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 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 6
Routing Options – RR73 & RR77 service areas • Very preliminary, need input on the design of the cryostat/service module for a detailed study (Jan 14 ?) RR77 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 7

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) 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 10
Routing Option 1 – UJ76 • 2 ducts 3m long from LHC tunnel to service area • Without new long ducts SC Links UJ76 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 11

Routing Option 2 – UJ76 • With 2 new long ducts from UJ76 to the TZ76 gallery 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 13
Routing Options – UJ76 • Overview of the two options: 1 st option (no long ducts) requires more bends and smaller bending radius Option 2 Option 1 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 14
Routing Option – TZ76 • Only one practical solution: under existing cable trays SC links Racks Racks Racks Links during installation 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 15

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 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 21
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 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 22
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? 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 23
Conclusions • Space is very limited and constrained in the underground areas. • Further integration of the SC links requires: • D etails about service modules and DFB’s; • Details about ancillary equipment. • The real challenge is how to transport and install two ̴ 500 m long “snakes” through curved passages – We need experience there. 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 24
