<p>Present:
</p>
<ul>
<li> <b>JLab</b>: Mark Ito (chair), Simon Taylor, Beni
Zihlmann</li>
<li> <b>FSU</b>: Brad and Sasha absent due to shift
taking duties.</li>

<h3><span class="mw-headline"
id="Calibration_Status.2C_JLab">Calibration Status,
JLab</span></h3>
<p>Beni has been working on the calibration system.
</p>
<h4><span class="mw-headline" id="Timing_Calibration">Timing
Calibration</span></h4>
<ul>
<li> He has changed the philosophy from a completely
stand-alone system, to one that can run as part of the
Calibration Train. The new plug-ins have been checked
into the Git repository.</li>
<li> He is currently correcting the configuration of his
farm jobs to allow for enough disk space to
accommodate the large ROOT files.</li>
<li> The scheme has been modified to use a global
speed-of-light in the scintillator bars, saving
unnecessary calibration effort.</li>
</ul>
<h4><span class="mw-headline" id="Energy_Calibration">Energy
Calibration</span></h4>
<ul>
<li> This is work in progress.</li>
<li> He is now using the same two attenuation lengths
for all counters (i. e., light loss is modeled as a
sum of two exponentials).</li>
<li> The code in the TOF library will have to change as
a result.</li>
</ul>
<h3><span class="mw-headline" id="mcsmear_Parameters">mcsmear
Parameters</span></h3>
<p>We reviewed <a rel="nofollow" class="external text"
href="https://halldweb.jlab.org/wiki/index.php/Mcsmear_updates#TOF">Sean's
compilation of mcsmear parameters for the
Time-of-Flight</a>. We noted that the list of
parameters is identical to those for the start counter.
Mark and Simon had discussed the parameters some weeks
ago in the context of the start counter, and were
confident that those ideas could be easily applied to
the TOF. Details of the discussion were not easily
recalled by either one, but Mark assured us that he has
notes.
</p>
<h3><span class="mw-headline" id="Monitoring_Histograms">Monitoring
Histograms</span></h3>
<p>We reviewed an <a
href="https://halldweb.jlab.org/wiki/index.php/Example_of_Monitoring_Histogram_Email"
title="Example of Monitoring Histogram Email">example
email</a> from the <a
href="https://halldweb.jlab.org/wiki/index.php/Simple_Email_Lists"
title="Simple Email Lists">"simple" email list</a>
that David, Justin, and Paul have put together. The mail
sends out links to a minimal set of monitoring
histograms, accumulated online, for runs taken during
the previous twenty four hours.
</p>
<p>We agreed that we need to designate a member of this
working group to be responsible for reviewing the
Time-of-Flight histograms daily during running.
</p>
<h3><span class="mw-headline"
id="NIM_paper.2C_Technical_Design_Report">NIM paper,
Technical Design Report</span></h3>
<p>Mark has started a draft of an updated section for the
TOF for the TDR.
