Minutes

Attending: Alex, Andrew, Beni, David H., David L., Elton, Ilya, Mark, Nikhil, Rory, Simon

1. Previous CPP meeting: Nov 24, 2021
2. Announcements
   • Current experimental run is being extended, but details are still uncertain
   • Next Tuesday Dec 7 at 3:00 pm we will have a meeting with Richard to coordinate the moving of the microscope in early Jan.
3. Action Items
   • Andrew is still getting some errors in generating pion pairs. He and Elton will meet this afternoon at 4 to resolve the problem.
4. Software/Calibration for CPP (David, Alex and Sean)
5. PID + AI
   • Nikhil is working on quantifying of the uncertainties.
   • Data for AI (Andrew)
6. CPP and NPP Readiness Review
   • Report on MWPC Testing (Elton)
   • Rory has provided some comments to the text, which have been incorporated.
   • The conclusion paragraph was reviewed and edited to reduce emphasis on size of electronic noise.
   • Elton will complete changes and provide the report to the ERR committee.
7. MWPC Testing
   • FMWPC Log Book
   • Beni: Would like to replace the problematic FADC-250 (scintillators) in order to evaluate the potential time (i.e. position) resolution of the scintillators that can be obtained with the flash. He is investigating the option for spares. Elton: The chambers will still be available in Jan and it should be easier to find a FADC-250.
8. CPP and NPP Experiment Configuration
9. Target (Rory)
   • The PRIMEX Pb target has been pressed flat. Rory will take some photos for the CCP Design meeting tomorrow.
10. Electronic Configuration (Beni)
