- Notes from the previous 24 hours:
- TAC run (evening strip chart) was finished around 10pm. Took data with both the 750um and 75um converter.
- Production started around 11 pm and has continued through the night.
- Issues:
- When adjusting a procedure, please contact the expert before doing so to make sure the changes you make are okay.
- ~1hr 20 mins of DAQ issues while the target was filling and we could not run in raw mode.
- PS scalers (Alexandre)
- Reports:
- Correlation between beam Y position and CDC HV current (Beni)
- Attenuation lengths (Lubomir)
- PS acceptance from TAC run with 1/3 of data (Sasha)
- Low Level Monitoring Report (Thomas)
- Run Plan
- Pass change this morning
- Short access to install copper and tungsten shields
- Move muon chamber back into beam line
- Production running
- Harp scan when beam comes back

- Any more systematic studies we want to do?
- Pass change this morning
