  1. Access scenarios on design compromise Take concern to ITK – formulate – homework - friday • Location of opto-electrical conversion for strip detector. Path to decision – Friday • Path to EoS cooling pipe layout decision – Friday • Discrete vs continuous interconnects – path to decision – Friday • Path to confirmation of grounding baseline – Friday • To foam or not to foam that is the bend question – path to decision Friday • Path to confirmation of cooling loop baseline, including z=120 simulation – Friday • Thermal headroom utilisation in barrel stave path to choice to be defined – Friday • Barrel stave contraction – fixation z=0 or z=1.2 – path Friday • End of stave fixing arrangement design needed path to definition/design – Friday • Define stave to macro-structure stability requirements – path Friday • Path to Size of missing glue areas that should be located in QA • Tape dimensional accuracy/stabilit Path to understanding – Friday • Use of dB Path to location, definitions, responsible - Friday • Co-curing – Specification needed for local non-uniformity – path Friday • Mounting Brackets Path to z=0 / z=1.3 fixation – Friday • Mounting brackets 2e vs 1e Choice – path – confirmation of path • Comparison of mounted staves stability, modes – restate Friday • Pull forces to be measured. Path to defining what matters – Friday • Cores path to selection Friday • Path to definition of core gluing method – Friday • Hysol versus CGL Path to confirming baseline hysol – Friday • Shipping boxes Path to decision on number, function, complexity – Friday • Cooling pipes – path to confirmation of Ti

  2. LS Prototype Requirements • From perspective of mechanical issues • Define ‘baseline global support properties’ • For barrel region In 3-4 years arrive at: • Sector mimicking global support, including end-region constraints • Populated with ? 5 final 130nm design full length local supports • Dummy thermal loads • Ability to measure in several orientations • Thermal performance • mechanical behaviour at scale relevant to physics • Capable of mounting an electrical prototype

  3. Missing • Survey/Alignment - integration mostly? • En-route • Thermo-Mechanical 130nm stave

  4. Effort • Standardisation/Standardization • Monitoring of progress • AUW – 2/year • Berkley Meetings 1/year • ? • Forward strip
