Saturday, January 14
Past 24 hours
- first beam that registers on BCM to hall on Friday at 23:00
- since then on and off again tuned beam to tagger hall but no usable beam yet
- observe frequent halo counter trips
- Shift Summary
- ABUs: 0.0 h
- Data Summary: ~0 B triggers on empty target
Issues
- Covid incident levels high; mass wearing onsite mandatory
Plan
- We are still at the very to of our run plan; item 3, ion chamber calibrations is first step
- Link to runplan: https://halldweb.jlab.org/wiki/index.php/Run_Coordination_Meetings:Spring2023#Runplan
- There will be 9 am meetings with PD over the weekend, followed by a brief run coordination meeting at 9:30 pm
- Fill target once beam delivery starts.
Friday, January 13
Past 24 hours
- HCO and last preps finished shortly after 5 pm
- No beam to hall yet
- Shift Summary
- ABUs: 0.0 h
- Data Summary: ~0 B triggers on empty target
Issues
- Run Control did not work last night when crew tried cosmic data; lost a sock
- Covid incident levels high; expect notofaction of mask mandate, or better start wearing one now.
Plan
- We are still at the very to of our run plan; item 3, ion chamber calibrations is first step
- Link to runplan: https://halldweb.jlab.org/wiki/index.php/Run_Coordination_Meetings:Spring2023#Runplan
- There will be 9 am meetings with PD; should we have a meetings over the weekend as well?
