An 8-Channel ASD in 130 nm CMOS for ATLAS Muon Drift Tube Readout at the HL-LHC
/ Fras, Markus (Dresden, Max Planck Inst.) ; Abovyan, Sergey (Munich, Max Planck Inst.) ; Danielyan, Varuzhan (Munich, Max Planck Inst.) ; Kroha, Hubert (Munich, Max Planck Inst.) ; Nowak, Sebastian (Munich, Max Planck Inst.) ; Richter, Robert (Munich, Max Planck Inst.) ; Weber, Bradley (Munich, Max Planck Inst.) ; Zhao, Yazhou (Munich, Max Planck Inst.) ; Baschirotto, Andrea (Milan Bicocca U.) ; De Matteis, Marcello (Milan Bicocca U.) et al.
Spatial resolution and efficiency of the ATLAS muon Monitored Drift Tubes (MDT) depend on drift time resolution, noise levels, and accurate threshold setting. A new 130~nm readout device is developed and optimized for the required time resolution, to guarantee rise times below 10~ns with acceptable time slewing effects. [...]

Hardware Implementation of a Fast Algorithm for the Reconstruction of Muon Tracks in ATLAS Muon Drift-Tube Chambers for the First-Level Muon Trigger at the HL-LHC
/ Abovyan, Sergey (Munich, Max Planck Inst.) ; Danielyan, Varuzhan (Munich, Max Planck Inst.) ; Fras, Markus (Munich, Max Planck Inst.) ; Gadow, Philipp (Munich, Max Planck Inst.) ; Kortner, Oliver (Munich, Max Planck Inst.) ; Kortner, Sandra (Munich, Max Planck Inst.) ; Kroha, Hubert (Munich, Max Planck Inst.) ; Müller, Felix (Munich, Max Planck Inst.) ; Nowak, Sebastian (Munich, Max Planck Inst.) ; Richter, Robert (Munich, Max Planck Inst.) et al.
The High-Luminosity LHC will provide the unique opportunity to explore the nature of physics beyond the Standard Model of strong and electroweak interactions. Highly selective first level triggers are essential for the physics programme of the ATLAS experiment at the HL-LHC where the instantaneous luminosity will exceed the LHC Run 1 instantaneous luminosity by almost an order of magnitude.

An eight-channels 0.13-$\mu \text{m}$-CMOS front end for ATLAS muon-drift-tubes detectors
/ De Matteis, Marcello (Milan Bicocca U.) ; Resta, Federica (Milan Bicocca U.) ; Richter, Robert (Munich, Max Planck Inst.) ; Kroha, Hubert (Munich, Max Planck Inst.) ; Fras, Markus (Munich, Max Planck Inst.) ; Zhao, Yazhou (Munich, Max Planck Inst.) ; Abovyan, Sergey (Munich, Max Planck Inst.) ; Baschirotto, Andrea (Milan Bicocca U.)
Abstract: An eight-channel readout front end for Large Hadron Collider (LHC) ATLAS muon-drift-tubes detectors is hereby presented (defined 8 × AFE). The system is composed by the cascade of the analog signal processing front end and the Wilkinson A/D, performing both time-over-threshold and charge measurement. [...]

Optimization of the front-end electronics of Drift Tube chambers for high-rate operation
/ Schwegler, Philipp (Munich, Max Planck Inst.) ; Abovyan, Sergey (Munich, Max Planck Inst.) ; Danielyan, Varuzhan (Munich, Max Planck Inst.) ; Fink, David (Munich, Max Planck Inst.) ; Fras, Markus (Munich, Max Planck Inst.) ; Kortner, Oliver (Munich, Max Planck Inst.) ; Kroha, Hubert (Munich, Max Planck Inst.) ; Nowak, Sebastian (Munich, Max Planck Inst.) ; Ott, Sebastian (Munich, Max Planck Inst.) ; Richter, Robert (Munich, Max Planck Inst.) et al.
Monitored Drift Tube (MDT) chambers account for the vast majority of precision tracking chambers in the Muon Spectrometer of the ATLAS experiment at the Large Hadron Collider (LHC), where they have to sustain unprecedentedly high background radiation. New, so-called sMDT chambers with reduced tube diameter have been developed for operation at even higher rates, expected after the upgrade of the LHC to high luminosities (HL-LHC). [...]

Performance of the new amplifier-shaper-discriminator chip for the ATLAS MDT chambers at the HL-LHC
/ Kroha, Hubert (Munich, Max Planck Inst.) ; Abovyan, Sergey (Munich, Max Planck Inst.) ; Baschirotto, Andrea (Milan Bicocca U.) ; Danielyan, Varuzhan (Munich, Max Planck Inst.) ; Fras, Markus (Munich, Max Planck Inst.) ; Müller, Felix (Munich, Max Planck Inst.) ; Nowak, Sebastian (Munich, Max Planck Inst.) ; Resta, Federica (Milan Bicocca U.) ; De Matteis, Marcello (Milan Bicocca U.) ; Richter, Robert (Munich, Max Planck Inst.) et al.
The Phase-II Upgrade of the ATLAS Muon Detector requires new electronics for the readout of the MDT drift tubes. The first processing stage, the Amplifier-Shaper-Discriminator (ASD), determines the performance of the readout for crucial parameters like time resolution, gain uniformity, efficiency and noise rejection.

Optimisation of the Read-out Electronics of Muon Drift-Tube Chambers for Very High Background Rates at HL-LHC and Future Colliders
/ Nowak, Sebastian (Munich, Max Planck Inst.) ; Abovyan, Sergey (Munich, Max Planck Inst.) ; Gadow, Philipp (Munich, Max Planck Inst.) ; Ecker, Katharina (Munich, Max Planck Inst.) ; Fink, David (Munich, Max Planck Inst.) ; Fras, Markus (Munich, Max Planck Inst.) ; Kortner, Oliver (Munich, Max Planck Inst.) ; Kroha, Hubert (Munich, Max Planck Inst.) ; Müller, Felix (Munich, Max Planck Inst.) ; Richter, Robert (Munich, Max Planck Inst.) et al.
In the ATLAS Muon Spectrometer, Monitored Drift Tube (MDT) chambers and sMDT chambers with half of the tube diameter of the MDTs are used for precision muon track reconstruction. The sMDT chambers are designed for operation at high counting rates due to neutron and gamma background irradiation expected for the HL-LHC and future hadron colliders. [...]
