18 July 2006A.Ciocio -SCTSG11 PS priorities

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)
