Description

The Monitored Drift Tube Trigger Processor (MDT-TP) will improve the rate capabilities of the first-level muon (L0 Muon) trigger of the ATLAS Experiment during the operation of the HL-LHC.

Preliminary information about a muon trigger candidate, obtained by other muon trigger subsystems, will be combined with the precision of the MDT chambers in order to improve the muon momentum resolution, while limiting the trigger rate to an acceptable level in the high-pileup environment of the HL-LHC.

The MDT-TP trigger logic is implemented on an AMD VU13P FPGA, where MDT hits are extracted around the region-of-interest identified by the trigger candidate and are used to perform muon reconstruction and transverse momentum estimation. For the events selected by the L0 trigger, MDT hits are transmitted by the MDT-TP to the ATLAS data acquisition system via FELIX. Monitoring, configuration and interfaces with other ATLAS subsystems are implemented via services running on an AMD Zynq SoM.

Several tests of the MDT-TP are being conducted, including the configuration and monitoring of the MDT-TP and the on-detector electronics, communication with other L0 Muon trigger boards, on-hardware validation of the trigger and readout logic and readout via FELIX. The current status of the prototype testing and the recent updates on gateware and software developments will be presented.
