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.
