<p><strong>Accelerator and Hall Status:</strong></p><ul><li>Yesterday early swing shift, Hunter did an EPR to get a calibration constant. The result was 1.7</li><li>We finished Ion chamber calibration on reference cell (H2) around 10 pm yesterday. It didn't seem prudent to start the process of establishing beam on He3 target at the beginning of owl shift, so we kept taking data on H2 overnight.</li><li>Target polarization kept rising consistantly overnight. Current polarization is <strong>37.8% </strong>according to the last NMR sweep (12:36 pm). <strong>This is the highest polarization we have seen since the start of GEn! </strong></li><li>Simona started the process of establishing beam on He3 cell right at the beginning of day shift. It went smoothly and we are taking production data since 9 am. </li><li>After going though several tuning procedure to recover from frequent beam trip MCC decided to send 43uA to Hall A and 50uA to Hall C. This seems to be the m!
 ost stable condition for running. </li><li>Target group is discussing amongst themselves to figure out the ways for optimization.  </li><li>Beam maintainance will take place on Tuesday. MCC will take beam away around 6:45am and the whole procedure will take at least one and half shift. </li></ul><p><strong>Run Plan for today:</strong></p><ul><li>Continue taking production data</li><li>Do NMR sweps every 2/3 hours</li></ul><p><strong>Let's meet today at the usual time (3:30 pm) to go over recent and future activities.</strong></p><p><span style="caret-color: #555555; color: #555555; font-family: 'Trebuchet MS', 'Helvetica Neue', Arial, Helvetica, sans-serif; font-size: 12.25px;">Meeting details:</span><br style="caret-color: #555555; color: #555555; font-family: 'Trebuchet MS', 'Helvetica Neue', Arial, Helvetica, sans-serif; font-size: 12.25px;"><span style="caret-color: #555555; color: #555555; font-family: 'Trebuchet MS', 'Helvetica Neue', Arial, Helvetica, !
