<br><br>Monday acceleration configuration change was discussed briefly.<br>

<br>
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.<br>

<br>
Wednesday beam studies<br>
<br>
0830-0900 allsave, fopt, etc.<br>
<br>
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.<br>

<br>
1000-1100 Linux energy lock test, parasitic beam to halls possible<br>
<a href="http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12266">http://opsweb.acc.jlab.org/<u></u>CSUEApps/atlis/task/12266</a><br>
<br>
1100-1730 PEPPO no beam to halls<br>
<a href="http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12299">http://opsweb.acc.jlab.org/<u></u>CSUEApps/atlis/task/12299</a> 3h<br>
<a href="http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12300">http://opsweb.acc.jlab.org/<u></u>CSUEApps/atlis/task/12300</a> 2h<br>
<a href="http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12199">http://opsweb.acc.jlab.org/<u></u>CSUEApps/atlis/task/12199</a> 1.5h<br>
<br>
1100-1730 C100 parasitic testing, ends when PEPPO does. If the lock testers want to work only in the injector, this could start earlier.<br>
<a href="http://opsweb.acc.jlab.org/CSUEApps/atlis/task/12297">http://opsweb.acc.jlab.org/<u></u>CSUEApps/atlis/task/12297</a><br>
<br>
1730-1930 restore (hopefully only one hour)<br>
<br>
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.<br>
<br>
-----------------<br>
No maintenance is planned. If there's some RF recovery that can be done without entry, consult Steve.<br>
