Information available & missing For the West Area site, integration depends on the extraction line geometry chosen. An older option (trench in TT5) is shown, but any other option will not cause major modifications or show-stoppers on CDR level. The layouts shown further-on use all the information that we have available, but a lot of information is still missing. We urgently need more input from the collaboration for each element: footprint, services (power, cooling, gas, cables etc.), “geometrical” constraints… Ans Pardons, 18/10/2012 Integration of experimental facility in West Area and CNGS 6

West Area: Issues Trench in conflict with technical galleries at 450 GeV beam (see Chiara’s & John’s talks) Magnet storage in TT4/TT5 No beamline installed, needs new magnets Needs new proton dump, radiation issues (see Helmut’s talk) Interference with nTOF (shielding, access) But: easy access to experimental facility Ans Pardons, 18/10/2012 Integration of experimental facility in West Area and CNGS 14

CNGS: Issues Linked to CNGS future plans, only first stage Awake can be planned for the moment (leave rest in place) Radioactive area: interventions are more complex Underground area: limited space available, civil engineering & access procedures are more complex But: proton dump available, some recuperation of magnets possible, access independent from LHC/SPS, fairly new services already installed Ans Pardons, 18/10/2012 Integration of experimental facility in West Area and CNGS 24

From Edda’s talk: West Area vs CNGS – Incomplete! E. Gschwendtner, AWAKE Collaboration Meeting, CERN, 18/10/ West AreaCNGS Proton beam line- To be done+ Most of it exists Prompt dose issues (muon dose) - Consequences on beam energy and/or limited number of extractions! + OK, under control Other radiation issues- Shielding to protect West Area- Target, horns! Need long cool-down Civil engineering- Needed for trench-+ to be checked whether needed. Size of experimental area+ OK- Small Access- New access system, + but experimental area nearby + Access system exists, - but long distance to experimental area Electricity- A lot must be refurbished, renewed+ Exists, - needs some modifications Cooling, ventilation- A lot must be refurbished, renewed,…+ Exists, - needs some modifications Storage- TT4/TT5 full with stored magnets, etc… area needed in LS1.  build new storage building. + No storage area Beam dump- Must be newly built, - lot of shielding needed+ Exists ……… Also More Information Needed!!
