Jean-Pierre Corso - CERN / 11.06.2014#OutlineLHC Tunnel : Slope, TiltVisualization Convention (reference axes)3D model position in spaceDCUMTypical SectionsModels CAD formatsJean-Pierre Corso - CERN / 11.06.2014#LHC Tunnel : Slope, TiltThe LHC is using the tunnel excavated for the LEP in 1985.This tunnel is NOT horizontal !The machine is like a circle turned by 1,4%~120m1,4 %Jean-Pierre Corso - CERN / 11.06.2014#The LHC from the space

~445m sealevel~330m sealevelJean-Pierre Corso - CERN / 11.06.2014#LHC Tunnel : Slope, TiltThe tunnel Section stays strictly horizontal everywhere along the 27km,and magnets are positioned in the plane created by the circle, each element of the machine will have at a certain point its own slope and its own tilt

A.KosmickiJean-Pierre Corso - CERN / 11.06.2014#Visualization ConventionEverywhere along the 27km, if you look at the LHC machine, you might consider following postulates:You lookfrom Ring CenterAbove the machineThe reference is the medium beam axisXaxis towards Ring CenterYaxis towards Beam downstream(*)Zaxis upward

(*) or following DCUM increase, i.e. on the rightA section of the tunnel is always shown from left looking downstream

Jean-Pierre Corso - CERN / 11.06.2014#3D model position in spaceThe reference of the model(0,0,0) located on the Beam Axis, start plane upstreamThe referential axis like this:Xaxis towards youYaxis towards Beam downstreamZaxis upwardLike this, each model can be handled by all technical offices with the same referential.

To be integrated properly, every element must be provided to our designers positioned within this rule:XYZJean-Pierre Corso - CERN / 11.06.2014#

IP1DCUM / IP1(9688 m)Point examplei know the DCUM:Where am i ???Jean-Pierre Corso - CERN / 11.06.2014#Typical SectionsThe LHC is composed of 2 main type of tunnels :Long Straight Sections [LSS] (~4km)Arcs (~23km)Jean-Pierre Corso - CERN / 11.06.2014#Typical SectionsArcs can be summarized with ONLY THIS:

Jean-Pierre Corso - CERN / 11.06.2014#Typical SectionsLong Straight Sections need more particular Sections

and 3D !

Jean-Pierre Corso - CERN / 11.06.2014#Typical SectionsSome portions of the tunnel are already reserved for dedicated Services, as Transport or SurveyQRL has its own area behind the machinePipes and cables stand behind the machine, over the QRLSafety equipements are on the wall close to passageAnd the concrete is foreseen not to move

Jean-Pierre Corso - CERN / 11.06.2014#CAD Models FormatsCERN designers use CATIA V5 (DS)STEP files are recommended as alternativeFor others, contact us !
