WP3 Required interfaces for cryostat
design / integration
Patxi DUTHIL SPL 3rd Collaboration Meeting, CERN, GenevaNovember 12th 2009
November 12November 12thth 2009 2009 3 3 rdrd SPL meetingSPL meeting 22
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

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

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…

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)
3rd SPL meeting (or conceptual design period):
we should fix the Short Time needs

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)
