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

minutes from the last meeting</span></h3>
<p>We looked over the <a
href="https://halldweb.jlab.org/wiki/index.php/HDGeant4_Meeting,_January_11,_2022#Minutes"
title="HDGeant4 Meeting, January 11, 2022">minutes
from the meeting on January 11</a>. Sean reported that
he found and fixed the issue with the 4 ns time offset
in CPP simulated data.

<h3><span class="mw-headline" id="Pull_Requests_on_GitHub">Pull
Requests on GitHub</span></h3>
<p>Sean described <a rel="nofollow" class="external text"
href="https://github.com/JeffersonLab/HDGeant4/pull/202">Pull Request
#202</a>, "Fix for TAGH hits for the SRC/CT
experiment." Tagger counters, at photon energies lower
than those in the microscope region are missing. This is
due their accepted energy range being set to zero,
causing unfortunate side-effects. This situation was
introduced in the solution to <a rel="nofollow"
class="external text"
href="https://github.com/JeffersonLab/HDGeant4/issues/182">Issue
#182</a>, "Incorrect TAGH counter number assignment."
Richard will review the changes proposed in the pull
request.

<h3><span class="mw-headline" id="New_Frontiers">New
Frontiers</span></h3>
<p>We discussed other areas of the simulation that need
study/development. Among them:
</p>
<ul>
<li> Kaons in the forward direction</li>
<li> Slow kaons in the BCAL</li>
<li> Cerenkov photons in the light guides of the FCAL</li>
<li> Neutrons and K<sub>L</sub>s</li>
</ul>
