Minutes

1. Kent - quickly reviewing what we need to get done
   • CREX calibration and verification
   • PREX calibration and verification
   • central angle calibration. PREX and CREX to compare
   • Q2, acceptance function, for PREX, CREX, and transverse running
   • Background.
     • inelastic
     • carbon
2. Siyu:
   • looking for ways to quantify uncertainty on the recoil/watercell measurment
   • One documentation question came up: where did the formula giving p0 setting vs. hall probe come from? (Note log entry halog:3748112)
   • next steps: look at central value +/- error on parameter (not RMS) to get the error from the fit on the separation
   • do this for each of the momentum settings
   • ultimately, do this for each of the holes in the sieve.
   • Also: use error propagation to see how recoil energy difference or derived scattering angle depends on beam energy, scattering angle...
3. Ryan:
   • is able to run Siyu’s code to check the optics database reconstruction
   • Next steps: will use this to start to verify the PREX database
