3. Vacuum vessel update for H-ECCTD & SERIEs
Pipes for rupture disks (x2)
Turned to aluminium gasket
Helium valve(x2)
Turned to alu. gasket
Flange for rupture disk (x2) to rework by final machining
1 DN160 nozzle kept for contingency
DN100 pumping port replaced by DN160 on the top of the vacuum vessel
DN100 pumping removed for H-ECCTD and series
Supports drilling to finalize

4. Insulation vacuum seals proposals for h-ecctd & series
Elastomer: seals can be changed easily without removing the cryomodule from the beam line (maintenance operation)
Aluminium: standard diameter
Helicoflex: non standard or too big diameter

5. Insulation vacuum seals proposals for h-ecctd & series
PRINCIPLES
No permanent elastomeric seal due to radiations rate and normal ageing
Elastomeric O Ring seals for gaskets that can be replaced easily during maintenance operations (no opening of extremity covers, therefore removing of the cryomodule)
Aluminium for other gaskets with standard dimensions
Special metallic references (Helicoflex or similar) for non standard dimensions
Aluminium gaskets
