[Halld] Weekend Run Notes

[Sean Dobbs]

Dear Colleagues,

Please find today's notes at the following page:
https://halldweb.jlab.org/wiki/index.php/Run_Planning_Meeting_Notes,_Mar_2_-_Mar_8,_2017#Sunday.2C_March_5

Brief summary: After productive day and swing shifts, where 2.3B triggers
were collected, around midnight problems were noticed with the trigger.
The problems were traced down to a bad fADC board in the FCAL, and stable
running was established with the board disabled.  In the morning, Alex
Somov found a replacement board, and by noon we were back to nominal
production running.  In the meantime, data was taken with low photon flux
for systematic studies with the hole in the FCAL.

Cheers,
Sean
