<p>Thunderstorms last night affected swing shift, followed by a 2K cold box trip, causing beam down for a while <a href="https://logbooks.jlab.org/entry/3818860">https://logbooks.jlab.org/entry/3818860</a></p>
<p>07:55 MCC did a harp fitting this morning <a href="https://logbooks.jlab.org/entry/3818888">https://logbooks.jlab.org/entry/3818888</a></p>
<p>08:02 Day shift expert noticed BONuS alarms were still disabled and reactivated them.</p>
<p>08:30 MCC calls to send beam to tagger dump. Day shift expert follows procedures and prepares for this. Solenoid and tagger ramped to nominal settings for BONuS12 calibration <a href="https://logbooks.jlab.org/entry/3818898">https://logbooks.jlab.org/entry/3818898</a></p>
<p>08:45 Having beam on tagger. Working on establishing positions. Tagger has tripped a few times.<br /><a href="https://logbooks.jlab.org/entry/3818890">https://logbooks.jlab.org/entry/3818890</a></p>
<p>09:35 Waiting on CW beam. </p>
<p>10:40 Beam down for about an hour with recertification for Hall C power supply <a href="https://cebaf.jlab.org/dtm/open-events?event_id=6634">https://cebaf.jlab.org/dtm/open-events?event_id=6634</a></p>
<p>11:41 MCC calls to pulse then readying to deliver tune-mode beam.</p>
<p>12:35 Recovery in N. Linac in progress <a href="https://cebaf.jlab.org/dtm/open-events?event_id=6635">https://cebaf.jlab.org/dtm/open-events?event_id=6635</a></p>
<p>15:40 Checked in with MCC. They said about half an hour before beam can get sent to the hall. </p>
<p>16:13 Mohammad made a quick hall access to check on issue of hall fish-eye camera not working, found it was due to no power in outlet. <a href="https://logbooks.jlab.org/entry/3819010">https://logbooks.jlab.org/entry/3819010</a></p>
<p>16:17 Hall goes back to beam permit. Beam should return soon. </p>
<p>16:29 Since there's time, we had Will Phelps go ahead and take LED runs for HTCC calibration data. Eugene took solenoid to full field for this, then will take back to nominal setting after the LED runs are done. </p>
<p>18:51 Will finishes LED runs for HTCC, turns it off. Eugene taking solenoid back to nominal current setting.</p>
<p>19:09 Accelerator having problems due to tripping from the storms coming in <a href="https://cebaf.jlab.org/dtm/open-events?event_id=6635">https://cebaf.jlab.org/dtm/open-events?event_id=6635</a></p>
