Description
The ATLAS collaboration selected Micromegas (MM) technology and small-strip Thin Gap Chambers for the upgrade of the first muon station in the high-rapidity region. The modules of MM and sTGC are being integred at CERN with installation, testing and validation of on-detector electronics & readout chain for a system with more than 2.1 M electronic channels. These include ~4K MM Front-End Boards, custom printed circuit boards with 64-channel VMM ASICs that interface with the Trigger and Data Acquisition system through ~1K data-driver Cards (ADDC & L1DDC, respectively). The readout chain is based on optical link technology (GigaBit Transceiver links) connecting the backend to the front-end electronics via the Front-End LInk eXchange (FELIX), is a system to be used for the next generation ATLAS read out driver. Experience and performance results from the first large-scale electronics integration tests on final MM wedges, including system validation with cosmic-rays, will be presented.
