Dear PEPPo Collaborator,<br>
<br>
Although subject to change we should plan for ~8 hours of beam studies
this Thursday beginning sometime shortly after ~9am.<br>
<br>
<b>Sue </b>- 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.<br>
<br>
<b>Scott </b>- 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.<br>
<br>
<b>Erica/Riad/Eric</b> - 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<br>
<br>
<b>myself </b>- 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<br>
<br>

<div id="content">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.<br>
