<h3><span class="mw-headline" id="Announcements">Announcements</span></h3>
<p>Paul reported that the high-voltage crate and ADC,
shipped from JLab, arrived at FSU last week.

<h3><span class="mw-headline"

of minutes from the previous meeting</span></h3>
<p>We reviewed the <a

title="GlueX TOF Meeting, August 22, 2017">minutes
from the meeting on August 22</a>.
</p>
<ul>
<li> Beni updated the global offset for the TOF that
fixed the 300 ps offset in t<sub>TOF</sub>−t<sub>RF</sub>
that Paul Mattione had reported as of the last
meeting.</li>
<li> Beni finished the calibration pass on the the data
to fix the offset in the times of the TDCs relative to
corresponding ADC time. These constants have now been
put into the CCDB. Previously these tables were filled
by Sean using Mike Staib's method.</li>
<li> Beni updated the calibration document to reflect
the use of amplitudes in the walk correction, the
measurement and correction of the "300 ps" global
shift, and the ADC vs. TDC timing calibration.</li>
</ul>
<h3><span class="mw-headline" id="PMT_testing">PMT testing</span></h3>
<p>With the arrival of the equipment mentioned above,
Sasha is planning on starting testing next week. He has
some preliminary software for the new ADC. Paul told us
that they have undergraduate students ready to help with
the job.
</p>
<h3><span class="mw-headline" id="Counter_Reconfiguration">Counter
Reconfiguration</span></h3>
<p>Paul will give a talk at the collaboration meeting on
this subject, including work planning and costs.
</p>
<p>On a related note, we agreed to discuss the
collaboration meeting agenda further offline in the
coming days.
</p>
<h3><span class="mw-headline" id="NIM_Paper">NIM Paper</span></h3>
<p>Not a lot of progress has been made. Mark repeated his
offer to gather materials and place them in the proper
Git repository.
</p>
<h3><span class="mw-headline" id="Meeting_Time">Meeting
Time</span></h3>
<p>We decided to move the meeting one hour earlier, to 10
am every other Wednesday. Mark will reserve a room.
