[PEPPo] [Fwd: Beam Studies for Next Thursday]

[Joe Grames]

Dear PEPPo Collaborator,

Although subject to change we should plan for ~8 hours of beam studies 
this Thursday beginning sometime shortly after ~9am.

*Sue *- please let me know if you would like an iteration of working on 
the PEPPo collimator software.  if yes, we just need to coordinate a 
reasonable time slot because other beam tests depend upon "using as-is" 
the collimators, at least to retract them out of the way.

*Scott *- if you find yourself ready this week to implement any of the 
magnet wrappers this could be coordinated; if not, I will lobby for time 
~next week.

*Erica/Riad/Eric* - we should discuss by Wed the daq status and agree on 
the sequence of tests; ideally we put the daq through as many conditions 
as possible, and measure at compton at least pita induced charge 
asymmetry, maybe a physics related asymmetry; we can collect background 
data too

*myself *- i will focus on testing various run conditions that help us 
prepare for experiment: higher beam current on target foil, changing 
beam energy, understanding position of spectrometer viewer

-Joe

Expect to hear about a possible change to the  schedule that will impact 
the pass configuration after the Energy change on Thursday.  
Specifically, the C100 folks should prepare for high current 3-pass 
running to Hall-C from April 20th to April 26ish.      This beam loading 
environment was to occur during the last six days of the run, but 
Physics is considering moving it up.   This news might alter the 
proposed Beam studies plan below.   The number of hours in the Beam 
Studies bank is 19.
