Hello All,<br>
<br>
This brings up two issues:<br>
<ul>
<li>Have we done a simulation to see the lateral extent of a
shower? Depending on the lateral extend, the size and to some
extent the shape of the individual modules dictates the energy
sharing and hence the position resolution.</li>
<li>If we decide to not have a regular lattice and go with squares
close packed into the center radius, we could mitigate this
slightly, but then we would get problems at the PVDIS inner
radius, unless we decide to make two separate mounting fixtures</li>
</ul>
