of minutes from the previous meeting</span></h3>
<p>We looked at the <a
href="https://halldweb.jlab.org/wiki/index.php/GlueX_TOF_Meeting,_August_16,_2016#Minutes"
title="GlueX TOF Meeting, August 16, 2016">minutes
from August 16th</a>. Since the last meeting, Beni has
produced updated plots of efficiency versus run number
with error bars.
</p>
<h3><span class="mw-headline" id="Run_Plan">Run Plan</span></h3>
<p>Beni and Brad have been working on new code to get an
estimate of good starting values of the high voltage
based on the HV scan done at the beginning of the Spring
2016 run. It plots the pulse amplitudes versus
end-to-end time differences. The idea is to find, for
each tube, the lowest voltage that will put the pulses
above discriminator threshold for a minimum ionizing hit
at the far end. These results will have to be adjusted
for long-term gain reduction suffered during the run.
The exercise will be repeated with beam data once that
is available.
