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

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
