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 lastALICE week

Basic Bus Bar layout

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

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.
