Thursday, September 23
- In last 24 hours:
- Early Riser summary: https://logbooks.jlab.org/entry/3910318 (4am to 10am),
- Owl summary: https://logbooks.jlab.org/entry/3910862 (10pm to 4am)
- Swing summary: https://logbooks.jlab.org/entry/3910670 (4pm-10am)
- Day summary: https://logbooks.jlab.org/entry/3910458 (10am to 4pm),
- FCAL pi0 calibration and HV tuning started yesterday at 6 am, https://logbooks.jlab.org/entry/3910786
- With PMT HVs, gains, and pedestals of run 73065
- Then, we subtracted 6V to all PMT HV resulting in a reduction of roughly 5% on all gains
- Sergey made a rapid access to the experimental hall to power cycle NIM crate
- Beni changed the TOF HV a couple of times eg https://logbooks.jlab.org/entry/3910611
- Sergey did a BCAL pedestal runs,
- Sean time calibration https://logbooks.jlab.org/entry/3910464, https://logbooks.jlab.org/entry/3910484
- Sasha adjusted tagh HV
- Issues
- Beni did look at the bleedthrough issue by analyzing timing for different run condition https://logbooks.jlab.org/entry/3910680, https://logbooks.jlab.org/entry/3910800
- After entry to the experimental MCC struggle for almost one hour to send us beam
- Sean time calibration pointed to tagm issues that Richard will address
- FCAL issues, fADC died screwing the FCAL pi0 calibration run see report diphoton invariant mass distribution per ring https://halldweb.jlab.org/primexd/phase2/fcal2021_method0_period_2-g1/
- Plan for the day
- tagm studies by Richard
- FDC straight track studies by Lubomir
