5. Scope of CERN SC RF Activities Status Report for A&T Sector Meeting 18 Nov’13 SC RF Organic structure RF Cavity Design, Production & Testing RF Group is the Equipment Owner: RF Design is driven by BE-RF Advice and design by EN-MME for mechanical engineering and manufacturing Advice from TE-VSC for surfaces treatments and coatings RF Production is the responsibility of BE-RF Can decide to go for an inside or outside production Know-how preservation in-house is taken into account for decisions Production includes several prototypes for TE-VSC to validate surface treatments and coatings Responsibility for surfaces treatments & coatings stay with TE-VSC Assembly of cavity in test bench is the responsibility of BE-RF Happens that TE-VSC help in bld252 (assembly) or in SM18 (leak testing) RF testing is the responsibility of BE-RF TE-CRG provides cryogenic facilities and assistance if required BE, TE, EN Departments Summarized by José Miguel JIMENEZ 5

(3/3) Crab Cavities EN-MME to take over from TE-MSC for the cryostat design BE-RF to organize all details of this transfer of responsibility and identify urgent milestones includes SPS test bench Nothing is changed for TE-CRG and TE-VSC responsibilities BE-RF to take responsibility for the assembly of the cavity modules EN-MME to help with all utilities and tooling required for the assembly of the module TE-CRG and TE-VSC will stay partners for the assembly and testing phases BE, TE, EN Departments Summarized by José Miguel JIMENEZ 8

9. Scope of CERN SC RF Activities Status Report for A&T Sector Meeting 18 Nov’13 CERN Expertise & Infrastructures Expertise (1/2) Expertise exists but is spread in the 3 Departments of the A&T Sector BE-RF, TE-MSC, TE-VSC, TE-CRG, EN-MME, EN-STI Actions have been taken by: BE-RF to strengthen the SRF Section EN-MME to strengthen the ED/ES Sections Commitments have been taken by: TE-MSC to help with the assembly of the first two HIE-ISOLDE modules TE-VSC to provide Vacuum assistance and give access to the AL40-30 industrial contract (Manpower already defined) TE-CRG to provide Cryogenic expertise and assistance in testing facilities BE, TE, EN Departments Summarized by José Miguel JIMENEZ 9

10. Scope of CERN SC RF Activities Status Report for A&T Sector Meeting 18 Nov’13 CERN Expertise & Infrastructures Expertise (2/2) To stay at the fore front of the SC RF technology, CERN needs: To strengthen the RF expert team for cavity design; the RF Superconducting expertise. To reinforce the coating unit to be able to develop new technologies & processes; To keep the manufacturing expertise (eb welding, brazing, spinning…); To make available the resources for cryostat assembly (disassembly) and RF testing. External Collaborations are important BUT need an overall coordination Priorities shall not be fixed ONLY having Projects in perspective CERN Big picture shall stay the driving line Scientific/Technical cases need to be discussed and SC RF CERN community shall get involved in the discussion of priorities and opportunities BE, TE, EN Departments Summarized by José Miguel JIMENEZ 10

11. Scope of CERN SC RF Activities Status Report for A&T Sector Meeting 18 Nov’13 Closing Remarks Excellent atmosphere in the discussions SC RF priority is understood and the global picture is endorsed Need to have a “Coordinator” and “Coordination body” for the SC RF activities Erk JENSEN has been appointed as Coordinator and Chairman of the Coordination body Proceed to a complete evaluation of the situation Review “the ambitions” of all players and define lines of actions, priorities and resources Chair meetings involving all SC RF players (once/month?) Define the SC RF as seen by BE-RF Steer interactions of Project Leaders with groups in charge of RF WPs Priorities have been recalled LHC Spares / HIE-ISOLDE / HL-LHC Crab / SPL / Others BE, TE, EN Departments Summarized by José Miguel JIMENEZ 11
