Monday acceleration configuration change was discussed briefly.

A semi-parasitic test that Qweak wants to do this weekend was discussed.
 Step 6 involves dumping considerable beam on apertures.  Joe agreed to
review and comment on it.  Email since the ATLis was submitted suggests a
follow-on ATLis this weekend.  The PD will make the call with advice from
Arne or his designee, Matt.

Wednesday beam studies

0830-0900  allsave, fopt, etc.

0900-1000 Linux orbit lock test, parasitic beam to halls possible.  I'd
like to know if these locks "fight" in the same manner as the old ones,
which suggests tune beam to a dumplet for some of the testing.
http://opsweb.acc.jlab.org/**CSUEApps/atlis/task/12215<http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12215>

1000-1100 Linux energy lock test, parasitic beam to halls possible
http://opsweb.acc.jlab.org/**CSUEApps/atlis/task/12266<http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12266>

1100-1730       PEPPO   no beam to halls
http://opsweb.acc.jlab.org/**CSUEApps/atlis/task/12299<http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12299>
  3h
http://opsweb.acc.jlab.org/**CSUEApps/atlis/task/12300<http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12300>
  2h
http://opsweb.acc.jlab.org/**CSUEApps/atlis/task/12199<http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12199>
  1.5h

1100-1730       C100 parasitic testing, ends when PEPPO does.  If the lock
testers want to work only in the injector, this could start earlier.
http://opsweb.acc.jlab.org/**CSUEApps/atlis/task/12297<http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12297>

1730-1930       restore (hopefully only one hour)

5 hours held in reserve for C100 issues when hall C changes to fourth pass
on Sunday, April 15, putting 720 uA through the C100s.

-----------------
No maintenance is planned.  If there's some RF recovery that can be done
without entry, consult Steve.
