1. WP3 Required interfaces for cryostat design / integration Patxi DUTHIL SPL 3 rd Collaboration Meeting, CERN, Geneva November 12 th 2009

2. November 12 th 2009 3 rd SPL meeting 2 Goals & Motivation (WP3 specifications)  Goal Design and construct a full-scale cryomodule prototype (Part of the SPL Design Study for a Project Proposal in 2011-2012)  Motivation Demonstrate the construction capability, CM with β=1 cavities and SC quadrupoles; Validate and improve design and construction features Learning of the critical assembly phases Enable RF testing on a multi-cavity assembly (in real operating conditions) Learning of the critical assembly phases; Validate operation issues, cryogenic cooling principles and acquire experience Estimate production costs

3. November 12 th 2009 3 rd SPL meeting 3 SPL project  CNRS-IN2P3 Tasks: 1/ To design and integrate the cryostat and to provide cryostat components for one cryomodule prototype; 2/ To design and provide the supporting/guiding system for the string of cavities in the cryostat;  The deliverables: Hardware components Design and calculation reports, drawing files and design models Fully documented industrial production files:  Material spec.  Designed calculations (construction codes)  Production drawings  Assembly procedures Quality assurance and safety records

4. November 12 th 2009 3 rd SPL meeting 4 CNRS/IN2P3 contribution statement  CERN – CEA - CNRS/IN2P3 –> collaboration agreement signed 3rd SPL meeting, Since then, CNRS/IN2P3 taskforce (already) operational Work slightly began  Conceptual design (biblio…)  Vacuum vessel design  But…

5. November 12 th 2009 3 rd SPL meeting 5 CNRS/IN2P3 Planning uncompressible

6. November 12 th 2009 3 rd SPL meeting 6 CNRS/IN2P3 needs for cryostat design on time  …but Needs of general layout specifications Needs of interfaces specifications  To: Start the design and integration study by the beginning of 2010 = NOW ! → Short Term need (ST) (by end of 2009) Carry out this detailed design → Mid Term need (MT)  3 rd SPL meeting (or conceptual design period): we should fix the Short Time needs

7. November 12 th 2009 3 rd SPL meeting 7 Machine layout  Longitudinal layout: Pattern for string of cavities(Short Term) Sectorization (ST)  cryostat (vacuum, cryogenics)  beam (vacuum, diagnostic) Quadripoles(ST)  Cold/Warm  Cross sectional layout Cryostat supporting system(ST) Orientation of RF coupler (vertical): Top/bottom(ST) Cavity string supporting reference (GRP ?) (ST) 1/2

8. November 12 th 2009 3 rd SPL meeting 8  Cryogenic layout T°, pressures (ST) Elements types (valves…) and dimensions (pipes)(ST) Cooling down protocol (spec. )(ST) Machine layout 2/2

9. November 12 th 2009 3 rd SPL meeting 9 RF System  Cavity Outer diameter (LHe vessel) (ST) Mass (order of) (ST) Alignment specifications (to be confirmed) (ST) Alignment outer reference (ST) String assembly procedure(ST) Supporting mech interface(MT)  Tuner Type (geometry, motor position…)(ST) Volume(ST)  Coupler Mech. Interface(MT) Cooling(MT)

10. November 12 th 2009 3 rd SPL meeting 10 Beam dynamics  Quadripoles (if SC) Alignment specifications (ST) Expected mass and volume(ST)

11. November 12 th 2009 3 rd SPL meeting 11 Infrastructure  Cryostat handling(MT) Out of and in the tunnel  Alignment method (2, 3 points)(MT)  CERN cryogenic test facility interface(MT)

12. November 12 th 2009 3 rd SPL meeting 12 Instrumentation  Instrumentation needs (MT) Should not be neglected in cryostat integration Mostly known from users/partners Might be already specified (feedthroughs…)→ (ST)
