Minutes
Simona - onsite udpate
- Tested new PTMs - they are good
- Took out detector package this morning, will replace the old scintillator pmts with the new ones
- Survey - calorimeter two sides (vertically) shifted to each other, not sure if it has been that way before, talking to Eugene about it
- Target survey rescheduled to tomorrow morning
Eric - simulation update
- Applying the CREX tune optimization method to the PREX energy
- Q2 and Q4 detuned up to 10%, and for various combinations of detune checked azz with and without Q1 rate tuning
- preliminary results show levchuck corrected azz within 0.5%
- yet relatively large levchuk sensitivity compared to CREX remains problematic
Bill - simulation update
- Bill showed rate and Levchuck correction curves at PREX energy
- Similarly to Eric's concern, large Levchuk sensitivity was shown
- About 4% Levchuck correction at -2% detune for Q1
- Suggested to look into more details between settings and understand why the Levchuk correction becomes large
