Meeting Information
- Meeting Place: Virtual - Bluejeans
- Meeting Time: Tuesday, 11:30 EST
- Meeting Link: Refer to the weekly reminder email or calendar event for connection information.
Current Tasks
- Burcu
- Looking at pi/e- ratios for X>1 data.
- Decide on Noble Gas Cherenkov gas mix, hopefully for upcoming week
- Casey
- Write-up calibration procedures for XEM hodoscope, and calorimeter.
- Illustrate the usefulness of the diagnostic plots.
- Run the XEM model for all EMC settings
- Find what is happening to the YTrack= -2.5 blocks pulseInt
- Open the reference time windows for the 2019 data slightly. Include random hits, which should be removed by good electron cuts.
- Work on tracking in 2018 data. Pruning algorithm work
- Ali from Pion_LT running has some scripts / plots to help in this process.
- Possibly narrow the windows to select just the main peak?
- Dave
EMC ratio anomaly, where it is not yet correct.
- Abishek
- Working on the point-to-point dependence of the error on acceptance.
- Must add ‘added error’ to all momentum settings.
- Added error is until the Chi-2 value goes to ~1 per DOF. This is the ideal value, and this will give us an idea of the point-to-point error associated with the acceptance. **
- Possibly combine the two settings that have okay ratios (Data/MC) across the acceptance.
Systematic tracking efficiency is hard to pin down. Rel. Uncert. Comes from Deb’s study from rate dependence.
- Cameron
Recently Completed
- Aishek
- Isotopic purity assessment of boron targets
- Carbon target EMC ratio with Dave M's boiling slopes. (still 2% off)
- Looked at the EMC ratios with mc-single-arm detector checks turned off.
- Dave
- Log entry on cryo target density uncertainty
- Look at target boiling difference between Dave Mack and our values.
- Burcu
- Comparison of pi/e- ratio to EMC results.
- Casey
- Set up analysis location on CDAQ machine (XEM-2022).
- Ran the hodoscope calibration and improved the fit range of velocity and cable length difference.
- Looked at possible problems with X>1 calorimeter calibration.
- Checked 2019 kinematicaly forbidden range
- Cameron
- Many, many shifts.
