Here is the agenda for this afternoon's BTeam meeting, 14:00-15:00
after the weekly 13:30 meeting. The first item is a reminder to send
me your strategic priorities for BTeam on or before Mon Mar 14; I'm
happy to discuss any ideas you have with you offline while
soliciting your input. Many thanks to those (Joe, Noel, Steve,
MikeS, Ryan) that have already sent me their input. Time is tight
but there is still time to do a lot before the six month SAD; we
need to make sure that we're in a good position as we move into it.
See you at the meeting this afternoon!<br>

<p>Todd is soliciting input on priorities for studies before the
6
month SAD, emphasizing strategy rather than tactics. Items
currently on the list include CEBAF baseline, MO pathlength,
thesis
topics, LOCO and model-driven optics, procedure and
troubleshooting
verifications (including ORFP), and a Mott polarimeter
precision
study.

Some coupling has been visible in injector
fopts. Jay visually inspected the injector fopt 30Hz and
noted
that they cover 175 degrees each instead of 120 degrees, so
they
include skew components if incoming beam is not centered.
Should
we replace them with MAT correctors?
