DAQ and constructional aspects of a burn-in crate for the ATLAS ITk strips end-cap — •Ben Brüers — DESY Zeuthen
For the high luminosity phase of the LHC, the ATLAS collaboration plans to upgrade its current tracking detector with a new, all silicon pixel and strip detector, referred to as Inner Tracker (ITk). The ITk will consist of cylindrical layers in the centre (barrel) and concentric discs on either side of the barrel (end-caps). Large parts (a surface area of 162 m2) of the ITk will be populated with silicon strip sensors. Read-out chips (ABCStar, HCCStar and AMAC) and some other components will be hosted on printed circuit flex boards (hybrids and power-boards). To reduce the risk of hybrid failure in the finalised ITk detector due to infant mortality, all hybrids are tested intensively for 100 hours at 40∘C after production. Only hybrids fulfilling certain quality criteria are installed in ATLAS later. This procedure, called burn-in, will be performed in crates allowing to reach the designed production rates. This talk will summarise the progress of the development of an end-cap hybrid burn-in crate, focussing on DAQ and constructional aspects.
