Abstract
The design and performance of the inner detector trigger for the high level
trigger of the ATLAS experiment at the Large Hadron Collider during the 2016-18
data taking period is discussed. In 2016, 2017, and 2018 the ATLAS detector
recorded 35.6 fb$^{-1}$, 46.9 fb$^{-1}$, and 60.6 fb$^{-1}$ respectively of
proton-proton collision data at a centre-of-mass energy of 13 TeV. In order to
deal with the very high interaction multiplicities per bunch crossing expected
with the 13 TeV collisions the inner detector trigger was redesigned during the
long shutdown of the Large Hadron Collider from 2013 until 2015. An overview of
these developments is provided and the performance of the tracking in the
trigger for the muon, electron, tau and $b$-jet signatures is discussed. The
high performance of the inner detector trigger with these extreme interaction
multiplicities demonstrates how the inner detector tracking continues to lie at
the heart of the trigger performance and is essential in enabling the ATLAS
physics programme.
