SCT Service Installation Overview Status of Type IV Cable Installation Type II/III Cable Installation Plan for the next six months Safety course today @ 12:45 A.Ciocio - ID Week
Overview • 2044 (+spares) double length Type IV cables (Power & Control) from PP3 racks through holes to US(A)15 racks • 4088 (+100 spares) Type II/III (spliced on the outside of the calorimeter and up at z=0) from PPB(F)1 to PP3 racks • DCS, Heater Cables, and PP3 (will be discussed in the ID installation) • 8 PP3 racks in each side of the cavern (US&USA sides) • Up to 10 crates of 30 PP3 units • 11 power racks in US15 and 11 in USA15 • Up to 4 crates of 48 channels • TC installation team: • S.Malyukov, E.Kudinov, L.Reed, N.Massol • 27 people from IHEP Protvino • Several teams are working in parallel (~9 people per team) A.Ciocio - ID Week
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 A.Ciocio - ID Week
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 A.Ciocio - ID Week

PP3 to US A.Ciocio - ID Week
PP3 US(A) side Power Supply UX side Installation of Type IV Cables Hole • Type IV cables are delivered in double lengths and pulled between the UX15 and the US(A) caverns • ~800 pieces (double length cables) installed on US side (almost completed) • Up to 40 cables per day pulled from UX to US(A) Dummy PP3 Racks on Level 6 US side A.Ciocio - ID Week
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 (~20 connectors have just been repaired) several label mismatch still to be fixed • They raised the cost significantly for future connector work • New Plan • TC will 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 cables are being cut to some extra length and ~ all tooling has been purchased to make prototypes A.Ciocio - ID Week
Delivery Issues • Installation rate driven by delivery schedule • Delivery in July/August was very slow • Vacation and QA problems • Connectors quality • Bobbins damage • Bobbins already at CERN are going to be sent back to the fabrication company (Novacavi) to get cleaned up • Delay of components delivery from CERN to company • Need to keep contact with CERN purchasing and Vendor • Ramp up • 200 pieces/week expected soon after bobbins damage crisis is solved but so far the max number of pieces we have seen is 120 • Hopefully all type-IV delivered by mid-November A.Ciocio - ID Week
Delivery (QA - Connectors) • Connector’s signal wires too long • Some cables couldn’t be used • One week halt of production A.Ciocio - ID Week
Delivery (QA - Packaging) • Packaging: palette were sent with only plastic wrap around bundles • Cables were getting wet during transportation and delivery at CERN • About 40 cables lost (~30 in one delivery) A.Ciocio - ID Week
Delivery (QA - Bobbins) • Cable bobbins dirty and damaged • Bobbins are kept outside (at CERN) for long time • Other (than water) damage under investigation • Company claims delay in fabrication to deal with these problems • Don’t know yet delay due to shipping bobbins back to Italy A.Ciocio - ID Week
Connector type II: JST SHDR-20V-S-B and FCI65239-002 Connector type III: CONEC 3017W5PBK99A1OX, 131C11019X, and 132J14019 Strip-Back Length A MPPBF1 (Type II) MPP2 (Type III) Splicing connection Foil Shield Strip-Back Length B Type II/III Cables • Double harness ordered from Ineo • Work on splicing started in August • Installation of connectors on the PP3 end at the factory • Need to provide exact length for both types • Use dummy PP1 with some load to test that the splice didn’t get damaged after installation • JST and FCI connectors very delicate – better to test at the PP3 end • Two Contracts first to produce all the harnesses and then to install the connectors • Splice is verified at the company • Need QA going on during production • Last visit by Pepe B. Maarit W. and Laurent Gillain(CERN purchasing) quite satisfactory • By November all harness will be made • Cables with PP3 connectors between November and March A.Ciocio - ID Week
Current Installation Activities (Type IV) • Overall coordination (Sandra) • Work closely with Sergei Malyukov and the TC team • Provide complete layout/mapping for racks in both sides • Bjarne is still helping from Bergen • Regular presence to check mapping/labels and prepare racks • Discussion on installation priority and occasional revise original layout • update DB table and EDMS documents* • Organize cable testing shifts • Connector at the power supply end (Petr Kubik/Prague) • Cable testing (Sandra, Petr and SCT Collaboration) • Follow up cable procurement and delivery (Pippa, Sandra, Maarit/TC) • PP3 installation soon (Ashley French/Melbourne with Petr) *SCT Cables EDMS ID:624679, Cable Procurement Follow up table ID:508310, Overall Safety and Health Procedure ID: 593278 A.Ciocio - ID Week
Type IV Testing • Tester designed and provided by Ljubljana (Gregor, Erik) • 2 Test box + 2 Laptops + test cables • Gregor and Erik upgraded features of tester in July • Web based DB • 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 • (register and contact me) • What is needed to be able to take a shift: • take the 3-levels safety training course (at the pompiers station) • make the access request on EDH (ATLAS-U, LHC Tunnel) • get your safety boots & helmet at the CERN store (or borrow them) A.Ciocio - ID Week
Procurement Schedule • Type IV delivered and installed December • Connector work of Type IV (power supply end) could start in 3 weeks and it will take ~4 months January • Type II/III double harness with splicing January single cable with PP3 connector Nov-March • PP3 delivery and installation Oct/Nov A.Ciocio - ID Week
Work Plan A.Ciocio - ID Week
Safety Training Course • Building 65-1-003 (Pompiers station) • At 12:45 • Please arrive 5 minutes earlier to register A.Ciocio - ID Week
