Minutes
- Reviewed minutes from last week
- Malte made a shift plan and will distribute on Google docs
- There is a need for 50 micron aluminized mylar for big holes - Scot will order
- Some of the modules show cuts in the mylar from SS straps - does not seem to be increasing as we get lower in the stack
- Eugene requesting a "forked" tool to help keep tape straight
- No shims have been observed in upper half yet - we need to document shims in the lower half as we unstack
- Planning stacking test in ESB once the G10 plates are modified - approx 2 weeks
- Sasha working with Stephanie and Arshak to determine LMS fiber lengths
- Sasha to sketch box to see where it will fit under platform
- There is a question about temperature stabilization in the box - is it needed?
- We appear to be about 2 weeks ahead of schedule with unstacking going quicker than expected
- Sasha is in charge of stacking and will make a plan
- Malte expressed that we have enough shelving and crates for all glass modules -
- may need to stack 3 rows on some shelves
- Keith and Scot to look at was to make lower shelves more accessible
- Sasha mentioned that at some point we would like to remove some of the 400 unused cables for re-use
