SCTSG - 17 October 2006 A. Ciocio2 Type II/III cables status 4088 cables: installation and testing completed ! 2112 barrel cables & 1976 Endcap cables 3594 cables (including all the 2112 Barrel) installed between March-July 494 (EC sector 11&15) installed in September % of the type III cables fixed on cable trays and positioned in PP3 (by TC) One recent faulty cable replaced (last week) Additional inspection, final verification and repair of damaged wires  ongoing Re-position (and insulation) of EC bundles and clamp on the flange  ongoing Test of the whole chain from Cryostat to Power Supply  ongoing Test of connectivity with Peter Phillips  November

SCTSG - 17 October 2006 A. Ciocio3 PP3 Rework Completed Because of insulation problem (see previous reports) ALL PP3 subracks of 30 units were: –disassembled –cleaned –glued properly –plastic layers (0.25 mm polyethylene terephthalate) inserted between all sides of PP3 units Disconnection of all cables was completed at the end of August (by the SCT cabling/testing team) –8000+ cables were hanging by the racks for several days –~4000 PP3 units in B161 Scott Moncrieff and Ashley French were at CERN for 4 weeks in September to do this rework –Many SCT collaborators participated in the re-assembling (THANKS!) –The last couple of weeks of September were very intense due to the late arrival of parts from Australia and running out of glue All PP3 subracks back in the pit and all re-installed by October 1 st 70 % of cables are re-connected to PP3

SCTSG - 17 October 2006 A. Ciocio4 PP3 Racks - USA side Sector 7 Type IV cables from Power Supplies racks in USA15 Type II-III cables from Cryostat Sector 9 Through corridors About 70 meters Sector 11

SCTSG - 17 October 2006 A. Ciocio6 Plan for PP3 Racks Rework Cables Reconnection & Testing (as of September 23) Taking into account: Connector in situ work PS installation Time to reconnect Time to test whole chain

SCTSG - 17 October 2006 A. Ciocio7 Type IV Cables Installation US side: –Type IV cables (2044+spares) from PP3 racks in the ATLAS cavern to PS racks in US15 Installed in 2005 (as double harness) Connectors in situ (March 06) 9 PS racks (8 for barrel) installed and cables plugged into PS backplanes (July) All type IV and type III (except for sector 15 EC) were connected to PP3 and test of whole chain done (in August) but then disconnected for PP3 rework USA side: –Type IV from PP3 to USA15 installation completed (end of July) –All type IV were connected to PP3 (17 racks in UX15) but then disconnected for PP3 rework –extra spare cables just added in several racks (USA side) All cables tested before and after installation

SCTSG - 17 October 2006 A. Ciocio8 Type IV Cables – cont’d Connector in situ (CPE) –All connectors (2100+) in US15 completed in March –“saga” to resume work in USA15  finally it started on Aug 1 st –8 USA racks with Barrel cables completed last week –The last 3 racks (EC) by End-October

SCTSG - 17 October 2006 A. Ciocio9 Type IV Cables – cont’d PS installation in USA15 (see next talk) –started 4 weeks ago –first plug-in/testing started on Sept 25 Testing –2 test systems are used for testing connector work and 2 test systems for PS/whole chain –1 test system failed 2 weeks ago  repaired after one week –Cables are first tested after connector work (plugged in PP3 – or not) to check connectors (rack by rack) –All cables are tested (whole chain) as they are plugged in row by row during PS connection –Test of whole chain in USA15 75% done now (sector 7, 9, 11) –Test of whole chain was performed on the US side (80 %) in end- July/August (but needs to be redone after PP3 rework) –Test of whole chain (again) in US15 started this week (sector 1, 3, 15) Test of sector 1, 3, 7, 9 will be completed in 2 weeks and partially sector 11 and 15

SCTSG - 17 October 2006 A. Ciocio11 SCT DCS Cables Richard Brenner + Lars Lindquist 128 type II and 40 type IV + 4 canbus Almost all cables between cavern and USA15 are installed Interlock cables in US15 installed Interlock cables between PS racks in USA15 and DCS rack in USA15 installed (4 cables x 11 racks) In the next few days we’ll resolve the rest of the cables to be installed: –Y34-23.X0 : 6+6 type II cables missing for Barrel but they have been routed from the cryostat to Z=0 –Y29-01.X1: 6+6 type II cables missing for Barrel but they have been routed from the cryostat to Z=0 –type IV interlock cables have been routed to Y04-05.S2 in US15, but unfortunately incorrectly –Y35-05.X8 : All type II cables are missing from the rack. The cables were left to the cable tray 2 m below the rack (Sergei told me that they have already started to route them)

SCTSG - 17 October 2006 A. Ciocio15 Final Remarks PP3 rework has added extra load to an already dense schedule of activities –The help received in the last few weeks has been crucial to make progress 2 days per week (over the last 3 weeks) of 2 techs (Jean and Gilbert) from Geneva Tony W. + Ellie D. Janet, Stephen H., Richard B. Nobu + Reisaburo Last week 2 techs (Andy and Mike) from Manchester This week 3 techs (Ines, Dieter, Patrick) from Freiburg Next week 2 techs (Joe B. and Richard S.) from Oxford October 30 (for 2 weeks) 3 students from Bergen Need additional technical people (two) from October 30 until mid-November Consequences of PP3 rework and delay of connector in situ work added difficulties to keep up with the schedule –We are falling behind schedule with reconnecting to PP3 and testing of the whole chain (also due to the test system failure) –We are one week behind with connection to PS –USA15 was very crowed and hectic in the last 3 weeks Hoping to catch up in the next 2 weeks and be ready for the final connectivity test with Peter Phillips
