This is the RC summary for Day Shift July 25 through Owl shift July 26.

This was another day of smooth running. The beam was good, and only a few DAQ/HV issues on our end, which were quickly resolved.
- 7/25 day shift summary: https://logbooks.jlab.org/entry/4426545
- 7/25 swing shift summary: https://logbooks.jlab.org/entry/4426847
- 7/26 owl shift summary: https://logbooks.jlab.org/entry/4427126

At the time of this writing, there are two issues that I note here:
- We have lost comms to EC sector 2 HV. This doesn't seem to be affecting the data taking. Nathan is currently working to resolve the issue. See: https://logbooks.jlab.org/entry/4427418
- The accelerator status is currently returning a proxy wide. This is site wide, not just Hall B. This issue was raised at the morning PD/RC meeting. 

The plan for the first pass separator test on Tuesday is coming into focus. Work will begin at 10 AM, and accelerator estimates that beam will be interrupted for 1-2 hours starting about 10:30 AM. We will use this time to switch targets from helium-4 to hydrogen.


ABU for last 24h

- 18.0h of ABUs ~ 75% efficiency,

- Total ABUs since April 5th: 1190.7+18.0=1208.7 --> 1208.7 / (75.5 * 24) = 66.7%

- Day 112 of 151 scheduled: 112/151= 74.2%

- BANU: 1.3h almost entirely due to ATOF HV and DAQ issues.

Plan for today:
* Production on He with 325nA

RC meeting:

We will not have an RC meeting today or tomorrow. If any issues arise, please pick up the phone and call me, any hour: 757-575-7540.
