18 July 2006A.Ciocio -SCTSG5 Type IV Cables - Installation All type IV cables (2044+spares) going from PP3 racks in the ATLAS cavern to PS racks in US15 installed (+ connectors) Type IV going to USA15 almost completed –64 double harnesses to install (128 cables) –6 more days Testing in racks after installation and first cut ongoing Completed installation is expected in one week

18 July 2006A.Ciocio -SCTSG6 Type IV – Connectors in situ All connectors (2000+) in US15 completed on March 10 (a few were left but they are done now) Many racks are tested before and after plug into PS (Petr with Prague team) Very good yield but some rework was necessary One rack (the very first one made more than an year ago) needs cables rerouting (cables were cut too long by previous company) 2+1 CPE techs returned in mid-April for a few weeks –US side was reworked –Started 2 USA racks but left again because more USA15 racks were needed to be completed for the full team to operate efficiently A team of 6 techs (1 supervisor) will return this week Estimated completion of connectors in USA racks: End of August

18 July 2006A.Ciocio -SCTSG11 PS priorities
12
18 July 2006A.Ciocio -SCTSG12 Issues PP3 –We find problems as we plug in and test –Type IV all connected by end of July –Hopefully OK when Type III are connected Tester –Different flavor that work with different configuration of cable chain –Multiple laptops failure (~ok now) –Need help at CERN of experts (Ljubljana) when testing whole chain Defective dPPF1 –Some faulty cables were actually due to a bad channel on dPP1 (3 endcap 3 barrel) –Still missing some dPPF1 Connector in situ –Delay will move installation of PS later Need more HELP with testing until end of August (mid September)
