As I mentioned last week, I am unavailable today to tun the BNNT test. I haven't heard anyone else step up to run the viewer test (Tief or Gubeli?). So, Jay it may fall off the list for today, Thank you.</div>

Our viewer supports have not been designed to support any heat load. I raise the question: Does CW on the BNNT flag result in heating which might have unpleasant consequences? It seems to me that placing a BNNT flag into a more readily tended piece of beam
line than Arc 7A would be better than potentially dirtying up ITV7A09. An issue for discussion rather than a forecast of disaster.</div>

<br>
Given that the safety briefing is Tuesday, I will propose to the RCs tomorrow that the beam studies be done Monday.
<br>
<br>
It has been suggested that the BNNT viewer be re-classified in CED as CW and subjected to 30 uA CW just before Hall C switches to first pass. This would be in lieu of tune beam Monday. Comments?

<br>
Reza and colleagues,<br>
<br>
I told the morning and 1330 meetings that we would be taking a full<br>
eight hours next Tuesday, likely starting at 0900. Test plan order<br>
needs to be decided. Hall C would like an hour access, not compatible<br>
with Smart Alarm test plan or BNNT test plan. Dennis's RayTrace test<br>
plan is compatible.<br>
<br>
<a href="http://opsweb.acc.jlab.org/CSUEApps/atlis/task/21000">http://opsweb.acc.jlab.org/CSUEApps/atlis/task/21000</a> RayTrace 1.5 hr<br>
<br>
<a href="http://opsweb.acc.jlab.org/CSUEApps/atlis/task/21151">http://opsweb.acc.jlab.org/CSUEApps/atlis/task/21151</a> Smart Alarm 4 hr<br>
<br>
<a href="http://opsweb.acc.jlab.org/CSUEApps/atlis/task/21234">http://opsweb.acc.jlab.org/CSUEApps/atlis/task/21234</a> BNNT 2 hr<br>
<br>
Suggested order:<br>
<br>
RayTrace so RadCon can support Hall C entry during normal hours.<br>
<br>
restore CW through empty target to Hall C<br>
<br>
Smart Alarm<br>
<br>
BNNT Can this be parasitic during tune beam portion of Smart Alarm?<br>
If this falls off the table due to over-run of the two above, we<br>
simply continue with existing viewer flags.<br>
<br>
Begin restoration to all halls at 1630, after swing crew turn-over.<br>
Attempt to complete by 1700, eight hours after start.<br>
<br>
