Layout information :

Vacuum Layout     http://layout.web.cern.ch/layout/  under the multiple choice “Reports” select “LHC Vacuum Layout “, make your region choice and click on “Generate”. It takes some time to display the layout. There you can find the description of each component and its position respect to the IP.

Machine Installation Plan, the link is  here,  go to “Plans Installation machine” and you can select the sector you need. There all plans are listed (you can open them with the HPGLview)
