Installation of Type IV Cables

• 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)

Racks on Level 6 US side

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

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

10
Delivery (QA - Connectors)

• Connectors signal wires too long
• Some cables couldnt be used
• One week halt of production

11
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)

12
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
• Dont know yet delay due to shipping bobbins back
  to Italy

13
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 didnt 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

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 ID508310,
• Overall Safety and Health Procedure ID 593278

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)

16
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
