[BTeam] Reschedule: Tuesday beam studies 9/15

[Michael Tiefenback]

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.

I left the Bteam in the reply list in case others want to contribute to the discussion.

Colleagues,

Given that the safety briefing is Tuesday, I will propose to the RCs tomorrow that the beam studies be done Monday.

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?

Jay

Reza and colleagues,

I told the morning and 1330 meetings that we would be taking a full
eight hours next Tuesday, likely starting at 0900.  Test plan order
needs to be decided.  Hall C would like an hour access, not compatible
with Smart Alarm test plan or BNNT test plan.  Dennis's RayTrace test
plan is compatible.

http://opsweb.acc.jlab.org/CSUEApps/atlis/task/21000 RayTrace 1.5 hr

http://opsweb.acc.jlab.org/CSUEApps/atlis/task/21151  Smart Alarm 4 hr

http://opsweb.acc.jlab.org/CSUEApps/atlis/task/21234  BNNT 2 hr

Suggested order:

RayTrace so RadCon can support Hall C entry during normal hours.

restore CW through empty target to Hall C

Smart Alarm

BNNT Can this be parasitic during tune beam portion of Smart Alarm?
      If this falls off the table due to over-run of the two above, we
simply continue with existing viewer flags.

Begin restoration to all halls at 1630, after swing crew turn-over.
Attempt to complete by 1700, eight hours after start.

Jay
