Plan

1
Services Update

• Progress on services
• Detector cabling
• Gas systems
• Cooling systems
• Rack footprint
• Primary electrical distribution
• Utilities
• Principle Priorities
• For Q4 2003

2
Progress On Services

• Services on RB26 side
• Must be installed this year, in order to close
  the doors
• Complex routing limited space
• Temporary supports will be required inside the L3
  magnet

Layout at time of last ALICE week
Some gas cooling pipes
Basic Bus Bar layout
Some cables

Detector Cabling (1)

• Inventory well advanced
• Over 1600 cables to be installed on RB26 side

Rack allocation
Cable type CERN standard or special
Typical inventory for TPC

Detector Cabling (3)

• High voltage and signal cables
• Will be installed using the existing EST/LEA
  industrial support contract
• Under the direct supervision of the ALICE team
• Cables will be installed and cut to approximate
  length
• Cables will be cut to the exact length and
  connectors will be added, when the detectors have
  been put in place
• Fiber optic cables
• ALICE team will install the ducts
• The specialist team from ST/EL will blow the
  fibers at a later date

Rack Footprint (1)

• Standard 52U high racks
• UX25 cavern
• 133 racks have been identified
• Racks allocated to sub-detectors
• Numbering follows CERN ST/EL standard
• Grouped into 4 areas (see following slide)
• PX24 counting rooms
• Existing racks will be used
• Allocated as required

Rack Footprint (3)

• Crate allocation (UX25)
• Well advanced
• 60 out of 132 racks have detailed crate layout

16
Primary Electrical Distribution

• Now well understood
• Power for counting rooms supplied from surface
  transformer
• Power to Experimental Area
• One transformer will supply power to racks
• A separate transformer will supply power to
  equipment with pumps etc.
