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

title="GlueX TOF Meeting, May 8, 2019">the minutes
from the meeting on May 8</a>. Ashley had a look at
the geometry. The changes needed for the upgrade should
not be too bad.
</p>
<h3><span class="mw-headline" id="Upgrade_Status">Upgrade
Status</span></h3>
<h4><span class="mw-headline" id="Procurement">Procurement</span></h4>
<p>Mark reported:
</p>
<ul>
<li> The PR for 17 additional phototubes has gone into
Procurement. We should inventory the spares already in
hand at JLab.</li>
<li> Polishing supplies that Paul requested were ordered
from MSC. They should arrive at FSU tomorrow.</li>
</ul>
<h4><span class="mw-headline" id="Engineering_Work">Engineering
Work</span></h4>
<p>Tim reported:
</p>
<ul>
<li> Everything in the Hall is ready to go.</li>
<li> Nothing will be done until the DIRC installation is
complete, probably several more weeks.</li>
<li> JLab has the drawings in hand for the brackets and
will send them out to be made.</li>
<li> Collars will made at FSU.</li>
<li> Paul reports that they have reviewed the drawings
Stephanie Worthington sent and they look good.</li>
<li> Paul expressed some misgivings at the design of the
racks to store the modules when they arrive at JLab.
He and Tim will discuss this further.</li>
<li> The gluing fixture will be mounted in the Hall as
it was during the initial installation.</li>
</ul>
<h4><span class="mw-headline" id="Construction">Construction</span></h4>
<p>Paul reported:
</p>
<ul>
<li> The scintillator bars have arrived at FSU. The
boxes will get opened tomorrow. Inspection routine
will be performed.</li>
<li> Paul will be sending in an order for more RTV and
primer.</li>
<li> The current batch of light guides are ready to have
their ends trimmed off.</li>
<li> The ESR forming device is getting made.</li>
<li> Paul has been thinking about the beam support box
needed for air light guides across the beam hole.</li>
<li> Ashley asked if we would need lucite shielding in
the new configuration. The DIRC will provide some
level of shielding but not over all of the TOF near
the beamline. This will require further thought.</li>
</ul>
<h4><span class="mw-headline" id="Software">Software</span></h4>
<p>Paul pointed out that there are many software tasks
that need to get done to support the new configuration
beyond the geometry specification.
</p>
<ul>
<li> HV and scaler guis</li>
<li> Monitoring histograms</li>
<li> HDvis and hdview2</li>
<li> TOF reconstruction</li>
<li> TOF calibration</li>
</ul>
