1. 25 October 2005A.Ciocio - SCTSG1 Type IV Cables and PP3 Status & Plan

2. 25 October 2005A.Ciocio - SCTSG2 PP3 Racks in UX15 (US15 side) Y.52-4.X7, Y.53-4.X7 Y.52-1.X6, Y.46-1.X6 Y.43-1.X6, Y.34-1.X6 Y.51-2.X2, Y.52-2.X2 Y.53-2.X2

3. 25 October 2005A.Ciocio - SCTSG3 PP3 Racks in UX15 (USA15 side) Y.51-23.X8 Y.52-23.X8 Y.53-23.X8 Y.51-26.X5, Y.53-26.X5 Y.52-25.X2, Y.53-25.X2 Y.51-25.X1

5. 25 October 2005A.Ciocio - SCTSG5 Status of Type IV cables Type IV cables are delivered in double lengths with connectors installed at the PP3 end and pulled between the UX15 cavern and the US(A) halls US side completed USA side installation started this week Delivery of harness has been very slow –Vacation and QA problems in the summer –Connectors quality –Delay of components delivery from CERN to company –Bobbins damage –Production stopped for 3 weeks Delivery restored this week with expected rate of 150 double harness/week Expected complete delivery of harnesses by the end of the year Installation of type IV might be interrupted by installation of type ii/iii UX side US(A ) side PP3Power Supply

6. 25 October 2005A.Ciocio - SCTSG6 Mapping Mapping/layout subject to frequent adjustements to accommodate changes in routing or discrepancies with original expected routing Endcap mapping issue –In the present mapping, six PS crates from each cavern are shared between the two endcaps –The endcap interlock scheme requires four matrix cards per cavern –The full set of interlock signals from one quadrant will be connected to one matrix card –the present mapping may be accommodated by the interlock hardware by routing signals between matrix cards –PS channel skipping to better match the interlock modularity of 4 to the modularity of the cooling system –Revision of the DCS system to accommodate modules from multiple partitions within one PS crate

7. 25 October 2005A.Ciocio - SCTSG7 US(A) racks

8. 25 October 2005A.Ciocio - SCTSG8 In US15 Cut cables and connectors on the power supply side installed in situ First rack (200 cables/connectors) completed early in July –Work performed by SEDELEC (subcontract of KontaktSysteme that provides the double length cables - Many mistakes –~15 connectors have been repaired (mechanical) –Several label mismatch still to be fixed –~10 need serious repair (electrical) –They raised the cost significantly for future connector work New Plan –TC help with connector attachment –Nicolas Massol joined TC in September. One of his tasks is to organize connector activity –Work with Petr Kubik (Prague) to discuss technical aspects and qualify samples made by other companies being contacted –Meanwhile all cables are being cut to some extra length and ~ all tooling has been purchased to make prototypes –Qualification of one company (CPE/Italy) in progress –Work might start soon Plan for testing with cables plugged in PS crate Prague is going to design feedtrough board

9. 25 October 2005A.Ciocio - SCTSG9 Rack Scheme for PP3

10. 25 October 2005A.Ciocio - SCTSG10 Status of PP3 Cables are plugged in a few dummy Patch Panels during installation to be placed in the right (final) position and are tightened to horizontal bars Cables will have to be all removed from the current position and plugged in by groups/rows when the installation of the real PP3 will occur Big shipment of rack railing, PP3 housing crates, horizontal bars has been received (827 Kg) Ashley French currently at CERN has been dressing all the USA racks First 100 PP3 units are under preparation 60 units will arrive at CERN next week for burn-in and 40 will be burnt in at Melbourne The hold up so far has been the HV inserts Following a successful test, the company will be given the go-ahead for the remaining 4000 units. Expected production time is 2-3 weeks We’ll work on a scheme for shipment that agrees with the schedule Shaun Roe and Igor Ilyashenko with the help from Pamela Ferrari and Ewa Stanecka will set up testing and burn-in – Duration of tests to be decided Ashley F. and Scott Moncrieff should arrive at CERN on 14 November and will stay for four weeks Estimated installation of 200 units per day but more people will be needed to help on US side racks

11. 25 October 2005A.Ciocio - SCTSG11 Testing Tester designed and provided by Ljubljana (Gregor, Erik) –2 Test box + 2 Laptops + test cables –Need upgrade of test cables which are decaying after so much use –Lots of problems lately Test steps: –Cables are tested at reception (acceptance test) –After being pulled from UX15 to US(A)15 (uncut-double length) –After they are cut in the US side at connectors are installed Shift planner (developed by D. Robinson) works very well for planning the activities and have people to sign up http://www.hep.phy.cam.ac.uk/si-bin/sctworkplanner.cgi –(and contact me because of unexpected changing in rate delivery/testing problems) What is needed to be able to take a shift: 1)take the safety training course (at the pompiers station) 2)make the access request on EDH 3)get your safety boots & helmet (or borrow them)

13. 25 October 2005A.Ciocio - SCTSG13 Summary Installation on US side completed –Cables delivered and tested –Cables routed and tested –Cables cut to extra length Installation on USA side started –Delivery of double length harnesses restored –If rate of 150/w expected installation completion at the end of year unless interrupted by type ii/iii installation Connector work –Qualification of company in progress PP3 –First 100 unit will be at CERN soon (60 next week) –Remaining 4000 hopefully early in December –Installation of PP3 units 100 in November – then gradually in December Testing –Good presence of SCT collaborators – need to continue
