Alignment of the Inner Tracker stations using beam--dump and cosmics data.

Abstract

First studies of the alignment of the Inner Tracker stations using real data is described. The two side boxes have been aligned using both the cosmics data accumulated over the Summer of 2008 and with the beam--dump data (TED data) collected mid-september 2008. The top and bottom boxes on their sides have been aligned with the beam--dump data only. To validate the results obtained with the TED data, studies have also been performed with Monte Carlo simulated events of $20~\mathrm{GeV}$ muons with large occupancy in the Inner Tracker stations.

Plots

This is very much work in progress. These plots correspond to the results shown in the Alignment meeting 15/4/09. See slides
