade project, which is the construction of a new inner tracker (ITK), where Lecce group will be heavily involved for the construction and test.

Finally we run and maintain a Tier3 Grid Cluster where both our group and any other group from all the ATLAS Collaboration can run their analysis jobs and Montecarlo simulations having the power of the Grid at their hands.
