• Vacuum tank delivered
• Helium vessel fabrication on-going
– Geometrical non-conformity discovered after
welding of the neck
• Wall alignment out of tolerance according to
pressure equipment standards
– Solution studied to find the best way to fix it
– Reparation will start this week
– Vessel has to be pressure and leak tested after
reparation
– Delivery at CERN expected week 28-29
A. Vande Craen, V. Maire
• Thermal shield fabrication on-going
– Wall formed
– Tube brazing started
– Delivery expected week 27
• MLI
– Order passed in March
– First version of drawings received for approval
– Delivery expected week 28

Parallel advancement for HFM (2x20kA + 2x15kA)
and Cluster D leads (2x30kA + 2x15kA)
3D design of all leads is terminated (fully resistive
type)
Functional specifications (operating parameters,
instrumentation) and specifications of interfaces
will be provided in two weeks
Execution drawings on-going (sub-components,
assembly procedures)
Procurement of raw materials and sub-components
on-going
Discussions ongoing with main workshop to assess
welding procedures for HEXs
