Development of a tester hardware tool for new-read electronic cards of the MDT detectors of the ATLAS muon spectrometer for the Phase-II upgrade — •Mathias Modlmayr, Gia Khoriauli, and Raimund Ströhmer — University of Würzburg

The monitored drift tube detectors (MDT) are part of the ATLAS muon spectrometer. The MDT segments (chambers) are read-out with on-chamber mezzanine cards. The cards are equipped with signal amplifier-shaper-discriminator and time to digital converter chips. For the LHC Phase-II upgrade, these cards are planned to be replaced with the new mezzanine cards currently being developed. The new MDT read-out is essential to cope with the increased particle rates at the High-Luminosity LHC. Moreover, the MDT will be part of the ATLAS hardware-based trigger system. Therefore, one of the new requirements to the new mezzanine cards is to operate in a triggerless read-out mode as well as to keep a triggered read-out mode as an option.

We develop a hardware tool, which will be used in the quality mass tests of the new mezzanine cards. The main goal of the tool is to test all functionalities and the stability of the new mezzanine cards and certify them. Also, efficiencies, noise rates, crosstalk, resolution and linearity of time measurements and some more characteristics of the mezzanine cards will be measured and documented in a dedicated database. The current status of the development of the tester tool and the test procedures are presented.
