<title>BTeam-2012-02-07</title>
BTeamers,<br>
<br>
Here is the agenda for today's BTeam meeting, at 11:00 in the MCC
meeting<br>
room as usual. We have a full plate this week with m56 setup, C100
testing<br>
(including operational considerations) and continued anticipation of
the<br>
5-pass spin-up later in the month. Thanks to Alex Bogacz for running
a good<br>
meeting last week -- we'll see you there this week. Cheers!<br>
<br>
-Todd<br>
