Dear Collaborators,

The last 24 hours has been a bit slow in terms of our Coulomb collection rate as we only collected about 0.65 C. This is due to the prolonged beam-down time for 4-pass separator work to get Hall-C up and running. Beam was taken away from us at noon yesterday and when we got beam back around 10 pm last night, beam delivery was interrupted several times due to "tuning" work. Now we continue to take data at 20 uA but the beam is unstable due to the ongoing current push to Hall-C.

Experiment progress:
-Charge collected during the last ~24 hour period: 0.65 C
-Total accumulated charge at Kin3 so far: 57.73 C (Goal 100 C)
-Total accumulated charge at Kin3 since July 9 Day to July 43 Owl: 8.21
-Effective experiment running efficiency since July 9 Day shift (ABU tot)/(AU tot + BANU tot): 85%
