摘要：
The HL-LHC upgrade will significantly extend the collider's physics reach with the increased luminosity, and it poses challenging requirements on the performance of the detector, accordingly. To exploit its full physics potential, more selective hardware triggers are required. At the ATLAS experiment, a huge gain in the selectivity of the first-level muon trigger will be accomplished by incorporating the data of the precision tracking muon drift-tube (MDT) chambers into the online muon reconstruction in addition to the fast RPC (Resistive Plate Chambers) and TGC (Thin Gap Chamber) trigger chambers data. For this purpose, the Sector Logic system processing data from the trigger chambers will be complemented by the novel MDT trigger processor (MDTTP) boards.
