<p>The planned target change to CH2 yesterday morning happened during machine downtime (vacuum valve was stuck)</p>
<p>The bad tile that was crashing the DAQ was removed from the configuration thanks to Valery and Nathan. That alarm and recovery procedures were amended as needed.</p>
<p>Around 1:35pm beam became available and by 2:10pm DAQ and MON12 were running. We verified that the raster looked good and went to production data taking on CH2 at 8nA. </p>
<p>During Swing at 4:30pm beam delivery stopped for Hall-A setup and at 6pm MCC called to inform us that the switch board panel which controls the dipole bringing beam to Hall from BSY had lost all power. At 8pm we were informed that the issue was due to an earth leak of Hall-A dipole power supplies and that it may be possible for us to take beam.</p>
<p>By 9:20pm we were back in production running at 8nA (around 11:30pm Hall was taking 3uA).</p>
<p>Owl shift was relatively productive data taking until around 5am when the orbits to B/C/D need correcting (due to turning off Hall-A dipoles). Notable event that 2H01 x drifted to -1.6mm. MCC have this as the set value. We corrected them to -1.8mm.</p>
<p>Plan for today is to take production data on CH2 at 8nA.</p>
<p>The RG-C RC meeting will be at 2:15pm today to account for the 1:30pm MCC/OPS meeting. Susan will take over as RC.</p>
