Hi Martin,

The 20th works better for me. I have a potential conflict on the 13th as well.

All, especially Mickey and the Colorado group,

the DAQ/Trigger/MBD review was originally scheduled for Dec 13. It turns
out that the DOE moved a review that I had agreed to serve on to that
week, and I have to be in Germantown the better part of that week. Being
wedged in between the Santa Fe meeting and this, JohnH suggested we move
the TR out by a week (that would nominally be Dec 20).

If that's getting too close to the Holiday Season, we could find a day
earlier that week. I just wanted to let you know so no one feels left out.

Hello,

I have been in touch with the subsystem managers about this, but I
thought I should let the wider sPHENIX world know that this will be
starting soon. The goal is to have a document the design in a series of
presentations, and to remind ourselves what must be completed in the
Conceptual Design Report. It is a direct response to a recommendation
of the Director's Review.

I'll be asking for help in conducting these reviews from within the
collaboration, so please consider seriously requests from Jim, Don, or
me. If you are interested in volunteering, please contact me.

The charge to the CD-1 review of sPHENIX will almost certainly include
the question to the review committee:

Is the conceptual design technically sound and likely to meet the
objectives of its scientific case?

and the expectation will be that the CDR will be complete.

Ed and I think that we can accomplish this in a way that actually
benefits us by convening a series of short reviews for each of the
detector systems. The idea is that we have one morning each on TPC,
EMCAL, HCAL, CalEl, and T/DAQ with a largely technical committee of
physicists and engineers, including one "outside" person (i.e., not a
member of the sPHENIX collaboration). I will chair the committee, and
I will work with the L2 managers to select other members of the
committee (nor more than 2 or 3 other physicists or engineers, in
addition to the "outside" reviewer).

I would like to use this process to complete the CDR so that it is
ready for a Director's Review in early CY2018 and a CD-1 review in
spring of 2018, so part of the job of the reviewers is to read
carefully and make *constructive* suggestions and corrections to the
CDR. We might want to appoint one of the reviewers as a subsystem
"godfather" who will help edit the CDR.

I propose the following schedule on Wednesday mornings (there are
relatively few meetings on Wednesday):

Nov 1 HCAL
Nov 8 EMCAL
Nov 15 TPC and TPC electronics (we might need to go into the afternoon
on electronics)
Nov 29 CalEl
Dec 13 Trigger/DAQ + MBD

The outcome of this process would then be a series of meetings with
technical slides, a review report, and a completed CDR by the
beginning of CY2018. It seems feasible to me; many of you have almost
all the slides you need for this now, the CDR is in a pretty advanced
state, and we can use it also as a way to draw in more members of the
collaboration.

I actually don't think these reviews should be onerous... much of the
material has been shown multiple times, and having someone outside our
usual orbit look at our ideas might even prove useful. I'll post this
to one of the sphenix lists, but I thought first I'd make sure the L2
managers are ok with it, and this will test whether you read to the end.
