There is a recording of this meeting on the BlueJeans site. Use your JLab credentials to gain access.
TOF Calibration
Beni is re-doing the calibration for the 2019-11 period. He discovered a bug (an inappropriate initialization value) that caused some small fraction of the fits to find the true peak timing value. He also implemented a work-around for the PMT #63 problem he reported last time. He is using the time-walk correction for that channel from the last run where the ADC was behaving properly.
He has uploaded some constants to the CCDB so that Sean can get started checking results.
Data Monitoring
Sasha has been checking the monitoring plots for the TOF from time to time. He had no anomalies to report. He will continue to make the checks.
TOF NIM paper
We re-re-dedicated ourselves to the effort.
Action Item Recap
- Decide on when to ship PMTs to JLab from FSU (Mark, Paul Eugenio)
- Prepare a complete draft of the TOF NIM paper. (all)
- Paddle 18 re-calibration (Beni)
