<p>We went over <a

title="GlueX TOF Meeting, July 1, 2020">the minutes

</p>
<ul>
<li> Sasha has finished testing all of the 23 new PMTs.
Recall that there is one problematic tube.</li>
<li> Both of the issues on energy agreement between
Monte Carlo and data on the GitHub repositories (one
in halld_sim, one in hdgeant4) have been closed.</li>
</ul>
<h3><span class="mw-headline" id="Run_Readiness">Run
Readiness</span></h3>
<p>Beni showed plots of ADC pedestals, pulse amplitudes,
pulse integrals, and time spectra for all TOF channels
from a recent cosmic run. The pedestals had already been
adjusted by hand to the four problem channels near the
nominal 100 counts. There is a clear channel in a board
(16 channels) visible both in the pulse integral and
timing plots. Sascha Somov plans to replace that ADC
today.
