BTeamers,<br>
<br>
Here is the agenda for tomorrow's 11:00 BTeam meeting. We had almost
no studies last week, so this<br>
week's study period is a repeat of last week's schedule. We'll also
review the latest round of machine<br>
tuning ongoing today, and have a peek at our readiness for 5-pass
spinup and some comments from<br>
Tief on his elog entry about measuring bunch length with the 1A sync
light monitor. We'll see you<br>
at the BTeam meeting tomorrow! Cheers!<br>
<br>
