Disk?cylinder tooling

• Shielding foil added to cylinder
• Thermal feedthrough prepared
• Cylinder and stub wings assembled onto tooling
• 4 disk alignment tools being made by Manchester?
  delivered to Liverpool
• Disk grabber-design by Nikhef-manufactured by
  Sheffield/Lancaster tested with a diskCCDs and
  lighting now added and tested
• Disk fixations from Nikhef and Liverpool-delivered
  
• alignmenttarget holders designed (Nikhef) and
  manufactured (Lancaster)z-alignment tool needs
  to be finished

• Still to do..
• Qualify disk-grabber and disk alignment
• How to mount and de-mount the central beam
• concept ready, need to test

6
Cylinder?tooling

• Pre-aligment of rear stub wing mounting point
• Rear stub wing mounted onto frame
• Cylinder placed over beam and left on table with
  foam supports
• Cylinder bolted to rear stub-wing
• front wing offered up using sling for support and
  mounted
• Disk placed on disk grabber and cylinder aligned
• Disk moved through cylinder
• Very useful exercise! - lots of details to be
  sorted/have been sorted

Disk?cylinder insertion

• Capture and align a disk
• need to consider disk masses

Service status

• LMTsTesting of UK tapes at GlasgowPreparation
  of LMTs before assembly into trays?JT
• TIsWill be tested as part of LMT-TI harness at
  GlasgowFirst 100 delivered, full order soon
• String test LV/HV?test cable?TPPC?TI?LMT?PPF0?wi
  ggly tape?hybrid/module at Liverpool
• FibresLancaster has volunteered to take on
  reception testingFibres for disk testing (D1D2)
  at Liverpool, D9 at the end of Aug (?)
• Cooling pipesNow too late to assemble cooling on
  cylinder at Liverpool, now retro-fitted at CERN
  ?Assume no cooling pipes initially and connect
  direct to disk as for disk testing, then connect
  at STFT if pipes are delivered

11
TPPC string test (J.VoosebeldP.Dervan)

• String test
• Test cable ?TPPC?TI?LMT harness?PPF0?wiggly tape
  ?hybrid

TPP-C String-test on single channel test board
complete TPP-C ordered, string test on 32
channel pre prod board (1ch only) completetry
and do 2ch test ? (need additional LMT)
12
Service handling

• Thermal plug ordered and being manufactured in
  Sheffield (caravans!)
• PPF1 trays for LMTs in production
• PPF1 tray holdersorder placed last week-being
  modified
• temporary PPF1 for fibresLancaster have
  volunteered to make this, awaiting design from
  NikhefAt Liverpool we need to ensure we can
  connect in the coldroom
• Cooling-replicate disk testing system and connect
  direct to the disk-or similar
• re-evaluate when cooling pipes/connects start to
  be available

13
Test cable installation

• Test Cables for endcap testing installation
  startedRay Thompson, Andy Elvin, Richard French
• Basic mapping ready

14
Thermal plug
15
Status, going forward

• Assembly tooling is ready needs to be tested
• cylinder mounted and disk moved through on the
  beam
• Still to do
• test run of disk alignment, capture and
  removaldone but need disk masses
• Z-alignment tool
• Removal and insertion of the beam
• interface to disk holder
• floor, bracing and wheels, move in and out of
  cold room
• scaffolding for working on the cylinder

16
Status, going forward

• Service handling is progressing
• thermal plug being assembled
• LMT trays and tray holders in production
• Still to do
• DCS to be investigated
• Fibre holder design to be finalised
• Cooling, connect direct to disks at Liverpool,
  otherwise interfaces must be defined now to allow
  disk insertiontesting to go forward? assume HEX
  that we connect to disks/pipes at STFT so no
  longer need cooling pipes in service
  handling-how to make connections in the cold
  room-design manifold?? replicate disk test
  system and connect to disks
• Need services (LMTsFibres) to start developing
  methods for putting services on
• what tooling is required
• how to make test-fibre connections !

17
Status, going forward

• Developing tests for disk?cylinder assembly
• test cooling on disk with services
• during assembly to check connectionseg LMTs,
  check thermistors on modules
• Similar tests to those made on populated disks

18
DAQ/DCS

• PSU system
• 2 Artysyn power packs / shelves received
  installed.
• Original batch of LV/HV cards installed.
• Dummy load fabricated to allow testing of each
  channel. Testing of 6 channels completed.
• Readout and display disk thermal sensors
• DAQ
• 2 Rev E RODs installed.
• 5 hybrids 1 module mounted on disk 9 in cold
  room for multi-module readout tests (NB.
  Convective cooling to 0C room only).

19
Cooling plant

• Cooling Plant
• Manifold re-located to cold room, re-connected
  tested with 3kW load OK.
• Interlock using DCS from cooling pipes being
  developed
