Minutes of Hall A Group Meeting July 31, 2012
1)	Thia Keppel
a)	Late reminder, you should have submitted your 
awards/publications for this year to Linda last Friday 
(7/27)
b)	The Radiation Badge rack in the lobby of the counting house 
will be moved because of the planned refurbishment work. 
Watch for an e-mail informing you of the new location.
c)	NSAC preparations:
i)	Hall Leaders are preparing slides re the compelling and 
unique science to be done in the coming years
ii)	EIC design report is almost done
iii)	12 GeV White Paper is almost done.
d)	Management self -assessment will look at how we do large 
installations. Dave Gaskill will head the committee who will 
be looking at g2p and Qweak.
2)	Robin Wines
a)	Møller:
i)	Shielded box is due in this Friday (8/3)
ii)	Expect delivery of the 4th Quadrupole between 7 and 21 
August. Expect to tighten the time window soon.
iii)	Re measuring the magnet, it should be 2 day?s work but 
could take between 2 days and 2 weeks depending on how 
busy magnet measuring is when we get it to them.
iv)	Overall things are going well
b)	Compton:
i)	Finishing up the field plate modifications
ii)	Almost all parts are in
c)	SBS:
i)	Working on configurations and solutions to interference 
problems
ii)	Considering different coil solution
d)	Looking at DVCS and GMp configurations
e)	Whit and Ed working on re-working the g2p girder support for 
general use (better and less work than reinstalling the old 
girder support)
f)	Looking at new coils for APEX
g)	CAD upgrade: They?ve started moving people to the new 
system. SRF has move and are testing things. Then Hall D 
will go. After that Hall A will move over.
3)	Ed Folts
a)	Møller: 
i)	waiting for parts
ii)	Hooked up AC power and control cable for the new 
Quadrupole
b)	Cryo upgrades continue
4)	Sirish Nanda
a)	Thinks there?s a solution in hand for mapping the Compton 
dipoles in the tunnel (will have to move the magnets some to 
allow for setting up mapping equipment, but should be easier 
than moving the magnet to the mapping facility and just as 
accurate)
b)	New computer for Compton is up and running. Will move both 
the old and new computers to the Hall during counting house 
refurbishment
c)	Re the mysterious cavity problem mentioned last week, may 
have found the answer. More next time.
5)	Bob Michaels
a)	Working on moving counting house computers to the Hall
i)	Discusses details
ii)	Will need some new electrical service (Jack put in a 
service request)
6)	Jack Segal taking apart the septum magnet
7)	Bert Manzlak
a)	In September we will be switching over to an electronic 
system for signatures on work control documents
i)	Two training sessions are scheduled
(1)	OSP Form Training for Reviewers and Approvers, Aug 
2 13:30-14:30 F113
(2)	OSP Form Training for Document Owners/Authors, Aug 
6 11:00-12:00 F113
b)	Counting House computers should be off or out by the end of 
next week
8)	Kalyan Allada
a)	Working on inclusive Hadron production
b)	SOLID simulation work continues
9)	Jixie Zhang
a)	Debugging the Radiative correction program for polarized 
targets
i)	Good for exclusive processes
10)	Jian-Ping Chen
a)	Just returned from China
i)	2 week program
(1)	Hadronic structure
(2)	Hadron Workshop
ii)	Much participation from Chinese groups
iii)	Several groups doing R&D work on GEM?s
iv)	Finally got the export license approved for APV25?s
b)	Chiral Dynamics workshop will be here next week
i)	Register if you haven?t already
ii)	Need volunteers for Hall A tour guides for Thursday 
(8/9) from 15:30 to 17:30
c)	Polarized 3He target lab work is ongoing
i)	Students will present poster this Friday (8/3)
11)	Ole Hansen
a)	Counting House Computer move is about 50% done. Main 
machines are already in the Hall.
b)	Saw the new ?Farm? cluster. It?s half a rack! Very spiffy 
setup. Wants one for the Counting House
12)	Bogdan Wojtsekhowski
a)	Proposed new SBS magnet coil configuration. Al and Robin are 
looking at it.
b)	Septum magnet for APEX/PREXII:
i)	Played with shims got what appears to be good field
ii)	Would like to machine the iron. Not clear we can due to 
activation problems
iii)	Looking at radiation aspects (opening to exit beam line  
seems problematic)
c)	Construction of SciFi detector continues
d)	Preparing slides for NSAC
13)	John LeRose
a)	Evaluating new APEX map from Bogdan
b)	Will be away on vacation next week
14)	Javier Gomez says Yves Roblin will check the raster settings 
with Møller quads and 11 GeV beam.
