<p>Beam arrived at the late Day shift. We started at KinC_x36_2': SHMS angle=28.76 deg, NPS=12.46 deg. MCC decided that corrector is not needed for this angle (<a href="https://logbooks.jlab.org/entry/4221863">https://logbooks.jlab.org/entry/4221863</a>). To meet the trigger rate and data rate requirement, the current on LD2 is less than 8uA, and on LH2 is less than 20 uA, on Dummy is less than 24 uA.</p>
<p>Beam are pretty good overnight. Shifters are able to finish one production cycle at KinC_x36_2', and one more hour on LH2 before Dave Gaskell came. About 0.5 C is collected. Dave Gaskell is setting up Moller measurement at 9 am.</p>
<p>However, we do have an ongoing issue. The BCM4A cavity temperature read back is lost during Swing shift at 9:55 pm according to ELog (<a href="https://logbooks.jlab.org/entry/4222017">https://logbooks.jlab.org/entry/4222017</a>), and the BCM in HCAlarm is off. But no entry regarding this issue was made until Christine found it around 6 am (<a href="https://logbooks.jlab.org/entry/4222179">https://logbooks.jlab.org/entry/4222179</a>). An expert from MCC is going into the hall shortly to reboot the controller. This issue may result the BCM4A measurements cannot be used for those runs. BCM experts should check on this.</p>
<p>The hodoscope 11x+ ADC, TDC discrepancy comes and goes overnight. Chandan took a look but we don't have a solution at this moment <a href="https://logbooks.jlab.org/entry/4222060">https://logbooks.jlab.org/entry/4222060</a></p>
<p>Bob has a script that checks scaler counts during a run to make sure no scaler clear happening during a run: <a href="https://logbooks.jlab.org/entry/4221808">https://logbooks.jlab.org/entry/4221808</a></p>
<p>There will be a RC meeting at 11 am: <a href="https://jlab-org.zoomgov.com/j/1617015555?pwd=L09IQ216dml6ZmM5ODExVjFsMX">https://jlab-org.zoomgov.com/j/1617015555?pwd=L09IQ216dml6ZmM5ODExVjFsMX</a>...<br />
