<p>Summary of the last shifts:</p><p>We got beam back yesterday at around noon.The 120kHZ timing structure came back (<a href="https://logbooks.jlab.org/entry/3764287">https://logbooks.jlab.org/entry/3764287</a>) and FTC asymmetries were bad (<a href="https://logbooks.jlab.org/entry/3764211">https://logbooks.jlab.org/entry/3764211</a>). Injector experts spend some hours to improve beam and the timing structure almost went away (<a href="https://logbooks.jlab.org/entry/3764396">https://logbooks.jlab.org/entry/3764396</a>). Kept it on this over night.</p><p>Afterwards some steering has been done to get the FTC asymmetries down and the BPM values back to the previous night (<a href="https://logbooks.jlab.org/entry/3764392">https://logbooks.jlab.org/entry/3764392</a>). Running production at 50nA over night as decided in the daily RC meeting yesterday.</p><p>During Owl shift a lot of BMT trips occurred (8) and there was a slight resteering of the beam which improved the FTC asymmetries (<a href="https://logbooks.jlab.org/entry/3764689">https://logbooks.jlab.org/entry/3764689</a>). DC occupancies at 50nA can be for found for example here <a href="https://logbooks.jlab.org/entry/3764693">https://logbooks.jlab.org/entry/3764693</a></p><p><span style="text-decoration: underline;">Upcoming</span>: We are doing a Moeller run before Hall-C's mini spin dance, followed by empty target run during the spin dance. The Wein angle will NOT change after the mini spin danc. We will continue production afterwards and maybe call for injector tuning depending on the visibility of the 120kHz timing structure.</p><p> </p> </div>
