of minutes from the December 5 meeting</span></h3>
<p>We went over the <a
href="https://halldweb.jlab.org/wiki/index.php/GlueX_TOF_Meeting,_December_5,_2018#Minutes"
title="GlueX TOF Meeting, December 5, 2018">minutes
from last time</a>. See the sections below for the
discussion.
</p>
<h3><span class="mw-headline" id="Calibration_Status">Calibration
Status</span></h3>
<p>Since last time Ashley has calibrated the last handful
of runs for Fall 2018. She also resolved the
Beni-script-ambiguity issue mentioned last time. She
urged Beni to commit the new "four file" version of the
scripts to the GitHub repository.
</p>
<h3><span class="mw-headline" id="Lucite_Shield_Geometry">Lucite
Shield Geometry</span></h3>
<p>After the last meeting Ashley consulted with Thomas on
a simulation configuration. She will run with a
single-particle gun event generator using geantinos.
Beam background will be turned on and the simulation run
with and without the Lucite shield. Rates will be
compared. Thomas had to supply one small tweak to
MCwrapper to control the beam current setting.
</p>
<h3><span class="mw-headline" id="Upgrade_Plan">Upgrade
Plan</span></h3>
<p>We looked at <a rel="nofollow" class="external text"
href="https://halldweb.jlab.org/talks/2018/TOF-Mod-Nov2018.pdf">Paul's
presentation</a> which came in too late to view at the
last meeting. He presents an variation on Option 2 (no
new electronic channels) and fleshes out Option 3 (8
more electronic channels). Both come with corresponding
cost estimates.
