Services and Patchpanels Installation

Services and Patchpanels Installation

• Type IV installation
• Connector in situ work
• Status of PP3
• Type II/III
• Testing

2
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(A)
  halls
• US side completed (October) 2044 cables
  spares
• USA side installation started more than a month
  ago
• Problematic Delivery
• 692 cables received so far
• Oct 20 (91 harnesses) 26 Oct (155 harnesses)
• Delivered as double harness but the total length
  corresponded to single cable length (mistake in
  the request)
• Installation of the harnesses as single cable
  (246) almost one rack on level 1 completed
• Test after installation between UX15 and USA15
  more complicated
• Connectors at PS side are cut and will be re-used
  by the company (part of it)
• Skipped one week because of delay on sending
  bobbins of raw cable from CERN
• Nov 16 (193 harnesses/386 cables)
• Length is right (100 m a piece)
• All 386 cables (tested) are on hold for
  installation since TileCal cables are being
  installed and TC team is reduced
• but we are in line for installation
• Dec 9 (only 44 harnesses/88 cables) after a long
  period
• No large delivery of new cables due to a weird
  technical problem at the factory
• Expected complete delivery of harnesses in
  January
• Installation of type IV is on hold for the rest
  of the year and later on it might be interrupted
  by type ii/iii

Connectors in situ

• Double harnesses will be ultimately cut to
  length (1 meter extra for now) on
• the PS end and connectors will be installed in
  situ by an external company
• Tooling has been purchased to make prototypes
  and understand issues
• of this construction
• All cables in US15 have been cut to extra length
  and are ready to be
• worked on
• First rack (200 cables/connectors) completed
  early in July
• Work performed by SEDELEC, subcontract of
  KontaktSysteme,
• that provides the double length cables
• Many mistakes
• All cables are fixed now (Petr)
• New Plan
• Marzio helped finding a company to do the work
• Nicolas Massol (TC) contact with companies
• Worked with Petr Kubik (Prague) to discuss
  technical aspects and qualify samples
• CPE(Italy) selected and contract has been signed
  3 weeks ago
• Several meetings including a one full day at CERN
  with CPE senior engineers and
• phone conversations to improve their methods and
  define all the issues

Status of PP3

• PP3 units are in production!
• First 100 units were received in October
• 600 production units arrived 2 weeks ago 400
  just arrived
• Testing
• Shaun Roe (initially with Igor Ilyashenko and
  help from Pamela Ferrari and Ewa Stanecka for the
  setup) carries on the testing and burn-in.
• 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)
• Didier Ferrere has also tested one PP3 with a
  module, again simulating the situation where the
  module loses the clock and draws no current,
  while observing Vdd and Vcc with an oscilloscope.
  
• He reports no voltage spike observed.
• Plan to test the entire chain (modules/final
  cables/PP3/PS) in SR1
• 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
• Ashley French and Scott Moncrieff (Melbourne)
  worked on assembly and installation
• Estimated installation of 90 units per day
  (limited today by testing capability and
  problems)
• 4 PP3 crate have been installed so far
• 15 crates assembled (6 ready to be installed)
• Problems

6
Type II/III

• TC management Nicolas Massol, Siggi Wenig and
  team
• Checks with INEO (St Genis)/Thurmelec (Alsace)
• Pippa/Sandra/Pepe Bernabeu/Maarit White (prepare
  tables of lengths, QA of qualification samples
  etc.)
• Martin Postranecky (will probably be checking
  samples of double harnesses at CERN
  organization to be finalized)
• Installation of dummy PP1 and type II cables
• Lars Erik Lindquist (Uppsala) Neil Fletcher
  (Liverpool) new technicians (will also get
  familiar with detector in SR1)
• Andy Nichols, Janet Fraser, Jason Tarrant,
  Patrick Werneke to advise on installation/labeling
  of first examples
• Routine tests after installation
• Sandra/Petr Kubik and shift crews
• Will install PP3s in racks to which type III
  cables arrive with highest priority
• PPB1 need cable tray covers
• PPF1 rather more parts needed. Cable clamp
  redesign by NIKHEF. Other parts on order via RAL.

Timescale for Type II Services

• Calorimeter has moved to z0. Access to the
  cryostat is possible
• ID requests should be via Nicolas Massol.
• Sector 5 (top) first before end of the year
  (heater cables, and a few DCS cables)
• Sector 13 (bottom) may also start before end of
  year
• Sector 3 was supposed to follow sector 5, but
  is held up by problems with arches above detector
  and muon chamber installation
• Sector 9 horizontal towards USA15 may be the
  first to be installed with SCT fibres and SCT
  power cables. This sector is complicated by the
  flexible chains.
• Sequence in a sector is
• Tubes, fibres, heater cables, SCT cables, (Muon
  chambers),
• TRT cables, pixel cables

Plan for Type II/III cables

• INEO/Thurmelec are at present making double
  length harnesses with type II cable and type II
  connectors on both ends.
• Work is proceeding to schedule
• Problems with raw cable quality so far minor
  compared to type IV
• Will need to order about 4km more type II (sector
  9 longer) and 10-20km more type III (cables
  generally longer than expected)
• First 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 (could be up to 7mm with the initial
  definition).
• Samples of the FCT (type III) connector have been
  qualified
• Need cable trays to be in place to measure
  lengths of type II/III harnesses with trial
  cables before FCT cables are trimmed and FCT
  mounted on type III ends
• Company will then take 2-3 weeks to do this type
  III work
• Labels are defined and have been printed for
  sector 3
• Mapping is defined
• First barrel dPP1 are at CERN and have been
  verified with production cables and the Ljubljana
  test box
• Experts must verify that mapping is transferred
  to the cryostat bore

Testing

• Tester designed and provided by Ljubljana
  (Gregor, Erik)
• 3 Test boxes 2 Laptops test cables
• Need more test cables which are breaking after
  so much use
• Lots of problems during the last months but seem
  solved now
• Test steps (for Type IV)
• Cables are tested at reception (acceptance test)
• After being routed from UX15 to US(A)15
  (uncut-double length)
• After connectors are installed
• Test steps (for Type II/III)
• Cables are tested at reception (only samples of
  delivered batches)
• After installation row by row in the cable tray
• 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
• (and contact me because of unexpected changing in
  rate delivery/testing problems)
• What is needed to be able to take a shift
• take the safety training course (level 1-2-3
  video in B55)
• 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 level4.training_at_cern.ch
• make the access request on EDH

Current Shift Counts

• shift hoped to be fulfilled based on core
  participation but adjusted for agreed shifts,
  difference between pro-rata and agreed shifts,
  and cable funding participation - shifts from
  "difference" re-distributed between AUS (1/3)
  Cern(1/3) and countries that had not already
  agreed participation (1/3 equally divided among 5
  countries 0.066)
