</p>
<p>Beni reported that everything is on in the Hall now for
the TOF. Two weeks ago he did find the HV crate turned
off.
</p>
<h3><span class="mw-headline" id="Calibration_Trip_Report">Calibration
Trip Report</span></h3>
<p>Brad visited JLab for two weeks and worked on learning
Beni's calibration system.
</p>
<ul>
<li> <b>Week 1</b>. He spent the time looking at Beni's
code, step-by-step. The commands to run the
calibration are very simple.</li>
<li> <b>Week 2</b>. He worked on understanding
multi-threading and how to do batch farm submission.
He has been asking Beni, Justin Stevens, and Paul
Mattione for guidance.</li>
</ul>
<p>The current task is to get batch submission going. He
is going to look at Kei Moriya's <a rel="nofollow"

href="https://mailman.jlab.org/pipermail/halld-offline/2015-August/002119.html">recently
announced procedures</a> for using SWIF in the Hall D
context.
</p>
<h3><span class="mw-headline" id="ADC_Calibration">ADC
Calibration</span></h3>
<p>Beni has done some additional tests on the effect of
the angle of incidence of track on energy deposition. He
finds that the angles are so small, less than 15
degrees, that they make very little difference and can
be ignored in the initial calibration at least. As
expected, when he matches TOF hits to tracks, the low
energy noise just above threshold largely disappears
leaving only hits from corner clippers. Work continues.
</p>
<h3><span class="mw-headline" id="Action_Items">Action
Items</span></h3>
<ul>
<li> Batch farm submission of calibration jobs.</li>
<li> Further work on ADC calibration.</li>
<li> Install Bryan Moffit's library into the online
system as a first step in doing the time bin size
calibration.</li>
</ul>
