OK.

> One thing that definitely needs work is a resource loaded schedule.  We need a good estimate of what we think we can accomplish on a given time scale given a certain amount of manpower.  Someone should take the lead on trying to put together a gant chart with appropriate times and dependencies along with estimated material and labor costs as best we can at this stage.  It requires some serious work, but is a worthwhile exercise. Ultimately it must match to what the lab has planned as expenditures per fiscal year, but for starters, pick a t0 and plan to do things as fast as possible.

I think first we need each "subproject" to try and provide an estimate, then we can put the pieces together.  I've asked the Bates engineers to think about this a while ago and said "end of summer" I'd want to seriously discuss a schedule.  So, I'll email them tomorrow and try and get that really moving.

On our end, we basically have the box and the mirrors as step 1, then a water circulation system and something for mirror alignment and calibration of the focusing system for later.  

We should know before the review whether both our mirror options work.  We can then give ourselves, e.g., until the end of 2015 to try some custom coatings, etc, to improve, but then we should fix the design and make the mirrors.  That should be quick with these designs.  

I've had a hard time getting anything resembling a schedule on the box.  I think we need to decide first whether there's any use in building a 1/2-scale prototype or not.  It may be that we just build the full thing.   Either way, I think we need to press the engineers to provide a schedule that they can meet that gets it done by summer 2016.  

We can plan on getting the water circulation system and calibration stuff going once the mirrors and box are well underway and I'm sure still get them done in time … or perhaps the Hall-D engineer (or whoever) wants to deal with the circulation system?
