[Bteam] Beam studies for Tuesday, March 13

[Jay Benesch]

Eight hours of work on PePPO and C100s in parallel.

C100s:

http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12167

from Riad re Injector/PePPO:

1- Injector Access (4 hours)

a) complete BCM FSD chain (Allison, Musson, Cumbia, Bruhwel)
http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12123
b) improve BCM from 50nA to 10nA and recalibrate channels (Allison, Musson)
c) complete viewer light repairs (Delacruz)
d) decommission 500keV shielding configuration (RadCon)
e) (if steel plate ready) rebuild top of Compton detector "lid" (Voutier 
+ hands)
f) Keith Welch wanted to look at spectrometer dump shielding

{I didn't hunt for the other ATLis tasks above.)

2- Beam in Injector (4 hours)

a) beam for annihilation counters in coincidence (Voutier)

b) Mott in semi-integrated mode (Suleiman)
http://opsweb.acc.jlab.org/CSUEApps/atlis/task/11849
c) Measure charge asymmetry at nA currents (Suleiman)

During recovery:

Injector chicane ray trace

It is hoped that recovery will take less than two hours.  If the halls 
aren't ready we might work on five pass ORFP since arcs 8 and 9 never 
got finished.
