- RICH/DAQ: During prestart, RICH scalers are zeroed and then slowly come up again

It is normal.

Summary from Sunday-Day (10/2/2022) to Monday-Owl (10/3/2022)

General Summary:
- We had beam until ~4.30 am this morning. Then the beam is off until now (10.30 am). We got ABU for 328 minutes (Day shift), 311 minutes (Swing shift), and 223 minutes (Owl shift)
- During the day shift the HWP was flipped from IN to OUT
- Total accumulated CH2 events from 3 shifts ~ 504 Million events

Accumulated events (counted from the run starting time):
Sunday Day: 192.8 M (7 hours)
Sunday Swing: 196.3 M (6.75 hours)
Monday Owl: 115.2 M (6.25 hours)

Total: 504.3 M events from 17.5 hours of running time
List of good run: 17130 (IN), 17131 (OUT), 17132 (OUT), 17133 (OUT), 17134 (OUT), 17135 (OUT)

Some issues:
- DAQ: End run failed, L3DAQ6 Not responding (fixed by Sergei)
- RICH/DAQ: During prestart, RICH scalers are zeroed and then slowly come up again
- Faraday Cup: Scaler_calc1b showed high current shortly
- MVT & BMT: HV trips (S1L4 &S3L4) which fixed by power cycle

Plan:
Today we change the target to Carbon and tomorrow we swap the target to NH3. Sometime in between we flip the HWP from OUT to IN. But the plan might change due to the beam is currently off.

We will have RC meeting at 2 PM today.
