<p>Welcome to RC summary September 17:</p><p>We concluded with about 470M trigger events on NH3 with positive polarization and 1/2 wave plate in OUT positition at 1pm. Target anneal followed. There were some problems with the communication to the microwave but this was solver rather quickly. Anneal was successfull and polarization from NMR read higher than before (about 76.7%).</p><p>Due to setup of HallC, it took awhile to get beam back. We finally could start a short 30min run (16995) at 8:45pm with positive polarization. Around 9:30pm we switched to negative polarization. Negative polarization reached about -72%. </p><p>During the night shift, there were some issue with DAQ livetime which required a RICH recovery. Otherwise everything is going smoothly.</p><p>As of know, we collected about 200M triggered events on NH3 with negative polarization and 1/2 wave plate in OUT position. We will continue like that for the next shifts and switch the 1/2 wave plate at some poi!
 nt. We could run in some bleedthrough issues when HallC pushes to high current later today.</p><p>We will NOT have a RC meeting today.</p><p>Florian</p>
