Abstract

Over the next decade of LHC operation the instantaneous luminosity will reach up 7.5 times the design value with over 200 interactions per bunch-crossing. This will pose unprecedented challenges for the ATLAS trigger system.

We report on a prototype of the High Level Trigger software that maximizes commonality with offline reconstruction software while retaining the key aspects of trigger functionality including regional reconstruction and early event rejection. We report on the first experience of migrating trigger algorithms to this new framework and present the next steps towards a full implementation of the ATLAS trigger within AthenaMT.
