<p>Received ~22uA and continued tritium data taking. Few hours of downtime during owl. Otherwise smooth running during swing and owl.</p>
<p>We will keep taking data with tritium target. Currently the plan is changing to hydrogen on Friday. No momentum/spectrometer angle changes, only target.</p>
<p>Fixes:<br />
- Aerogel channel with unstable gain (A2-3R): <a href="https://logbooks.jlab.org/entry/3621929">https://logbooks.jlab.org/entry/3621929</a><br />
- LQ3: <a href="https://logbooks.jlab.org/entry/3622009">https://logbooks.jlab.org/entry/3622009</a><br />
- LHRS F1 TDC resolution lock failure (slot 16): <a href="https://logbooks.jlab.org/entry/3622128">https://logbooks.jlab.org/entry/3622128</a> Alexandre changed LHRS F1 bin size from 56 ps to 58 ps. Updated analyzer to show the warnings up to 10k times instead of 10. The same warning did not come back so far. Analyzers are checking timing distributions.</p>
<p>Reminder:<br />
- Pay attention to the beam stability (BPMs, energy lock/FFB) and raster.<br />
- Check the truck ramp door indicator (orange cone in the camera screen) from time to time</p>
