Current Hardware Activities in ATLAS

ATLAS Phase-2 Upgrade

Taiwan's acticities in this area is a collaboration between Academia Sinica (AS) and National Tsing Hua University (NTHU).

Upgrade of the Muon Detector : Monitored Drift Tube (MDT)

• Upgrade readout electronics to provide information to Level-1 trigger to improve muon trigger efficiency
• Taiwan is contributing to building MDT mezzanine cards that process raw signals from detector
• The mezzanine card amplified/digitized/discriminate the signal, and extract arrival time.
• This effort is led by Prof. Suen Hou of Academia Sinica.

High Granularity Timing Detector (HGTD) :

• A precision timing detector to suppress pile-up in forward region
• Project currently under review, will subject to TDR approval this year
• AS+NTHU (led by Prof. Suen Hou) is contributing to the production of the electrical cables and optical fibers for readout.
• We are performing simulation to study the detector performance, and participating in test beam and analyzing the test beam data.
• AS group is coordinating the effort in implementing a production database for the HGTD.
