Improved performance of the LHCb Outer Tracker in LHC Run 2

Understand

The LHCb Outer Tracker is a gaseous detector covering an area of $5\times 6 m^2$ with 12 double layers of straw tubes.

• The performance of the detector is presented based on data of the LHC Run 2 running period from 2015 and 2016.
• Occupancies and operational experience for data collected in $p p$, pPb and PbPb collisions are described.
• An updated study of the ageing effects is presented showing no signs of gain deterioration or other radiation damage effects.
