There is absolutely no reason to have a wall if it is not needed. Just local shielding in front of the pion detector has no negative consequences for any other part of the experiment, as far as I can tell. <div class="">Cheers, KK</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Oct 12, 2016, at 11:13 AM, Neven Simicevic <<a href="mailto:neven@phys.latech.edu" class="">neven@phys.latech.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">

Hello Everyone,<br class="">
<br class="">
I am not able to participate in the pion detector meeting because is
during my class time. <br class="">
From the previous simulation I am inclined to not the build a big
shielding wall behind the main detector, instead just shield the
pion detector. <br class="">
If we just shield pion detector the shielding will not be as big. In
the attached report I have compared the consequences if we us
tungsten instead of lead.<br class="">
<br class="">
You can look at the results.<br class="">
<br class="">
Cheers,<br class="">
