Warm structure assembly
Most critical connection is 6 and 7
All bolted connections compliant with Eurocode 3
Using sand blasted surfaces to increase friction
co-efficient.
Will use strain gauges etc to corroborate FEA
calcs.

Gangways in BT

• The brackets for the access gangways in the BT
  coil will be installed where possible as the coil
  is assembled.
• After removing the BT coil jacks, and the barrel
  calorimeter put into position, the gangways and
  barrel muons will be installed as the BT assembly
  platforms are removed.
• Prototype platform received from Pakistan.

Barrel Calorimeter
25
Barrel calorimetry

• Activities on truck C
• Approx 50 of the Tile Calorimeter assembled.
• Installing now on the lower half all calorimeter
  cable trays, cooling pipes, cryostat
  supports, CS sources pipes, some cables.
• Lower the barrel cryostat on Oct 26th
• Complete the mechanical installation of the Tile
  Calorimeter
• Trial movement of Barrel Calorimeter (1 metre)
• Install on the upper half all possible calo
  services
• Install and then partially remove all ID cables
  supports on the calorimeter surface and front
  faces, including all possible pipes
• Install the LAr electronics racks and start the
  electronics cards installation and commissioning
• Commission the tiles drawers electronics
• Prepare all hardware to move the calorimeter
  inside
• Move barrel calorimeter into BT (August 2005)

Barrel Muon Chambers
32
Muon barrel 1st Phase installation Jan 2005

• First phase installation planned for muon
  chambers in feet region.
• Will consist of all BMF, 4 - BOF, 6 - BOG in
  sectors 12 and 14.
• Maybe some BML and BOL in sector 13 (depends on
  truck position).
• Feet region very complex detail design with small
  clearances between chambers and feet.
• Installation has to be quick as on critical path.
  
• Access is complicated over the large volume
  occupied by muon chambers.
• Will try and put as many brackets and rails in as
  building up the BT. But there will be final
  adjustment of brackets and rails after jacks
  removed from BT.
• Task force working on variations of installation
  sequence/methods to save time in schedule.

BMS Installation options (part of task force
study)
Using crane and during BT assembly. Saves time
but risk of damage
Using tooling from BML rail.

Services
39
Services

• As much as possible of the services that run
  along the barrel calorimeter surface to Z zero
  will be added while the calorimeter is on the
  truck.
• At present services are being installed on the
  lower half.
• When cryostat installed and top half of
  calorimeter completed then services installation
  will continue.
• Elsewhere services are being added-
• Calorimeter services from USA15 to HS.
• ID Type 4 services from HS to USA15 and US15
• Magnet bus-bar installation on HS and gallery to
  USA15
• Cryo lines to Zzero.
• Start equipping racks in USA15
• Start installing racks on HS.

Conclusions

• Between mid Oct and Xmas 2004 very critical
  period for the installation of Atlas.
• Installation of two BT coils.
• Lowering of Barrel cryostat and build up of
  calorimeter.
• Now know BT availability in more detail.
• Planning to complete the BT by July/August 2005.
• Install barrel calorimeter by end August 2005.
• Not having components (inc small items e.g.
  bolts) on time and in right place will cause many
  delays.
• As the toroid is assembled aiming for-
• early installation of services.
• early installation of muon chambers in the lower
  sector
• preparation for the ID cables installation.
