sPHENIX is a new detector at RHIC.

[David Morrison <dave AT bnl.gov>]

Dear Collaborators,

Thanks to Rosi Reed for taking notes during last Friday’s (September 16, 2016) General Meeting!

Cheers,

Dave and Gunther

Agenda is at: https://indico.bnl.gov/conferenceDisplay.py?confId=2390

sPHENIX news (D. Morrison):
* New brighter picture of sPHENIX is now available (https://docdb.sphenix.bnl.gov/cgi-bin/private/ShowDocument?docid=31)
* Tracker Review was positively received, the final report should be available in 1.5–2 weeks
** This report will be generally available, not just to management
* Next Collaboration Meeting is Dec 15 - 17, sign up!!

The ALD has requested a 10–20 page document detailing the scope of the BNL funded aspect of the project

* Needs to be available prior to a planned September 29 or 30 discussion with ONP
* How should this document be structured?
* What budget guidance arrangement should we assume that we are operating under?
* Should it discuss the science scope?
Ed - The budget is $30M–$35M, we should point to the technical and other documents that are already written.  This should be a “mini-version” of a project management plan as usually seen for CD–1 ... unless the ALD gives other instructions.
Some further discussion with the ALD is necessary
Jamie - Is the physics that is and isn’t part of the baseline project decided?
Gunther - Information has come out since the last documents, so its still too early to worry about possible choices.
Ed - Perhaps the Collaboration can negotiate with the ALD about what the document should contain.
We want to receive CD–0 as quickly as possible, so perhaps we should insure we know which configuration the DOE is looking for.

sPHENIX Project News (E. O’Brien)
*There is a bid on the OHCAL, the drawing package is done and 1 full module will constructed
*Tracker -> 3 layers maps + 4 layer INTT + compact TPC
* The review was well received, but we still need particulars regarding costs, especially for the sub-systems.  This requires institutions to join in as the costs vary greatly from Institution to Institution
* The executive summary of the final report will be available to anyone
* The practice talks were really important to make sure we were internally consistent and there were no weak points.  We should do this for all further reviews
*The MAPS detector would not be done only by Los Alamos -> we need institutions to commit to the effort in order to have the real costs
*We should think of the document for the ALD as a “proto-management plan”
* Cost and schedule review indicated for Nov-Dec, usually ~1 per year, though as the committee is not yet picked this may slip.  We should keep it in mind
* FNAL Test Beam Jan 18–Feb 21, 2017

To be done: tracking code needs to be cleaned up and to be put into a state where it is stable against any one person leaving 

MAPS: news and plans (M. Liu)
* There has been a lot of progress on the LANL R&D MOU
* LANL will join the ALICE ITS program as an associate member to gain experience
* MOU between CERN and BNL would be needed for sPHENIX production
* Our design may need be adjusted to account for the slightly larger existing PHENIX beam pipe
Question -> Do we know the beam pipe?  The clearance for this is 1 mm so while we know it in principle, in practice we do not know it to the necessary tolerance.
* Trying to identify other institutions to work out pricing
* Need to form MAPS consortium, determine regular meeting times
