CSC Status A preliminary overview of the Phase1

CSC Status • A preliminary overview of the Phase#1 lessons and plans for Phase#2 was given during the Run Meeting on September 1 st. – http: //indico. cern. ch/get. File. py/access? sub. Cont. Id=8& contrib. Id=4& amp; res. Id=1& material. Id=slides& conf. Id=4246 • CMS detector has been reopend – endcaps are moved all the way to towards the pit. – potential internal damage to a few chambers after magnetized dowel pins dropped on and dented a couple of chambers has been investigated: no problems observed – disconnected connectors on a couple of ME 1/1 chambers turned out to be caused by magnetized strain reliefs: all strain reliefs for the six MTCC chambers have been replaced; the rest will follow. – services are back online: gas, HV, cooling and LV • A 3 rd Maraton LV supply will be introduced in order to increase the overall LV capacity. – ready to continue stand-alone operations until the closure (planned for the 1 st week of October)

CSC Status (cont’d) • Pre-Phase#2 work, in progress – in local DQM/offline analysis a list of chambers identified that need to be verified • single chamber runs – verify chamber timing • e. g. compensate for different lengths in AFEB-to-ALCT cables • verify chamber-to-chamber timing – verify firmware fixes that solve various issues that showed up in the data • e. g. anode-wire starting at 1 for all chambers – Monitor Maraton LV supplies for any power glitches – Include Track. Finder DAQ readout in the Local DAQ.
