−
Burcu Work:
 
−
Not currently working on any analysis as of now:
 
−
Planning to do: Look at pi/e- ratios for X>1 data.
 
−
Use Abishek’s information Abishek came up with (using existing data)
 
−
Decide on Noble Gas Cherenkov gas mix, etc for upcomming week
 
−
Hopefully avail for next week.
 
−
Planning to help with analysis tasks:
 
−
Where she can start
 
−
Dave Gaskell:
 
−
*Might get done by near. 
 
−
Log entry on cryo target density uncertainty. 
 
−
Not consistent with what Dave has heard in the past.
 
−
Bill has values like 0.6%, which is starteling
 
−
Look at target boiling.  Determine difference between Dave Mack and our values.  Don’t know why they should be different.
 
−
Bill sent data for Dave to play with
 
−
EMC ratio anomaly, where it is not yet correct. 
 
−
Nievely use Dave Mack’s boiling value moves in the correct direction, so related.
 
  
−
Abishek:
 
−
Working on the point-to-point dependence of the error on acceptance.
 
−
Acceptance studies – did not include error bars on acceptance studies, and stat. error was ~1.2%
 
−
Adding error bars, very sensitive to statistical errors. 
 
−
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. 
 
−
Abishek will be looking at EMC ratio with correct target thickness.  Need to add Boron-11 final value.
 
  
−
Cameron was on Shift – Did carbon hole centering. 
 
  
−
Put files on CDAQ machine.

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.
