Summary of Meeting Discussions:

All. Nominate secretary: (next secretary: Ashot)

All. Approval of last meeting's minutes:

Approved. You can find the previous meeting minutes here. No comments on last weeks meeting minutes.

All. New Business: Itemized below

4: nA BPM survey discussion:

Mathew Reece asked the long-standing, unanswered question: Does anybody have BPM survey data?

Discussion ensues...This survey data is needed in order to render the BPM x,y readout in absolute position relative to the Hall B beamline. Ashot mentions that Pawel should speak to Stepan Stepanyan about any possible BPM srvey data. For reference, here is Pawel's Beam Quality analysis note pdf

5: Analysis note review documentation:

Documentation of analysis note reviews and procedures are given on the secure wiki's Analysis review and discussion page.

It was mentioned that Yelena's Compton note has not been reviewed (formal reviewers are Mark and Mahbub) and that Analysis notes from Pawel (Compton) and Aram (e+e-) are due.

Eugene reminds us that new analysis notes (pi0, Compton, e+e-) are due at least a week before the upcoming analysis meeting on June 21,22.

6: Sergey's Omega meson backgroud study:

A working document describing Sergey's calculations can be found here .

Sergey considers both coherent and incoherent (including Omega + Delta(1232)) Omega photoproduction; he says there is a huge cross section for inelastic Omega + isobar production. The gamma + pi0 decay channel for these Omega's is potentially a large source of the inelastic pi0 events in our data; to better understand this, Ilya is incorporating Sergey's calculations into his PrimEx simulation and will present results soon.

Ashot requests that Sergey try to port his theoretical developments into a universal function that can be incorporated into other analyzer's Monte Carlos.

7: Instrumentaion paper discussion:

Below is a proposed list of instrumentation papers (along with main authors) that were discussed during the meeting. Ashot says that responsible peoples should produce a proposed outline for each paper to be discussed at a near future Friday meeting.

--HyCal paper (Ashot, Liping, Dustin, )

--Flux paper (Dan, Aram, )

--Combined Instrumentation paper--Entire Primex Setup (?)

--Maybe Target properties (Rory, Eric, ) by itself or simply incorporated into Combined paper?
