Agenda

Please post slides in haplog or docdb, before the meeting

1. Last weeks issues:
   • Non-symmetric azimuthal angle acceptance distributions
   • instability in Q2 measurements over the PREX-2 run
   • catalog of relevant parameters for Q2 runs (beam E, beam position, spectrometer dp, trigger hole?... others?)
   • Lead uniformity measurement vs. target lifetime (expected failure at end only)
     • Some bound from Devi's plot of widths/yields over the run haplog:4185
2. Longstanding topics
   • progress on MC simulation of acceptance function
   • Carbon fraction
   • ultimate precision of angle measurement
   • evaluation of optics db reconstruction uncertainty to q2 / acceptance function systematic error
   • inelastic contamination
