Overall Production
http://ific.uv.es/~lacasta/ECproduction/
• Proceeds smoothly
– ~816 module starts
(35% of total)
• 70% tested of which
– Yield: 88% (good), 92%(good+pass)
Still OK but seems to be dropping slightly
• Components:
– No stocks building up for spines or hybrids
• Very vulnerable to component delays

Thanks to Joe Foster for summary
Overall Schedule
• Still some delay
– Foreseen to finish last module by
end June 2005
– GVA and MPI have increased
their production rates
– Could be earlier (during May) if
sites soon approaching their
agreed number of modules, keep
their production lines running.
• VLC helps MPI with middles
• NIKHEF helps Freiburg with
Inners
– Melbourne has to start very soon.
• Already pre-qualified.
UK Modules
Production Issues
•
Disk measurements showed redundancy link operation increases noise:
–
–
Trials have led to new (screened) links and requirement to change module 5.1kΩ
resistor on redundancy line
All UK modules at Liverpool now have shorted out resistor with 0Ω resistor following
procedure proposed by Freiburg
•
–
–
•
20% sample test show identical normal electrical performance after change
All new hybrids have 0Ω resistor
Disk results with these changes greatly improved, disc9C mounting to begin
Repeat of contamination/erosion of tracks on fan-in after thermal cycling.
•
•
•
Seen in one early Liverpool Module
Now seen on two MPI modules in the
same place as at Liverpool
Chemical analysis soon at CERN
•
Spine QA and delivery still critical
•
Prague CTU and Melbourne still to qualify
•
Most other sites producing at or above original
envisaged rates and UK is nearing half-way
