On March 30th at 12.58 LHC delivered to CMS for the first time 7 TeV Ecm collisions. CMS and the Tracker were fully operational and collected about 210.000 Minimum Bias events in ~ 2 hours during the first fill. Everything worked very well, the quality of the data and the performance of the Tracker were excellent, the feedback from the offline was ultra-rapid. The start-up of data taking at 7 TeV Ecm looks thus very good, but this is going to be a long journey! I would like to take this opportunity to thank everyone and the teams that have worked very hard over the last few months of shutdown to improve and consolidate the Tracker, its systems and infrastructures.
