SCT Services Installation

• Type II-III and PP1

• Testing & Installation Plan

Workpackage https://edms.cern.ch/document/593278/SCT Cables Web page http://www-atlas.lbl.gov/ciocio/SCTcables/


Status of Type IV Cables• Cables production

– resumed in February after 3 months stop– See ID week February ‘06

• Delivery of doubles harnesses completed (April)– 2125 double harnesses (4250 cables)

• Installation– All racks in US side + 2 USA racks were installed last year by TC Russian teams – Installation resumed at the end of March with a new TC team (French) – Very slow startup, safety issues, wrong usage of labels, mistakes – Completion of USA side was expected by the end of May

• But <50% done– Russian teams will take over 1-2 racks – expected completion end of June – Need to test last ~200 cables for acceptance– Need to test after installation to be able to cut extra length to liberate floor in USA15

• Connector in situ (CPE)– All connectors (2000) in US15 completed on March 10 (a few were left but they are done

now)• Many racks are tested before and after plug into PS (Petr with Prague team)• Very good yield but some rework was necessary • One rack needs cables rerouting (cables were cut too long by previous company)

– 2+1 CPE techs returned on April 18, started 2 USA racks but left again:Need more USA15 rack completed for the full team to operate efficiently

– US side was reworked and connector in situ in USA15 will be continued when full team will be back (mid-June)

PP3• Remaining units and parts about to be finished and will be sent

“soon”

• Scott will come back (June 13) for 4-6 weeks

• Much of the installation done but lots of work to complete all racks:– Most of subracks of 30 units installed– Need 7 subracks to complete all installation and “special” subracks– Some subracks sitting by racks to be installed– Only a small fraction of cables are plugged in

• Issue with schedule:– Rework for damages, shorts, bad assembly had to happen when

needed but only occasional technical help was available– Problem of not having all the parts in hand, hence can’t complete racks

under installation right now (very bad!)


PP3Units sliding off


PP3 • Sealant silicone instead of silicone glue was used at some point• Only one spot instead of “5 spot” pattern

PP3


Type II/III & PP1 – Production• INEO/Thurmelec are making type II-III cables in 2 steps:

1. double length harnesses as they receive information about the lengthstype II cable and type III splicedtype II FCI/JST connectors on both ends of double harness

2. Single length cables with FCT connector (PP3) are produced when length finalized with test cable measurement from cryostat to PP3 racks sector by sector

• Delivery rate reached 300 cables/week• We are ahead with cable preparation!• So far good quality• No fatal defect found on some cables (the color coat is gone is some section/pattern

but kapton insulation OK)• Fatal defect (but repairable) found on 2-3 cables• Only a few cables failed acceptance

• PPB1 – clamps, clips, cable tray covers were late, not used yet during installation– Clamp mounting started– Clip under production

• PPF1 – most parts available– Found the best way to crimp group of drain wires in a ferrule and catch the ferrule with the

grub screws into clamp’s holes


Type II/III cables – Defects


Bad work during preparation!


Type II/III cables – Installation


Type II/III cables – Installation• ~ 2300 cables installed• ½ bundle /day/side/team 48 cables/day but may reach 100

Old problems:(Details given in April SCTSG)• Problem with testing related to the grounding in cryostat (OK)• Mechanical problems to fit layers of 6 cables between cover/clamp holder pins (all cables installed have been retrofit)• Clamp installation

Yield:• <1% cables to replace

- Mechanical defects- Damage during installation and preparation- Failed electrical test

SCT Services Sequence• Sector 5 (top) and Sector 13 (bottom)

– heater cables, and DCS cables (completed)

• Sector 9 - Installation completed on May 1– 878 SCT cables (384 Barrel, 494 EC)– 18 Fibre cables (EC)

• Sector 3 - Installation started May 2 – completed last week– 583 SCT cables (336 Barrel, 247 EC)– 27 Fibre cables (9 EC,18 Barrel)

• Sector 1 - started in parallel 2 weeks ago – will be completed this week– 878 SCT cables (384 Barrel, 494 EC)– 18 Fibre cables (Barrel)

• Sector 7 – first 300 cables arrived – installation in parallel just started– 583 SCT cables (336 Barrel, 247 EC)– 27 Fibre cables (9 EC,18 Barrel)

• Sectors 11, 15 – Double harnesses length sent to company to fabricate – single length this week– 583 + 583 SCT cables (336 Barrel, 247 EC)– 27 + 27 Fibre cables (9 EC,18 Barrel)

• Installation sequence in a sector is:– Tubes, fibres, heater cables, SCT cables, (Muon chambers), – TRT cables, pixel cables


Schedule• Type II-III installation should be completed by mid-July (according to current schedule from TC)

• Type II-III installation mid-July (Barrel)• Type IV installation end of June…(?)• Connector in situ+testing end of July…(?)• PS crates end-June (US side) – July-Aug (USA side)• PP3 assembly, installation end of June• All cables plugged into PP3 mid-July-August(type IV) for type II-III later

We need continuous presence of people at CERN at least until mid-July(and later in August)• Critical area in the type II-III acceptance, installation and testing• SCT participation very valuable to add to people who are resident

Plan


Issues• PP3

– Help is coming next week but continues to be difficult to keep up with technical problems and missing subracks

• Connector damage– In US15 they are left too long on the floor– Other cables installation interference

• Tester– Different flavor that work with different configuration of cable chain– Multiple laptops failure (~ok now)

• Spares installation for type II-III cables– We don’t have spares of every flavor – need rework to get the right one in place

• Defective dPPF1– Some faulty cables were actually due to a bad channel on dPPF1 – still missing some

dPPF1• Type III installation & testing

– Difficult conditions for testing– Extra length to reroute on additional trays– Dedicated team (Russian) available to plug-in but need assistance (and all cables tested)

• Type IV installation – Very inefficient and need extra interaction with new team– Interference with type II-III installation and blocking connector in situ work

• Connector in situ– With the current rate of type IV installation difficult to keep schedule as planned– The very first rack has 200 cables to reroute under the rack to absorb the extra length

• Need more (competent) HELP for the following weeks – Challenge to coordinate and supervise so many people changing every week (and every day)


To work on cabling • http://www.hep.phy.cam.ac.uk/si-bin/sctworkplanner.cgi

To sign up for shifts (and contact me because of unexpected changing in rate delivery/testing problems)• Safety courses:

1) basic safety training course (level 1-2-3 video in B55)http://safety-commission.web.cern.ch/safety-commission/SC-site/sc_pages/training/basic.html

2) Level 4 for working in US15 + Oxybox (we have them)If you have an AIS LOGIN (used for EDH documents), you can follow the course from anywhere (even outside CERN) with AIS login by accessing http://sir.cern.ch. If you have no AIS LOGIN, you need to register at the following address [email protected]

3) Level 4A mandatory to enter the ATLAS underground areasThis course is composed of 4 modules : Cryogeny, Evacuation, Installation and Magnet. Each of these modules is followed by a small test which you have to take and pass.

If you do not yet have an AIS login, please contact the ATLAS secretariat and ask for this AIS account (they must be registered with ATLAS). If this is not possible, we will organize special training at CERN.

4) make the access request on EDH5) get your safety boots & helmet (or borrow them)

TRY TO GET AS MUCH AS POSSIBLE DONE BEFORE COMING TO CERN…
