<h3><span class="mw-headline" id="Announcements">Announcements</span></h3>
<p>Mark announced that the renewal of the equipment loan
agreement with FSU is past due. Paul mentioned that a
large fraction of the items have been returned, but that
there are indeed a few items that need renewal.

minutes from the last meeting</span></h3>
<p>We went over the <a

title="GlueX TOF Meeting, December 1, 2021">minutes
from the meeting on December 1</a>.
</p>
<h4><span class="mw-headline" id="Gain_Balancing">Gain
Balancing</span></h4>
<p>Beni reminded us that he adjusted voltage on all PMTs
at the beginning of the PrimEx run to equalize gains.
</p>
<h4><span class="mw-headline" id="Calibration">Calibration</span></h4>
<p>Beni reported that he has completed timing calibrations
for both the PrimEx and SRC runs. The results have been
entered into the CCDB.
</p>
<h3><span class="mw-headline"
id="Long-Term_Detector_Health">Long-Term Detector
Health</span></h3>
<p>We looked over <a rel="nofollow" class="external text"
href="https://halldweb.jlab.org/talks/2022/evaluating%20status%20of%20Hall%20D%20hardware%20and%20electronics.pdf">Matt
Shepherd's email</a> announcing a session at the
February collaboration meeting on evaluating the status
of Hall D hardware and electronics. We have just gone
through an exercise of replacing PMTs identified as
having reduced gain. That experience informs much of
what we can say for maintaining the TOF into future
years.
</p>
<p>Paul will prepare a presentation.
</p>
<h3><span class="mw-headline" id="TOF_II_Trigger">TOF II
Trigger</span></h3>
<p>Mark reported that the new firmware for the TOF did not
get a trial during the last run. Sascha Somov is doing
test with it this week. Testing will have to be done
without the beam.
