Present Tracker o 2014 main challenges: 1.All elements allowing safe operation of the tracker at low T need to be properly tested and commissioned in Tracker silicon strip to be re-commissioned at new low operating temperature. 3.New beam pipe to install + bake-out. This is crucial for the phase I Pixel upgrade detector as clearances and tolerances are minimal. 4.Present pixel detector to be re-installed after some minor repair work currently on-going, and re-commissioned at low temperature. July 7, 2013CDS - INFN - PADOVA48

Present Tracker o Jan-Feb: –Restart operation at P5 –In parallel tests DAQ with new TCDS (1) in B186 o March: 1 week global run o Mid April: beam pipe installation o End April: 4 weeks of CV maintenance → Tk OFF –in parallel: installation of DAQ 2 and new TCDS o End May: re-commission tracker with new DAQ2 and TCDS –global run with CMS as soon as tracker and XDAQ are ready o July: two mid-week global runs o July: Installation of the Pixel detector –Commissioning of the Pixel at low T (1) TCDS = trigger clock distribution system based on μTCA.

Present Tracker o Beginning of August: global run before closing CMS (likely a couple of weeks) o August: closing CMS and 3.8T magnetic field –Crucial point for testing dryness of the environment for cold operation (both silicon strips and Pixel) o End August – Mid September: 4 weeks of CRAFT o September– October: continue mid-week global runs o November: 4 weeks of cosmic challenge o December – January: getting ready for beam. August-December 2014 is also contingency time in case CMS needs to re-open. July 7, 2013CDS - INFN - PADOVA50
