  1. To note /actions from Thursday • Size of missing glue areas that should be located in QA • If no impact on cooling performance, can area propagate • Path to defining QA need and techniques • Tape dimensional accuracy/stability • Manufacturer, during co-cure • Path to understanding– Friday • Use of dB • Path to location, definitions - Friday • Who will be point of contact for users • Tape token & cooling pipes first users • Co-curing – now baseline • Specification needed for local non-uniformity – path Friday • Mounting Brackets • Path to z=0 / z=1.3 fixation – Friday • Comparison of mounted staves stability, modes – restate friday • Z=0 fixation different, z=1.3 same (fixed) • Mass to be determined • Pull forces to be measured. Path to defining what matters – Friday • Cores • Corregated, honeycomb paper/CF – path to selection Friday • Corregated much weaker across – need specification – path Friday • Path to definition of gluing method - Friday Friday afternoon is a ‘planning’ session. Proposal was to compile list of items to discuss/ plan way forward

  2. Hysol versus CGL • CGL stave cores do not seem to result in ‘free’ pipes • CGL and hysol both acceptable • In absence of surprise - baseline is Hysol • Path to understanding CGL results– Friday • Hysol stave core pipe contraction to be measured • Shipping boxes • Path to decision on number, function, complexity – Friday • Intimately connected to production programme • Cooling pipes • Baseline is 125mm wall Ti -?? • Capillaries goal to have 125mm thickness walls • Orbital welding of these is under development • Non-standard pipe dimensions is painful – 1/8”? • Did we discuss • SE445 vs IRS2125 • Also for note • Laser welding ‘not progressing’
