Public documentation on the LHC is provided by CERN, links are provided below. We will concentrate here on "LHC as seen from P1"

LHC facts and figures

• LHC faq, the guide is part of the CERN press-kit, a classic for all guides and contains cost (p17) & key figures (p30). Consumption numbers (very frequent visitors question) are now provided by EN department flyers
• CERN Accelerator complex: the map was updated in 2016 to include new experiments.

HL-LHC

• FAQ for public: on the CERN and its neighbours website
• Official material: press backgrounder, project web site, public project schedule , social media #HiLumiLHC tag and  civil work FAQ
• Ground-breaking ceremony: a time capsule is placed in P1. See in the file attached a few photos of the excavation area [28.08.2018]

ATLAS specific stories, images and videos

• All ATLAS public web site updates tagged with LHC, Control room , Detector Operation
• Chapter 6 of the almost-ready ATLAS25 book tell the story of the cavern excavation and detector installation. 
• Responsibility sharing:  CERN is responsible for the LHC machine. Its contribution to experiments includes infrastructure costs, such as the caverns and facilities that visitors see @P1, plus and computing. For official nunbers see FAQ guide page 17.   

What do we see in P1 ? 

AVC: use the medium slideshow of the smartboard

LHC depth and tilt: official numbers are 1.24% and a depth of 175 m under the Jura, 50 m towards the lake. One usually quotes 70m for ATLAS. The LHC tilt can be seen by comparing the ATLAS supports and the platforms on which visitors are standing (see file attached). As explained in chapter 6.6 of the ATLAS25 book, it makes ATLAS endcap A opening (= airport side, "down hill") very different from C opening (= Charlie's pub side, "up hill").
