Query: Performance of the new Readout Electronics for the ATLAS (s)MDT Chambers
  and Future Colliders at High Background Rates   Small-diameter Drift Tube (sMDT) detectors with 15 mm tube diameter have
proven to be excellent candidates for precision muon tracking detectors in
experiments at future hadron colliders like HL-LHC and FCC-hh where
unprecedentedly high background rate capabilities are required. sMDT chambers
are currently being installed in the inner barrel layer of the ATLAS muon
spectrometer. The rate capability of the sMDT drift tubes in terms of muon
detection efficiency and spatial resolution is limited by the performance of
the readout electronics. A new (s)MDT ASD (Amplifier-Shaper-Discriminator)
readout chip for use at the HL-LHC and future hadron colliders with a faster
peaking time compared to the old chip has been developed, reducing the
discriminator threshold crossing time jitter and thus improving the time- and
spatial resolution with and without $\gamma$-background radiation.
Additionally, a method compensating the gas gain drop due to space charge at
high $\gamma$-background hit flux by adjusting the sMDT operating voltage will
be presented. Simulations show, that the addition of active baseline
restoration circuits in the front-end electronics chips in order to suppress
signal-pile-up effects at high counting rates further leads to significant
improvement of both efficiency and resolution. Extensive tests using sMDT test
chambers have been performed at the CERN Gamma Irradiation Facility (GIF++).
Chambers equipped with new readout chips with improved pulse shaping and
discrete readout circuits with baseline restoring functionality have been
tested.
