<title>BTeam-2012-03-27</title>
BTeamers,<br>
<br>
Here is the agenda for tomorrow's meeting -- moderately packed, but
not much to speak of in terms of studies this week since all studies
are opportunistic because of the heat/activate and to recover some
physics run time. Please bring comments on priorities for the
campaigns (C100, PePPo, Modeling, Moller, others) to the meeting,
since some time will be spent discussing the strategy for the end of
the run.<br>
<br>
5-pass setup should go more smoothly with the trim card problem fix
in the MQA9A20 quad (e1717552). Tief may also want to comment on BPM
response (e1717544) and the backout of MO FM input changes because
of phase noise (e1717582).<br>
<br>
See y'all tomorrow at another exciting BTeam meeting!<br>

TODO Pathlength system sensitivity issue to be
addressed by Musson, biases?

<li>
TODO Phase knob for NL pathlength scope is
non-functional; SL works. Again possibly a Musson
problem.

TODO Complete setup of NL pathlength for 5-pass,
since present setup is not finalized
Pass change expected for Thu 22 Mar Day
