<p>Summary from Tuesday-Day (10/4/2022) to Wednesday-Owl (10/5/2022)</p>
<p>General Summary:<br />
- The NH3 target was installed during the day shift. It went smoothly. Took new baseline with microwave and shim coils on (<a href="https://logbooks.jlab.org/entry/4051011">https://logbooks.jlab.org/entry/4051011</a>)<br />
- NH3 was polarized starting with 140.15 GHz. Achieve ~ 78% of positive polarization<br />
- Tagger was energized at around 3 PM as preparation for Moller measurement<br />
- Eugene and Rafael went to the Hall to check the electronic connection who read Faraday cup (FC). FC showed unrealistic high current (noise) shortly at least twice in the last week.<br />
- The beam was off until now. Expected long downtime. Half of swing shift and Owl shift was cancelled. Tagger was then degaussed, Solenoid & Torus was ramped down. Target was depolarized<br />
- This morning Solenoid and Tours was ramped up. The polarization is back (now showing ~78%)</p>
<p>Events accumulated:<br />
No event</p>
<p>Plan:<br />
- Once we get the beam, we do Harp scan.<br />
- Do Moller run with 10 nA (please note that the manual say 4 nA but we do with 10 nA)<br />
- Take production run with PROD66_PIN configuration for at least 20 M events<br />
- Take run with normal PROD66 configuration with the duration of 4 hours OR 100 M events<br />
- Continue for ~24 hours then ask MCC to change the HWP to OUT</p>
<p>We will have RC meeting today at 2.15 PM. The next RC is Alexandre.</p>
