摘要：Aligning the CMS silicon tracker is an unprecedented challenge due to the more than 15 000
modules that it is composed of. Besides high precision mounting, survey measurements and the
laser alignment system, track based alignment is needed to reach the envisaged precision. The first
successful full scale alignment study on simulated data uses a fast global minimisation procedure
implemented in the Millepede II program. Tracks from cosmic ray muons and the inclusion of
prior knowledge are key ingredients. Experience beyond simulation studies is gained analysing
real data from cosmic ray muons.
