[Halld-pid-upgrade] TDR

[Michael Williams]

The CLAS RICH project management is quite detailed, much more than in a typical TDR, so I'm fine with not putting that much detail in … but we should have the "who's responsible" for each thing in the TDR, and an approximate timeline and budget.   We can hammer out the final details after the review, which makes sense as some issues may need to be addressed. 

BTW, Curtis and Matt, when do we *want* the focusing box done?  The Bates engineers are busy on several projects, and so I need to push to get things done on a schedule, so I need to know what schedule we're shooting for.   I think the things that set this time scale are:  When do we expect to have purchased all the PMTs?  When do we expect to be running in 2017?  

Let me know your thoughts and if I've missed any other important constraints.   Once we choose a target, I'll try and sort out a credible schedule.

I posted the CLAS12 RICH "Program Management" document on the wiki https://halldweb1.jlab.org/wiki/images/d/d8/RICH_PMP_2014March21.pdf, so if we follow this example this document is separate from the TDR and contains all the information about schedule, budget, etc.  Note: this management document wasn't required as "pre-brief" material for the RICH review, but instead described in a talk during the review and the document finalized with JLab management and DOE ~6 months later.

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'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.

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.
