<span class="mw-headline" id="Cable_Swap">Cable Swap</span><br>
<br>
Eric reported that Nick Sandoval and Chris Stanislav did a
systematic check of all cables in the Hall and <a
href="https://logbooks.jlab.org/entry/3320190"
class="external text" rel="nofollow">found swaps</a> for
counters 1 and 2 and for 22 and 23 going from the ST2 boards
to the ST3. The cables had been mislabeled. They are now
fixed. This explains the anomalously low rates Eric was
seeing for "counter 2" last Fall.
<br>
Eric will get the correct translation table into the CCDB
both for Fall 2014 data and for data going forward.
<br>
<br>
<span class="mw-headline" id="Status_in_Hall">Status in Hall</span><br>
<br>
Eric reported.
<br>
<ul>
<li> The new flange has been installed and the start
counter mounted on the target cart.
</li>
<li> Survey was done.
</li>
<li> The next step is to cable up the ST2s and do a check.
</li>
<li> Eric will look at a method to attached the temporary
target to the nose of the start counter.
</li>
</ul>

Efficiency Study</span><br>
<br>
Eric presented work he has done to understand hits from the
start counter in preparation for doing an efficiency study
using charged tracks. See <a
href="https://halldweb1.jlab.org/talks/2015/ST_Update_Feb_12_2015.pdf"
class="external text" rel="nofollow">his slides</a> for
details. In particular he described cuts for reducing hits
not associated with the event.
<br>
<br>
<span class="mw-headline" id="DAQ_Tasks">DAQ Tasks</span><br>
<br>
After the collaboration meeting, Werner, Eric, and Mahmoud
will get together and produce a list, like <a
href="https://halldweb1.jlab.org/wiki/index.php/TOF_DAQ_Tasks,_January_22,_2015"
title="TOF DAQ Tasks, January 22, 2015">that for the TOF</a>,
tailored for the start counter.
<br>
<br>
<span class="mw-headline" id="NIM_Paper">NIM Paper</span><br>
<br>
Writing a NIM paper has long been in the thinking at FIU. It
would serve also as a major component of Eric's thesis.
