[Hallb] [EXTERNAL] No RC Meeting Over Weekend unless Needed!

[Lamiaa El Fassi]

Dear Colleagues,

This is a brief note to let you know that I may call for a meeting later
today after noon EDT if needed, based on the decision that MCC will make
once they finish with their attempts to bring Hall B back online. We have
been down due to a high-level decision since 3 a.m., given they were not
able to deliver us beam without tripping our halo counters and bringing
down other halls. These trips are related to the same issue that halls B &
D have been suffering from related to this 80s beam oscillation. Given
there is no solution for that yet and to minimize the trip rates, they
decided to temporarily suspend Hall B overnight as all attempts to give us
a production beam or even lower at the level of 100 to 150 nA failed. This
situation was discussed at the 9 a.m. RC/PD meeting this morning, and a
consensus was reached to dedicate 3 hours of beam tuning to debug an
alternative solution to keep Hall B alive along Halls A & C. Everyone will
be informed around noon about the beam situation over the weekend. Stay
tuned, then!

Best,

Lamiaa
