Development and test of the DAQ system to readout a Micromegas prototype installed into the ATLAS experiment — •Ourania Sidiropoulou — CERN, Switzerland and University of Würzburg, Germany

The Micromegas chambers have been chosen for the upgrade of the innermost forward muon tracking systems (Small Wheels) of the ATLAS detector in 2018-2019. A Micromegas quadruplet with an active area of 1m x 0.5m has been built at CERN as a prototype of the future Small Wheels detectors and is going to be tested in the ATLAS cavern environment during the LHC RUN-II period 2015-2017.

For the integration of this prototype detector into the ATLAS data acquisition system, an ATLAS compatible ReadOut Driver (ROD) based on the Scalable Readout System (SRS), the Scalable Readout Unit (SRU), will be used. A dedicated Micromegas segment has been implemented, in the framework of the ATLAS TDAQ online software, in order to include the detector inside the main ATLAS DAQ partition. A full set of tests, on the hardware and software aspects, is presented.
