First Alignment of the Inner Tracker using data from the TI-8 Sector Test LHCb-2009-030

 

Abstract

A first software alignment of the Inner Tracker using data from the LHC synchronization test is described. Residual plots are used to adjust the position of the Inner Tracker boxes and layers in the x-direction and to verify the correctness of the survey data. With the corrections determined in this note the position of the x-measuring ladders is known to a precision of $100~\mu$m or better.
