TO DATE : PROBLEMS & SOLUTIONS
Deformation of structure
after EB welding
Anomaly spotted
and traced
MRBs
(internal & subcontractors)
Deformation max. :
≈ 400 µm on 150 mm plate
Angle iron added
Impact on FM : None
Structure modified accordingly
No delta qualification expected
Implementation
of solution

OPEN ISSUES AND CRITICAL AREAS
ELECTRICAL ISOLATION
SPIRE ECR issued - Recently agreed by PACS (Feb. 15)
Impact : - need to identify/qualify solution
- but cooler already built
- planning : to be evaluated, but some margin
available today
KEVLAR TENSION
development of dedicated tool
- various solutions being evaluated

CONCLUSION
•
•
•
•
•
No major problems to date
CQM first thermal tests : ≈ April
STM available end of March
Electrical isolation : to be adressed
Kevlar : experiments continue
data built up
• out of SBT "territory" : cryostat straps need attention
