problem/to do list

• check/optimize space constraints SSW ? FFE
• test of connections under sheer forces (how much
  moves SSW relative to endplate under load?)
• FEE mounting bars fixation, should be adjustable
  to compensate for SSW movement
• convenient tools for closing/opening of HARWIN
  connectors
• copper cooling plates should not cover connectors
• ...

2-sector model

• setting up 2-sectors (endplate, SSW)
• one SSW fully equipped (cooling, LV, ...)
• 2 endplate sectors fully equipped with ROCs
• test/develop FEE fixation
• develop mounting strategy tools
• status
• one endplate sector available, one endplate
  sector in production,
• fully equipped SSW sector available (Rainer)

time estimate

• mounting cards (experience from ROC tests at
  GSI)
• 1 hrs to close all connectors (IROC, optimal
  conditions)
• 2-3 hrs for non-optimal conditions
• insertion of FEE
• insertion of flex cables
• border FEE difficult
• testing of connectivity after insertion
• connect RCU, cooling (card-wise or row-wise ?)
• 5 min/card (?) ? 3-4 hrs
• total 1 chamber/day/team (IROC, OROC ?)
