  1. SCT Services Installation Update • Recent Full Report: • September ID week • SCT Cables Web page: • http://www-atlas.lbl.gov/ciocio/SCTcables/ • Workpackage: • https://edms.cern.ch/document/593278/ • EDMS: • 624679 Specifications of SCT power cables, type II, III and IV • 783753 SCT Power Cables Layout A. Ciocio

  2. 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 • ------------------------- • 100% 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 A. Ciocio

  3. 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 1st • 70 % of cables are re-connected to PP3 A. Ciocio

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

  5. Type IV cables from Power Supplies racks in US15 Through wall holes About 30 meters Type II-III cables from Cryostat PP3 Racks - US side Sector 3 Sector 1 Sector 15 A. Ciocio

  6. 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 A. Ciocio

  7. 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 A. Ciocio

  8. 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 1st • 8 USA racks with Barrel cables completed last week • The last 3 racks (EC) by End-October A. Ciocio

  9. 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 A. Ciocio

  10. PS rackslayoutpriorities for connector in-situ and plug-in A. Ciocio

  11. 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) A. Ciocio

  12. SCT Readout Cable Installation • All 144 SCT Readout Cables installed and tested • See (September) ID week report • No update A. Ciocio

  13. Schedule(Power Cables & PP3) • Barrel • All Connector in situ (USA15) + testing end-October • PS crates (USA15) mid-October • Test of whole chain (sector 1, 3, 7, 9) end-October • sector 11, 15 mid-November • PP3 & cabling • PP3 rework (done) end-September • All cables re-plugged into PP3/PS end-October • Endcap • 3 USA15 PS racks installation November • 3 US15 PS racks installation January 07 • Test of whole chain November and January 07 A. Ciocio

  14. PEOPLE 2006 + Freiburg, MPI, Japan, Glasgow, Manchester, Lancaster, UCL, Oxford, Cambridge, Geneva… A. Ciocio

  15. 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 A. Ciocio
