Minutes: Simona Magnet moving to Hall perhaps tomorrow. Yves has a rough plan for determining misalignment of magnet. Plan involves taking data at +/-4T fields. Need 1 minute of data at several points. Requires 3.5 hours. Simona working on HV controls for polarimeter. 24 V power supply on rate required replacement. Replacement complete and HV controls works. PMT voltage ramp now works. No update on O-rings.

Bill New comparison of G3/G4 better with G4 lead included. Azz still 0.4% different. Eric will verify using ideal quad fields in G3/G4 Azz comparison.

Erik Quad maps show significant focusing difference at dipole exit/detector. Will investigate quantitative difference in Azz at PREX CREX solutions. Will also see difference in quads scans due to new TOSCA maps.
