## 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)

- Dummy PP3

- Racks on Level 6
- US side

- Hole

## 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

## Delivery (QA - Connectors)

- Connector’s signal wires too long
- Some cables couldn’t be used
- One week halt of production

- A.Ciocio - ID Week

- 27 September 2005

## 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

- 27 September 2005

## 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

## 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

## 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***

## 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](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)
