Minutes of Hall A Group Meeting September 20, 2011
1)	Bob Michaels
a)	A draft schedule for beam delivery in the fall 
and spring has been prepared by Javier. Anyone 
interested should review it.
b)	The running schedule has us running until May 18 
(the day before the open house)
c)	Beam is likely by the end of October
d)	MIE for Møller was submitted last Friday (9/16)
e)	SBS review is scheduled for October 13-14
f)	Informal discussion re SOLID is Friday September 
30.
2)	Whit Seay
a)	Pb and sheet metal for the low power dump is here
i)	Expect the W later this week
b)	Camera assembly will be ready the 2nd week in 
October
c)	BeO viewer is ready
d)	3rd Arm: expect delivery of materials any day
i)	Outstanding is the support for the magnetic 
shielding (should be OK by experiment start)
e)	Robin is making cost estimates for 7 experiments 
(approved but not part of SBS, Møller, or SOLID)
f)	Robin also making TOSCA calculations for g2p
g)	Asks what will be needed for the October 8 g2p 
review?
i)	Javier says the charge will be out later this 
week then it should be clearer.
ii)	J-P rambles on about things he might need
3)	Installation: (Ed Folts)
a)	Working with Robin on cost estimates
b)	Magnets are cold
c)	Testing power supplies
d)	The balcony is within mm?s of being centered
e)	Rerouted water around the magnet to facilitate 
the lifting mechanism etc.
f)	Beamline work continues
g)	Couple of weeks behind schedule, but believe we 
can make the November 19 start.
i)	Re starting earlier, ?we?re not that half 
full?. Possible but not likely!
4)	Doug Higinbotham
a)	Reading proposals for review of early 12 GeV 
experiments. Encourages spokespeople to supply as 
much information as possible re their needs.
i)	There?s a lot of already approved Physics (~10 
years)
b)	The JLab experiment webpage has not been updated, 
but will be soon at least for Hall A
5)	Alexandre Camsonne
a)	Writing some proceedings
b)	Working o the Intel CPU for VME. Managed to get 
it to crash!
6)	Ole Hansen 
a)	Testing Enterprise LINUX 6 for counting house 
upgrades
b)	Re e-log, is it fixed? Bob will send info to Ole.
7)	Jixie Zhang
a)	Doing simulations for g2p optics
b)	Writing reconstruction code for the target field
8)	Kalyan Allada
a)	HRS left and right DAQ are functional
i)	Took left data over the weekend
ii)	Need to check the trigger on the right
b)	3rd are DAQ is functional
9)	J-P Chen
a)	g2p:
i)	Beamline is slightly more delayed
(1)	Harp firmware needs work, hope to be 
finished by the end of the month
(2)	New BPM?s for g2p won?t be ready for 
testing till mid-October
(3)	Need the new BPM?s to get the needed 
precision? Systematic error on scattering 
angles will suffer.
(4)	Hardware for the chicane is needed. Hope 
to get it in October.
(5)	Taking beam early is not likely
ii)	Target is cooling down as planned
iii)	Writing documents
b)	SOLID:
i)	Brainstorming meeting is September 30
ii)	Visited Stony Brook and BNL. Talked with 
detector experts as needed for SOLID. They are 
willing to collaborate.
c)	Transversity: Re 2nd paper, got comments from 
referees, all positive. Will need a little more 
work but then it should be good to go.
10)	Bogdan Wojtsekhowski
a)	Shows lots of pictures and plots from his trip to 
Europe to test GEM?s
i)	Gives lots of details about the setup and GEM?s 
in general
ii)	Proper Grounding resulted in a factor of 10 
reduction in noise!
iii)	Shows the test setup used at Mainz
iv)	Testing was very efficient. Support at Mainz 
was minimal but excellent
v)	Overall got good very positive results
11)	John LeRose
a)	Putting together a management plan for SBS
b)	Had a teleconference with Hypernuclear 
colleagues. Be spectrum is ready to be shown to 
theorists as startup to writing a paper.
12)	Chas Hightower
a)	The cage in the NW corner of the 2nd floor of the 
counting house needs housekeeping. Bob says we?ll 
take care of it.
