1. 14 February 2006A.Ciocio - ID Week1 SCT Services Procurement & Installation Type IV PP3 Type II-III and PP1 Fibres Heaters DCS Testing MTF Workpackage https://edms.cern.ch/document/593278/

2. 14 February 2006A.Ciocio - ID Week2 Status of Type IV Installation Type IV cables are delivered in double lengths with connectors installed at the PP3 end and pulled between the UX15 cavern and the US/USA halls TC installation team: S.Malyukov, E.Kudinov, teams from IHEP Protvino UX side US(A ) side PP3Power Supply Racks on Level 6 US side - Length between 15-30.5 m (61 m the longest double harnesses) - Delivery and installation of 2044 cables + spares over the summer - Lower delivery rate than expected due to a series of problems (rain, drums damage, etc.) Installation between racks completed last October USA side - Length between 47-75 m (150 m for the longest double harnesses) - 720 cables received between Oct-Dec - Very low priority for installation of type IV since October - only half of the cables are installed - Connector problem resulted in erratic delivery for 2 months until production officially stopped

3. 14 February 2006A.Ciocio - ID Week3 Type IV Connector Problem The insulation can split when the conductor is bent in a small radius. Some strands are poorly aligned, and the insulation has thin places.

4. 14 February 2006A.Ciocio - ID Week4 Type IV Connector (cont’d) Meeting with cable producers (Novacavi), harness producers (KontaktSysteme), Laurent Gillain (CERN purchasing), Pippa and myself to discuss solutions to resume production (January 11) Options: Replace 100 Km cable already made - Novacavi can’t figure out how to improve their production - Delay of 2 months Use a bigger hood for less bending - Modify PP3 - Delay Use shrink tube over or replace the insulation with shrink tube - New cost estimate

5. 14 February 2006A.Ciocio - ID Week5 Type IV Connector (cont’d) First sample produced in January using the solution of stripping the insulation from the four power cables (8cm) and replace it with heat shrink tube 1 34 2

6. 14 February 2006A.Ciocio - ID Week6 Type IV Production –Previous pictures show a good sample but the insulation of the HV cable and the fat power cables were squashed inside the strain relief clamp –Final sample produced more carefully 2 weeks ago significantly improved – OK for production Production of type IV is still on hold awaiting a financial resolution Installation of type IV might be even interrupted when type ii/iii installation starts Still undefined schedule for completion of all racks

7. 14 February 2006A.Ciocio - ID Week7 Type IV Connectors in Situ All double harnesses installed in US15 racks are cut on the PS end and connectors are installed in situ by an external company CPE(Italy) was selected to do the job A team of 10 came in December. –The work started 2 weeks before XMAS mostly to understand how to cut to length, make more samples, plan the big job. –6 people came back on January 9 Technical appendix in EDMS https://edms.cern.ch/document/624679/1https://edms.cern.ch/document/624679/1 Workpackage https://edms.cern.ch/document/593278/https://edms.cern.ch/document/593278/

8. 14 February 2006A.Ciocio - ID Week8 Type IV Connectors in Situ Cables are cut to length using a dummy crate with PS channel mask plate 2 cm contingency

9. 14 February 2006A.Ciocio - ID Week9 Type IV Connectors in Situ Add shrink tube on power wires because of unlikely but possible insulation problem also on this side

10. 14 February 2006A.Ciocio - ID Week10 Type IV Connectors in Situ –First rack fully assembled on January 20 –Test of plug in PS backplane – OK –Electrical test – a few connectors needed rework –3 racks are worked on in parallel –Goal: 2 racks/week completed (realistically 1.5) As of Feb 10: 4 racks completed 2 in progress

11. 14 February 2006A.Ciocio - ID Week11 PP3 PP3 units are produced in Melbourne and shipped to CERN –First 100 units were received in October –~1000 by December and several subracks of 30 units were assembled –Currently: 1759 PP3s fully tested and 55 subracks assembled People: Shaun Roe coordinates the testing and burn-in of single PP3 units with SCT participation Ashley French and Scott Moncrieff (Melbourne) worked on assembly and installation in November/December Edward Gornicki (Cracow/CERN) worked 2 weeks on this in February Vladimir Golovkin (Protvino) at CERN for 1 month (until February 23) Scott M. will be back this week We need at least one technical person dedicated to this part

12. 14 February 2006A.Ciocio - ID Week12 PP3 Testing Single unit test 60 units can be tested at the time (2 PP3 crates) with the current number of test cables available - 40 more cables are under construction 24 hours with monitoring continuity on all lines, while varying the dummy load so that the Vcc and Vdd currents go to zero and the full power supply voltage is seen on the PP3. Voltage limiter test by applying 6V to each PP3 in turn (manually) PP3 related test: Currently the entire chain (modules/DPPB1/TypeII/TypeIII/PP3/TypeIV/PS) in SR1 - to measure how the shield works and noise generated at the PS - test OK - very low EM radiation of cables - report of G.Blanchot http://www-atlas.lbl.gov/ciocio/SCTcables/SCT_Power_Supplies_Conducted_Emissions_Report.pdf

13. 14 February 2006A.Ciocio - ID Week13 PP3 Assembly Mechanical Problems The plastic support feet of the PCB inside the metal casing of the PP3 had been broken in some cases and the PCB was therefore moving at one end - Replaced the broken ones - Requires careful visual inspection Subracks are checked for shorts Ground contact found between magnetic shields and/or strap holder due to the screw heads protruding above the surface - Kapton tape strips to cover screw-heads Ground contact found in the corner where units are very tight and insulation film gets damaged during assembly or when applying extra stress during installation in the rack - Extra kapton (or insulation film) inside the clamp 30 PP3 units are assembled in one subrack Insulating film applied on individual shield case A few drops of silicone to hold them together External clamp for rack mounting

14. 14 February 2006A.Ciocio - ID Week14 PP3 Installation & Plan Installation –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 –30 PP3 subracks (3 racks) have been installed so far Current Plan –Estimated installation of 90 units per day limited today by testing capability and problems –But also need the rest of PP3 units soon to complete assembly and installation –Need 200 special PP3s soon to go in the first rack where bigger connector hood were used - requires more tolerance (shorter standoffs) –Rework of remaining subracks (10) that don’t have kapton tape on screws either by taking the subrack apart – but difficult at times and risk of damaging insulation or replacing shield case –Rework subracks that need extra insulation on the corner unit –Installation of PP3s in racks to which type III cables arrive with highest priority –Need continue SCT participation to meet schedule and long term presence of at least one technical staff

15. 14 February 2006A.Ciocio - ID Week15 PP3 Installation

16. 14 February 2006A.Ciocio - ID Week16 Type II Services Timescale Since calorimeter moved to z=0 (November) access to the cryostat is possible –ID requests should be via Nicolas Massol Sector 5 (top) and Sector 13 (bottom) –heater cables, and DCS cables –Just finished Sector 9 horizontal towards USA15 to be installed next –SCT fibres and SCT power cables (886 cables + spares) –Barrel cables (side A and C) tried last week –a small number of fibres (end cap) should be tried this week Sector 3 –was supposed to follow sector 5, but was held up by problems with arches above detector and muon chamber installation –It’s going to follow Sector 9 Sequence in a sector is: –Tubes, fibres, heater cables, SCT cables, (Muon chambers), –TRT cables, pixel cables

18. 14 February 2006A.Ciocio - ID Week18 Type II/III and PP1 Production of double length harnesses of Type II/III spliced with FCI/JST connectors (PP1) and then single length cable with FCT connector (PP3) –INEO/St Genis -> Thurmelec/Alsace Prepare tables of lengths, mapping, labels, QA of qualification samples –Pippa/Sandra/Pepe Bernabeu/Maarit White Testing samples of double harnesses at CERN –Martin Postranecky/Pepe Bernabeu TC management –Nicolas Massol, Sigi Wenig and teams (Russians, Czechs) Installation of dummy PP1 and Type II cables –Lars Lindquist (Uppsala) & Neil Fletcher (Liverpool) – new technicians are getting familiar with detector in SR1 Lars is installing DCS cables –Andy Nichols, Janet Fraser, Jason Tarrant, Patrick Werneke to advise on installation/labeling of first examples Routine tests after installation –Sandra/Petr and shift crews

19. 14 February 2006A.Ciocio - ID Week19 Type II/III & PP1 - Status INEO/Thurmelec are at present making double length harnesses with type II cable and type III spliced, and type II connectors on both ends. –Work is proceeding to schedule (we are late) –Problems with raw cable quality so far – minor –We needed to order about 4km more type II (sector 9 longer) and 10- 20km more type III (cables generally longer than expected) –Barrel cables (sector 3) will have the type II ends remade to reduce the tolerance on the strip back length to the JST/FCI connectors to 2mm Samples of the FCT (type III) connector qualified (November) 44 double harnesses of the first production batch have been tested First barrel dPP1 are at CERN and have been verified with production cables and the Ljubljana test box PPB1 – need small clamps, cable tray covers etc. (March) PPF1 – more parts needed. Cable clamp redesigned by NIKHEF. Other parts on order via RAL. We just received a box with parts. Patrick will try to put them together then we can run test cable Will install PP3s in racks to which type III cables arrive with highest priority First cables with connectors at both end are currently being produced

20. 14 February 2006A.Ciocio - ID Week20 Type II/III cables – Installation Trial with test cable: Almost all cable trays are in place and we could measured lengths of type II/III harnesses with trial cables before cables are trimmed and FCT connectors mounted on type III ends (leaving 1.5-2 m extra length) http://www-atlas.lbl.gov/ciocio/SCTcables/TypeII-III/installation_test_cable/http://www-atlas.lbl.gov/ciocio/SCTcables/TypeII-III/installation_test_cable Found extra (more than extra) length to trim off – new lengths sent to the company –Labels are defined and have been printed and sent to company for sector 9 which is next –Mapping is defined – drawings for installation are made –Mapping for PP1 is in progress and will be transferred to Nicolas/Sigi For installation of sector 9: 100 cables will be ready on Feb16 + 1 week for Swiss Customs Issues to pay attention to: Grounding –The Type II cable does not have well defined potentials before inserting into PP1 therefore recommended using a shorting plug on the cable connectors before inserting into real PP1 ESD DPP1 connectors –DPP1 are used to test cables before installation (mechanical and electrical tests) –Many use cycles on the very thin gold plating could create a surface that is too abrasive for the delicate JST –Use and adapter or use a DPP1 as a test fixture only 20 times, then swap

36. 14 February 2006A.Ciocio - ID Week36 SCT Readout Cable Installation SCT Readout Cables go from PPB1 and PPF1 to the SCT racks in USA 15. PP1LF From Kamil Sedlak

37. 14 February 2006A.Ciocio - ID Week37 SCT Readout Cables and FSI SCT readout cables: 144 cables (+2 redundant) stored in 188-1-001. Each cable houses 6 or 8 ribbons with 12 optical fibres. MT connectors are attached to the ribbons on both ends. The ends (last ~1 meter) of the cables are stripped off, bare ribbons are protected by “light duty rigging” at the ROD end, and by “plastic bubble sheet” at the PPB1/PPF1 end. The cables will be pulled from the detector site towards USA 15. Light duty rigging protecting the bare ribbons. A chain is attached for convenient cable installation. FSI Delivery Cables: 38 cables with 6 or 7 ribbons, 8 fibres in each ribbon. Cables are not cut to the correct lengths, they are stored in two big drums (350 and 250 kg) in building 192-S-008 Cables go from rack Y.4-11A2 to the FSI splice boxes SB1-4 located on the cryostat.

38. 14 February 2006A.Ciocio - ID Week38 Ribbons connected to PPB1 done by Janet Fraser at UCL

39. 14 February 2006A.Ciocio - ID Week39 SCT Readout Cables - Status All 144+2 cables for the SCT readout and 2 long cables which will cut to 38 FSI laser light delivery cables are at CERN 18 readout cables (9 side A and 9 side C) will be installed in sector 9 FSI drums are moved to point 1 and cables installed directly off the drums –Immediately after installing the cable, we plan to strip it off at the splice box end to be able to pull the cable in case of fibre damage. –Fibres will be spooled in the splice boxes. They will be spliced together with the on-detector fibres once the ID is installed. Issues: Fibre position reference points (e.g. parts of the final patch panel, well defined position on the cryostat...) and the ribbon lengths from these reference points are almost clarified now. How to protect the bare ribbons in the time when other services are being installed is under discussion (ribbons for the end-cap might be protected by a garden hose, ribbons for the barrel by a temporary cover being developed by Andy Nichols). Stripping of the outer cladding of the cables needs to be done (at least for the barrel modules at PPB1 end). Delicate operation, as ribbons have been damaged during one of the stripping tests performed at UCL.

40. 14 February 2006A.Ciocio - ID Week40 SCT Fibre Cable Testing No acceptance test will be done before the cable installation to avoid spoiling the heavy duty rigging (Cables tested by Fujikura). After the cable installation, two test will be done: –Test of fibre attenuation: Check that the attenuation loss in the fibre and the MT connectors are within spec (all ribbons in the cables will be checked). –TOF for all TTC fibres in cables: Measurement of the ribbon lengths. Useful for setting up correct timing for Cosmics and the first data. –Both attenuation and TOF test systems (described at http://agenda.cern.ch/askArchive.php?base=agenda&categ=a05 5165&id=a055165s0t70/transparencies ) have already been tested at CERN. http://agenda.cern.ch/askArchive.php?base=agenda&categ=a05 5165&id=a055165s0t70/transparencies
