Assumptions retained for the SC link at Point 7

  • Find a routing for a 200mm semi-rigid pipe

~500m long from service modules in RR73/77 to the DFB connections in TZ76 gallery

  • Minimum bending radius of 1,5m (to be

experienced)

  • Leave free the transport areas in tunnel and

in TZ76 gallery

Routing Options – RR73 & RR77 service areas

  • Very preliminary, need input on the design of the

cryostat/service module for a detailed study (Jan 14 ?)

Routing Options – UJ76 junction

  • Tunnel to UJ76 service area: existing ducts are full!
  • New “small” ducts must be drilled
  • UJ76 to TZ76 gallery: 2 main options
  • without new long ducts
  • with 2 new long ducts ( ̴19m each)

Routing Option 1 – UJ76

  • Without new long ducts

Routing Options – UJ76

  • Overview of the two options: 1st option (no long ducts)

requires more bends and smaller bending radius

Hard Points

  • RR73/77 to LHC tunnel:
  • Many constraints due to shieldings, metallic structures

and supports

  • need design of the service module
  • Cross over the transport monorail
  • Only one practical solution in the LHC tunnel and in

the TZ76 gallery!

  • Crossing of collimation doors
  • Action already anticipated on their design
  • UJ76 crossing: many bends in multiple directions

Open Points

  • How to connect the link to the service module ?
  • Vertically ? Horizontally ?
  • Connecting DFB’s in TZ76 gallery:
  • Do we install equipment close to their DFB ?
  • Or do we concentrate DFB’s for shorter links ?
  • Constraints on the SC link ?
  • Supporting? Fixed points? Limited space for that

slide-23
SLIDE 23

Open Points

  • “Accessories” on the link inside the tunnel:
  • Instrumentation?
  • Services (piping for He return, controls, etc…)?
  • RR devices to be relocated in TZ76 ?
  • Inventory under progress (converters, lead control,

etc… )

  • Size of DFB elements to be transported? Space

required for assembly and maintenance?

Conclusions

  • Space is very limited and constrained in the

underground areas.

  • Further integration of the SC links requires:
  • Details about service modules and DFB’s;
  • Details about ancillary equipment.
  • The real challenge is how to transport and

install two ̴500m long “snakes” through curved passages – We need experience there.
