LHC Electrical Installations: Status Report

During 1999 the ST-EL group started detailed preparations for the electrical installations for the LHC. The areas of activity have been zone 18, access point 5 and the preparations around BA 4 and BA 7. Another activity performed during 1999 was the laying of the 18 kV cable link from LHC 6 to LHC 5, which will supply the CMS experiment. The intensified study work has, since the end of summer 1999, been effectively supported by an additional study office, staffed by contractor's personnel. Detailed studies and work require a clear definition of tasks. This has been developed within the EL-NP section and will be refined as the needs develop. The possibility of an ST-EL support for the cabling of the LHC experiments is currently being investigated. This is an additional field of activity, not earlier covered by the ST division. An important aspect of any status report is the budget follow-up. The very strict financial framework for the LHC project requires constant vigilance, even for the smaller budget volumes.
