Effort for Installation and Testing

1
Effort for Installation and Testing

• Attempt to collect information from previous
  talks
• Web shift list has been established (Dave
  Robinson) http//www.hep.phy.cam.ac.uk/si-bin/sctw
  orkplanner.cgi
• Natural to extend this pool of ad-hoc SCT
  shifters to cover future installation testing
  where little training is needed
• Also need experts to coordinate (and sometimes
  do) work
• I will give very rough estimates of the numbers
  of shifts, scaling from Sandras needs for Type
  IV

Type IV cables

• Sandra Ciocio and Petr Kubik working full time
• Shift list seems to be working for testing
• Big problem to organise putting on connectors in
  situ.
• Try the solution of an external company proposed
  by Marzio Nessi.
• Do any SCT institutes have qualified technicians
  who could come to work at CERN for a few months
  to make connectors?
• Do we appeal to other ID institutes (eg. TRT
  institutes)
• Sandra estimates 600 shifts
• These are 3 hour shifts. Two people in a team, so
  600 shifts correspond to 150 days.

PP3

• Shaun Roe and Igor Ilyashenko will do testing at
  CERN, with help from Pamela Ferrari and Ewa
  Stanecka for setting up (CERN)
• Ashley French (Melbourne) coming on 1 October for
  installation (for how long?). Occasional help
  from SR1 technicians for mechanics, when Ashley
  isnt here.
• Igor will also be available to help with
  installation.
• Tests in situ will add a new task to the list of
  the cable testers.
• Remains to be seen how easily one PP3 card can be
  swapped, if there is a problem!
• Testing PP3 in rack 200 shifts

Type II/III cables, dPP1

• Need qualified technicians to install dPP1, and
  to supervise connector type II end.
• Sandra/Piotr should be able to supervise
  connecting/testing at PP3 racks.
• Will continue to need rotating shift crew for
  tests
• Still need to understand connection sequence and
  test procedure MUCH more delicate if we have to
  test double harness, just from PP1 end.
• Acceptance test (do we do it?) 100 shifts
• Tests after installation (if double harness)
  200 shifts
• Tests of cables from PS to dPP1 after connection
  at PP3 300 shifts

Power supplies

• Assume Jan Bohm, Jan Stastny and colleagues will
  provide staff, as before.
• No additional shifts needed to test power
  supplies
• Will also need detailed checks of mapping. DPP1
  are supposed to have an LED incorporated, so
  visual checks of what switches on can be made.
  This might use the ad-hoc shifters as
  assistants.DCS/PS system tests 100 shifts

6
DAQ/ROS, fibres

• John Hill listed the UK people available for
  installation and testing
• Fibre testing can not be done by ad-hoc shifters
  will need a few trained people (probably also
  from UK)

7
DCS

• See Pamelas talk
• Testing to be done by Richard Brenner, Pamela,
  Heidi
• Assume they need one ad-hoc shifter to assist
  an additional (3hour, 1person) 30 shifts

8
Cooling, heaters, HEX

• See Steve McMahons talk.
• Relying on the ad-hoc shifters for cable testing
  during installation. Total of 700 cables.
• Pixel institutes should also contribute here
• 100 testing shifts

9
Tally of testing shifts needed

• These are 3 hour, 1 person shifts. Usually they
  work in teams of two people, or assist an expert.
• They must have access to the pit training
  course to level 3, hard hat, safety shoes
• Shift list totals dont take into account the
  uneven load on institutes for more expert
  installation tasks

Type IV cables 600
PP3 tests 200
Type II/III cables and dPP1 600
Power Supply DCS system tests 100
DAQ/ROS (experts only) 0
DCS cables 30
Heater cables 100
Total (rough estimate) 1630
